# VCasino
|
||||
VCasino is a very simple game made to learn V.
|
||||
|
||||
# Compile and Run
|
||||
|
||||
Use this to generate a binary and then launch the game.
|
||||
```bash
|
||||
v VCasino.v
|
||||
./VCasino
|
||||
```
|
||||
|
||||
And this to compile and launch the game directly.

A rich man's wife became sick, and when she felt that her end was drawing near,

she called her only daughter to her bedside and said, "Dear child, remain pious

and good, and then our dear God will always protect you, and I will look down
|

on you from heaven and be near you." With this she closed her eyes and died.
|

|

The girl went out to her mother's grave every day and wept, and she remained
|

pious and good. When winter came the snow spread a white cloth over the grave,

and when the spring sun had removed it again, the man took himself another
|
||||
wife.
|
||||
|
||||
This wife brought two daughters into the house with her. They were beautiful,
|
||||
with fair faces, but evil and dark hearts. Times soon grew very bad for the
|
||||
poor stepchild.
|
||||
|
||||
"Why should that stupid goose sit in the parlor with us?" they said. "If she
|
||||
wants to eat bread, then she will have to earn it. Out with this kitchen maid!"
|
||||
|
||||
They took her beautiful clothes away from her, dressed her in an old gray
|
||||
smock, and gave her wooden shoes. "Just look at the proud princess! How decked
|
||||
out she is!" they shouted and laughed as they led her into the kitchen.
|
||||
|
||||
There she had to do hard work from morning until evening, get up before
|
||||
daybreak, carry water, make the fires, cook, and wash. Besides this, the
|
||||
sisters did everything imaginable to hurt her. They made fun of her, scattered
|
||||
peas and lentils into the ashes for her, so that she had to sit and pick them
|
||||
out again. In the evening when she had worked herself weary, there was no bed
|
||||
for her. Instead she had to sleep by the hearth in the ashes. And because she
|
||||
always looked dusty and dirty, they called her Cinderella.
|
||||
|
||||
One day it happened that the father was going to the fair, and he asked his two
|
||||
stepdaughters what he should bring back for them.
|
||||
|
||||
"Beautiful dresses," said the one.
|
||||
|
||||
"Pearls and jewels," said the other.
|
||||
|
||||
"And you, Cinderella," he said, "what do you want?"
|
||||
|
||||
"Father, break off for me the first twig that brushes against your hat on your
|
||||
way home."
|
||||
|
||||
So he bought beautiful dresses, pearls, and jewels for his two stepdaughters.
|
||||
On his way home, as he was riding through a green thicket, a hazel twig brushed
|
||||
against him and knocked off his hat. Then he broke off the twig and took it
|
||||
with him. Arriving home, he gave his stepdaughters the things that they had
|
||||
asked for, and he gave Cinderella the twig from the hazel bush.
|
||||
|
||||
Cinderella thanked him, went to her mother's grave, and planted the branch on
|
||||
it, and she wept so much that her tears fell upon it and watered it. It grew
|
||||
and became a beautiful tree.
|
||||
|
||||
Cinderella went to this tree three times every day, and beneath it she wept and
|
||||
prayed. A white bird came to the tree every time, and whenever she expressed a
|
||||
wish, the bird would throw down to her what she had wished for.
|
||||
|
||||
Now it happened that the king proclaimed a festival that was to last three
|
||||
days. All the beautiful young girls in the land were invited, so that his son
|
||||
could select a bride for himself. When the two stepsisters heard that they too
|
||||
had been invited, they were in high spirits.
|
||||
|
||||
They called Cinderella, saying, "Comb our hair for us. Brush our shoes and
|
||||
fasten our buckles. We are going to the festival at the king's castle."
|
||||
|
||||
Cinderella obeyed, but wept, because she too would have liked to go to the
|
||||
dance with them. She begged her stepmother to allow her to go.
|
||||
|
||||
"You, Cinderella?" she said. "You, all covered with dust and dirt, and you want
|
||||
to go to the festival?. You have neither clothes nor shoes, and yet you want to
|
||||
dance!"
|
||||
|
||||
However, because Cinderella kept asking, the stepmother finally said, "I have
|
||||
scattered a bowl of lentils into the ashes for you. If you can pick them out
|
||||
again in two hours, then you may go with us."
|
||||
|
||||
The girl went through the back door into the garden, and called out, "You tame
|
||||
pigeons, you turtledoves, and all you birds beneath the sky, come and help me
|
||||
to gather:
|
||||
|
||||
The good ones go into the pot, The bad ones go into your crop." Two white
|
||||
pigeons came in through the kitchen window, and then the turtledoves, and
|
||||
finally all the birds beneath the sky came whirring and swarming in, and lit
|
||||
around the ashes. The pigeons nodded their heads and began to pick, pick, pick,
|
||||
pick. And the others also began to pick, pick, pick, pick. They gathered all
|
||||
the good grains into the bowl. Hardly one hour had passed before they were
|
||||
finished, and they all flew out again. The girl took the bowl to her
|
||||
stepmother, and was happy, thinking that now she would be allowed to go to the
|
||||
festival with them.
|
||||
|
||||
But the stepmother said, "No, Cinderella, you have no clothes, and you don't
|
||||
know how to dance. Everyone would only laugh at you."
|
||||
|
||||
Cinderella began to cry, and then the stepmother said, "You may go if you are
|
||||
able to pick two bowls of lentils out of the ashes for me in one hour,"
|
||||
thinking to herself, "She will never be able to do that."
|
||||
|
||||
The girl went through the back door into the garden, and called out, "You tame
|
||||
pigeons, you turtledoves, and all you birds beneath the sky, come and help me
|
||||
to gather:
|
||||
|
||||
The good ones go into the pot, The bad ones go into your crop." Two white
|
||||
pigeons came in through the kitchen window, and then the turtledoves, and
|
||||
finally all the birds beneath the sky came whirring and swarming in, and lit
|
||||
around the ashes. The pigeons nodded their heads and began to pick, pick, pick,
|
||||
pick. And the others also began to pick, pick, pick, pick. They gathered all
|
||||
the good grains into the bowls. Before a half hour had passed they were
|
||||
finished, and they all flew out again. The girl took the bowls to her
|
||||
stepmother, and was happy, thinking that now she would be allowed to go to the
|
||||
festival with them.
|
||||
|
||||
But the stepmother said, "It's no use. You are not coming with us, for you have
|
||||
no clothes, and you don't know how to dance. We would be ashamed of you." With
|
||||
this she turned her back on Cinderella, and hurried away with her two proud
|
||||
daughters.
|
||||
|
||||
Now that no one else was at home, Cinderella went to her mother's grave beneath
|
||||
the hazel tree, and cried out:
|
||||
|
||||
Shake and quiver, little tree, Throw gold and silver down to me. Then the bird
|
||||
threw a gold and silver dress down to her, and slippers embroidered with silk
|
||||
and silver. She quickly put on the dress and went to the festival. Her
|
||||
stepsisters and her stepmother did not recognize her. They thought she must be
|
||||
a foreign princess, for she looked so beautiful in the golden dress. They never
|
||||
once thought it was Cinderella, for they thought that she was sitting at home
|
||||
in the dirt, looking for lentils in the ashes.
|
||||
|
||||
The prince approached her, took her by the hand, and danced with her.
|
||||
Furthermore, he would dance with no one else. He never let go of her hand, and
|
||||
whenever anyone else came and asked her to dance, he would say, "She is my
|
||||
dance partner."
|
||||
|
||||
She danced until evening, and then she wanted to go home. But the prince said,
|
||||
"I will go along and escort you," for he wanted to see to whom the beautiful
|
||||
girl belonged. However, she eluded him and jumped into the pigeon coop. The
|
||||
prince waited until her father came, and then he told him that the unknown girl
|
||||
had jumped into the pigeon coop.
|
||||
|
||||
The old man thought, "Could it be Cinderella?"
|
||||
|
||||
He had them bring him an ax and a pick so that he could break the pigeon coop
|
||||
apart, but no one was inside. When they got home Cinderella was lying in the
|
||||
ashes, dressed in her dirty clothes. A dim little oil-lamp was burning in the
|
||||
fireplace. Cinderella had quickly jumped down from the back of the pigeon coop
|
||||
and had run to the hazel tree. There she had taken off her beautiful clothes
|
||||
and laid them on the grave, and the bird had taken them away again. Then,
|
||||
dressed in her gray smock, she had returned to the ashes in the kitchen.
|
||||
|
||||
The next day when the festival began anew, and her parents and her stepsisters
|
||||
had gone again, Cinderella went to the hazel tree and said:
|
||||
|
||||
Shake and quiver, little tree, Throw gold and silver down to me. Then the bird
|
||||
threw down an even more magnificent dress than on the preceding day. When
|
||||
Cinderella appeared at the festival in this dress, everyone was astonished at
|
||||
her beauty. The prince had waited until she came, then immediately took her by
|
||||
the hand, and danced only with her. When others came and asked her to dance
|
||||
with them, he said, "She is my dance partner." When evening came she wanted to
|
||||
leave, and the prince followed her, wanting to see into which house she went.
|
||||
But she ran away from him and into the garden behind the house. A beautiful
|
||||
tall tree stood there, on which hung the most magnificent pears. She climbed as
|
||||
nimbly as a squirrel into the branches, and the prince did not know where she
|
||||
had gone. He waited until her father came, then said to him, "The unknown girl
|
||||
has eluded me, and I believe she has climbed up the pear tree.
|
||||
|
||||
The father thought, "Could it be Cinderella?" He had an ax brought to him and
|
||||
cut down the tree, but no one was in it. When they came to the kitchen,
|
||||
Cinderella was lying there in the ashes as usual, for she had jumped down from
|
||||
the other side of the tree, had taken the beautiful dress back to the bird in
|
||||
the hazel tree, and had put on her gray smock.
|
||||
|
||||
On the third day, when her parents and sisters had gone away, Cinderella went
|
||||
again to her mother's grave and said to the tree:
|
||||
|
||||
Shake and quiver, little tree, Throw gold and silver down to me. This time the
|
||||
bird threw down to her a dress that was more splendid and magnificent than any
|
||||
she had yet had, and the slippers were of pure gold. When she arrived at the
|
||||
festival in this dress, everyone was so astonished that they did not know what
|
||||
to say. The prince danced only with her, and whenever anyone else asked her to
|
||||
dance, he would say, "She is my dance partner." When evening came Cinderella
|
||||
wanted to leave, and the prince tried to escort her, but she ran away from him
|
||||
so quickly that he could not follow her. The prince, however, had set a trap.
|
||||
He had had the entire stairway smeared with pitch. When she ran down the
|
||||
stairs, her left slipper stuck in the pitch. The prince picked it up. It was
|
||||
small and dainty, and of pure gold.
|
||||
|
||||
The next morning, he went with it to the man, and said to him, "No one shall be
|
||||
my wife except for the one whose foot fits this golden shoe."
|
||||
|
||||
The two sisters were happy to hear this, for they had pretty feet. With her
|
||||
mother standing by, the older one took the shoe into her bedroom to try it on.
|
||||
She could not get her big toe into it, for the shoe was too small for her. Then
|
||||
her mother gave her a knife and said, "Cut off your toe. When you are queen you
|
||||
will no longer have to go on foot."
|
||||
|
||||
The girl cut off her toe, forced her foot into the shoe, swallowed the pain,
|
||||
and went out to the prince. He took her on his horse as his bride and rode away
|
||||
with her. However, they had to ride past the grave, and there, on the hazel
|
||||
tree, sat the two pigeons, crying out:
|
||||
|
||||
Rook di goo, rook di goo! There's blood in the shoe. The shoe is too tight,
|
||||
This bride is not right! Then he looked at her foot and saw how the blood was
|
||||
running from it. He turned his horse around and took the false bride home
|
||||
again, saying that she was not the right one, and that the other sister should
|
||||
try on the shoe. She went into her bedroom, and got her toes into the shoe all
|
||||
right, but her heel was too large. Then her mother gave her a knife, and said,
|
||||
"Cut a piece off your heel. When you are queen you will no longer have to go on
|
||||
foot."
|
||||
|
||||
The girl cut a piece off her heel, forced her foot into the shoe, swallowed the
|
||||
pain, and went out to the prince. He took her on his horse as his bride and
|
||||
rode away with her. When they passed the hazel tree, the two pigeons were
|
||||
sitting in it, and they cried out:
|
||||
|
||||
Rook di goo, rook di goo! There's blood in the shoe. The shoe is too tight,
|
||||
This bride is not right! He looked down at her foot and saw how the blood was
|
||||
running out of her shoe, and how it had stained her white stocking all red.
|
||||
Then he turned his horse around and took the false bride home again. "This is
|
||||
not the right one, either," he said. "Don't you have another daughter?"
|
||||
|
||||
"No," said the man. "There is only a deformed little Cinderella from my first
|
||||
wife, but she cannot possibly be the bride."
|
||||
|
||||
The prince told him to send her to him, but the mother answered, "Oh, no, she
|
||||
is much too dirty. She cannot be seen."
|
||||
|
||||
But the prince insisted on it, and they had to call Cinderella. She first
|
||||
washed her hands and face clean, and then went and bowed down before the
|
||||
prince, who gave her the golden shoe. She sat down on a stool, pulled her foot
|
||||
out of the heavy wooden shoe, and put it into the slipper, and it fitted her
|
||||
perfectly.
|
||||
|
||||
When she stood up the prince looked into her face, and he recognized the
|
||||
beautiful girl who had danced with him. He cried out, "She is my true bride."
|
||||
|
||||
The stepmother and the two sisters were horrified and turned pale with anger.
|
||||
The prince, however, took Cinderella onto his horse and rode away with her. As
|
||||
they passed by the hazel tree, the two white pigeons cried out:
|
||||
|
||||
Rook di goo, rook di goo! No blood's in the shoe. The shoe's not too tight,
|
||||
This bride is right! After they had cried this out, they both flew down and
|
||||
lit on Cinderella's shoulders, one on the right, the other on the left, and
|
||||
remained sitting there. When the wedding with the prince was to be held, the
|
||||
two false sisters came, wanting to gain favor with Cinderella and to share her
|
||||
good fortune. When the bridal couple walked into the church, the older sister
|
||||
walked on their right side and the younger on their left side, and the pigeons
|
||||
pecked out one eye from each of them. Afterwards, as they came out of the
|
||||
church, the older one was on the left side, and the younger one on the right
|
||||
side, and then the pigeons pecked out the other eye from each of them. And
|
||||
thus, for their wickedness and falsehood, they were punished with blindness as
|
||||
long as they lived.
