My coding teacher gave us this code and told us to add a betting system.
specifically:
"Add a betting system. The user should start out with $200 and be
able to bet any amount as long as they have money to bet.
EX: You have $200
Place your bet: $50 ...after a few hands
You have $30
Place your bet: $40
Sorry ... you don't have enough to place this bet
You have $75
Do you want to bet or quit?
Quit when the user has no money left, or wants to stop."
Here is the the code:
#include <stdio.h>
#include <time.h>

This is off-topic for two reasons. One you are asking us to write you code. We don't do that. You write the code and we review it. Second you didnt write this. Your teacher did. Please see the help center for more derails.

This is off-topic for two reasons. One you are asking us to write you code. We don't do that. You write the code and we review it. Second you didnt write this. Your teacher did. Please see the help center for more derails.
