1. ## Please check over my Roulette Program

Hi I'm a beginner trying to write a roulette program with 3 modes of playing: straight-bets, odd/even, and red/black.

I've been having problems with the second 2 modes. Any suggestions are very much appreciated! (This is my first post so hopefully I pasted it correctly)

Code:
```#include <stdio.h>#include <stdlib.h>
#include <time.h>
//print block letters
void print_title(void);
//Spin roulette
int spin_roulette(void);

int main (void)
{
//Variables
int betmode;
int straightbet, cashbet, parity;
int number;
int balance;
char colorbet, R, B;

//Arrays
int red[18]={1,3,5,7,9,12,14,16,18,19,21,23,25,27,30,32,34,36};
int black[18]={2,4,6,8,10,11,13,15,17,20,22,24,26,28,29,31,33,35};

//Welcome & Title
printf("******************************************************************\n");
printf("******************************************************************\n");
print_title();
printf("\n******************************************************************\n");
printf("******************************************************************\n");

//Instructions for game
printf("\nEntering the casino, you have \$100\n");
printf("There are 3 types of bets you can make\n\n");
printf("1) Straight-up bet: Choose a single number. High risk, high payout! (35 to 1)\n\n");
printf("2) Red or black: Choose a color.(1 to 1)\n Red numbers are  1,3,5,7,9,12,14,16,18,19,21,23,25,27,30,32,34,36\n Black numbers are 2,4,6,8,10,11,13,15,17,20,22,24,26,28,29,31,33,35\n\n");
printf("3) Odd or even: Choose odd or even (1 to 1)");

//Select game mode
printf("\nPlease select your preferred type of bet. Enter 1, 2, or 3> ");
scanf("%d", &betmode);
balance=100;

//Loop to keep game going as long as you have cash
while (balance>0)
{
if (betmode==1)       //Straight bets
{
printf("\nGoing for the big money, eh?\n Enter a number between 1-36 you'd like to bet on> ");
scanf("%d", &straightbet);
printf("Now how much money are you willing to risk? Payout is 35 to 1> ");
scanf("%d", &cashbet);
printf("\nYou have bet \$%d on the number %d", cashbet, straightbet);
printf("\nPress ENTER to spin the roulette. Keep your fingers crossed!");
getchar();
getchar();
spin_roulette();
if (number==straightbet)
{balance += (cashbet*35);
printf("Winner Winner! You now have \$%d in your pocket", balance);}
else
balance -= cashbet;
printf("Sorry. You've lost \$%d. Your new balance is \$%d", cashbet, balance);
}
else if (betmode==2)         //Red or black bets
{
printf("\nAlright pick a color. Choose R for RED or B for BLACK> ");
scanf("&c", &colorbet);
printf("\nNow how much money are you willing to risk? Payout is 1 to 1> ");
scanf("%d", &cashbet);
printf("\nYou have bet \$%d on the color %c", cashbet, colorbet);
printf("\nPress ENTER to spin the roulette. Keep your fingers crossed!");
getchar();
getchar();
spin_roulette();
if (colorbet==R)
{
if (number==red[17])
{balance += cashbet;
printf("Winner Winner! You now have \$%d in your pocket", balance);}

}
else           //Odd or even bets
{  printf("Alright enter 1 for odd or 2 for even. Choose wisely!> ");
scanf("%d", &parity);
printf("\nNow how much money are you willing to risk? Payout is 1 to 1> ");
scanf("%d", &cashbet);
if (parity==1)
printf("\nYou have bet \$%d on odds", cashbet);
else
printf("\nYou have bet \$%d on evens", cashbet);
printf("\nPress ENTER to spin the roulette. Keep your fingers crossed!");
getchar();
getchar();
spin_roulette();

getchar();

void print_title(void)

int spin_roulette (void)

int number;
srand(time(NULL));
number=1+(rand()%36);
printf("The ball has landed on %d\n", number);
return number;
}```

2. Great first post, and welcome to the forum, Legodude!

I know zip about roulette, so I can't begin to comment on your code problem. Betting money on a little bouncing ball just never appealed to me, in the least.

3. > if (colorbet==R)
Should be
if (colorbet=='R')

Also check out A development process
So your main may look something like
Code:
```    if (betmode==1)       //Straight bets
playStraightBet();
else if (betmode==2)
playRedOrBlack();```
