베팅하는 부분의 함수이다.

int betting() //Asks user amount to bet
{
 printf("\n\nEnter Bet: $");
 scanf("%d", &bet);
 
 if (bet > cash) //If player tries to bet more money than player has
 {
        printf("\nYou cannot bet more money than you have.");
        printf("\nEnter Bet: ");
        scanf("%d", &bet);
        return bet;
 }
 else return bet;
} // End Function

이 부분을 보면,

베팅할 금액을 입력받는데 가지고 있는 돈보다 많은 양을 입력했을 경우

다시 입력하도록 된다. 그러나 반복문이 아니라서 한번 더 많은 양을 입력해도 그 값이 그대로 넘어간다.

 

Cash: $500
