Question

write a function simulate the rolling of a roulette wheel (38 possible outcomes numbered 0-37)print the result of the roll (0-37).

update the number of times the result is equal to 17.

update the number of times the wheel has been rolled.

struct prob17{   

int times17;

int rolls;

};

void rollWheel(struct prob 17 * wheel)

Answer 1

#include<stdio.h>
#include<stdlib.h>

struct prob17{
   int times17;
   int rolls;
};
void rollWheel(struct prob17 * wheel);

int main(){
   struct prob17* wheel;
   while(1){
       printf("Enter \n1 to roll\n2 to stop:\n");
       int choice;
       scanf("%d",&choice);
       if(choice==1){
           rollWheel(wheel);
       }else if(choice==2){
           break;
       }else{
           printf("Invalid choice\n");
       }
   }
   printf("Number of times result is equal to 17: %d\n",wheel->times17);
   printf("Number of times wheel has been rolled: %d\n",wheel->rolls);
}

void rollWheel(struct prob17 * wheel){
   wheel->rolls++;
   int outcome=rand()%37;
   printf("\n\nResult of roll is : %d\n\n",outcome);
   if(outcome==17){
       wheel->times17++;
   }
}
