Question

wiHi everyone since last time i found extreme help on here, im gonna ask a question again

My code doesnt return right values :
something is wrong in the play_game function and i cant figure out what it is.I believe that all cases are covered but somehow they end up messed up.
also the code doesnt loop for everytime i want to play a game after the second game it stops.
this is not an assignment

any suggestion?

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

static int sum, point, win = 0, roll = 0;    
bool play_game(void);
int roll_dice(void);

int main(void){

srand(time(NULL)); 


play_game();

char input[10];

do{ point = 0;
    play_game();
    if(win == 1){ // I'm assuming that play returns whether you won or not
        printf("You won!\n");
    }else{
        printf("You lost!\n");
    }
    printf("Would you like to continue? y/n\n");
    gets(input);
}while(*input == 'y'); // gets() flushes the buffer for next time you need input
return 0;
}


bool play_game(void){

point=0;
roll_dice();
printf("Your point is %d\n", sum);

while(roll == 1) /* first round */
{
  if(sum == 7 || sum == 11)
     return win = 1;
  else if(sum == 2 || sum == 3 || sum == 12)
     return win = 0;
  else if(sum == 1 || sum == 4 || sum == 5 || sum == 6 || sum == 8 || sum == 9 || sum    == 10){
     point=sum;
     roll_dice();
     }

}

while(roll > 1) /* all others rounds*/
{  
      if(sum == 7)
        return win = 0;
      else if(sum == point)
        return win = 1;
      else if(sum != point || sum != 7)
      roll_dice();

} 

}

int roll_dice(void){

int a,b;

a=1+rand() % (6);
b=1+rand() % (6);
sum=a+b;
roll++;
printf("You rolled %d\n", sum);
return sum;

}

The loop needs to be more like:

main(){
    char input[10];

    do{
        score = 0; //Always initialize the score
        if(play_game()){ // I'm assuming that play returns whether you won or not
            printf("You won!\n");
        }else{
            printf("You lost!\n");
        }
        printf("Would you like to continue? y/n\n");
        gets_s(input, 9);
    }while(*input == 'y'); // gets() flushes the buffer for next time you need input
}
