int strcmp(const char *s1, const char *s2);
void overdue();

int main(){
overdue();
}

void overdue(){
int x,overdue_fees;
char answ[10];
char yes [10] = "yes";
char no[10] = "no"; 
int ret = strcmp(yes, no);

     
system ("cls"); 
printf("\n <<<<<<<<<<<<<<<<<<<<<<<<**********OVERDUE ITEMS*********<<<<<<<<<<<<<<<<<<<<<<<<<< \n");
printf("\n");
printf("PLEASE ENTER BARCODE OF OVERDUE ITEM:\n ignore me!\n");
//search for barcode in active book loans and info on that loan

printf("Is it past the return date?\n");
fgets(answ,10,stdin);
printf(answ);
getchar();
if (strcmpi(answ,yes)==0){
                printf("By how many days?");
                getchar();
                scanf("%d",&x);
                getchar();
                while (x!=0){
                       overdue_fees=1*1;
                       printf("%d $",overdue_fees);
                       x++;
                       }
}
}

Firstly, presentation is paramount. Please wrap your code in code tags. Use the edit button to edit your post.

You may be frantic but there's no need to panic, this is a solvable problem.
I haven't run your program yet but there are a few issues.

Why are you using your own prototype for strcmp at the top? There should already be one in string.h. Also, when you call it you have strcmpi. There's a such thing as stricmp (for case insensitive comparisons) but it's not standard.

Also, you presumably pad your yes and no strings with extra spaces so they are guaranteed not to match up with whatever you enter. char yes[] = "yes" will do.

What is the value of x when you enter your while loop?
