Thread: how to solve this bug??

when i run this code
instead of getting some expected out put i get

line 17: `main' must return `int'

but main is a void function

it cant return int
???

Code:

#include <stdio.h>
int a(int n,int count){
      int i;
      for(i=0;i<n;i++)
           count =a(i,count);
           return count+1;
}

int b(int n,int count) {
  int i;
  count =a(n,count);
     for(i=0;i<n;i++)
     count =b(i,count);
     return count;
  }

  void main (){
    int i;
    for (i=0;i<4;i++)
      printf("%d",a(i,0));
      printf("\n%d\n",a(i,10));

      for (i=0;i<4;i++)
        printf("%d",b(i,0));
        printf("\n%d\n",b(i,10));

  }
