Question
I am tring to fing out the results of sum1,sum2 but I am having a problem compiling this code. What am I doing wrong.

int fun(int *k) {
  *k +=4;
  return 3 * (*k) - 1;
  }
void main() {
  int i = 10, j = 10, sum1, sum2;
  sum1 = (i / 2) + fun(&i);
  sum2 = fun(&j) + (j / 2);
  }


Answer
There is no compilation errors in this file.
There can only be warning, which you can ignore.
The main() function has to return int and you are making it return void.
Hence it is giving warning.

Here is the corrected code:

#include <stdio.h>

int fun(int *k)
{
       *k +=4;
       return 3 * (*k) - 1;
}

int main()
{
       int i = 10, j = 10, sum1, sum2;
       sum1 = (i / 2) + fun(&i);
       sum2 = fun(&j) + (j / 2);

       printf("SUM1 = %d\n", sum1);
       printf("SUM2 = %d\n", sum2);
}

If you are still having problems, add the exact errors that you are seeing and we will try to solve that.
