Function with Globals

Another slight change

 
/* --- sumVersion6.c --- */
#include <stdio.h>

int j;
int sum = 0;

int sumInts( int limit )
{
  
  for ( j=1; j<=limit; j++ )
    sum += j;
    
  return sum;
}
 
void main()
{   
  int sum = sumInts( 10 );
  printf( "sum of 1..10: %d\n", sum );    

  sum = sumInts( 5 );
  printf( "sum of 1..5: %d\n", sum );    
}

Now the program computes two sums using the function. The function uses a global variable.

What does the code write to the monitor?
