Function with a static

Another slight change.

 
/* --- sumVersion8.c --- */
#include <stdio.h>

int sumInts( int limit )
{
  static int sum = 0;  
  int j;

  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 );    
}

The variable sum used in the functionis now block scope but static.

What does the program output?
