Puzzle SL1

Rule 1

What does the following code write to the monitor?

#include <stdio.h>
int main( void )
{
  int a = 1;
  int b = 2;
  
  printf("a=%d\tb=%d\n", a, b );
  
  system("pause"); /* remove if not needed */
  return 0;
}

The two variables a and b are defined at the beginning of a code block. They have block scope.
