Chapter 2, exercise 4

4.  What does the following program do?

/* ex02-04.c */
#include <stdio.h>


int main(void)
{
  int ctr;


  for( ctr=65; ctr<91; ctr++ )
    printf("%c", ctr);


  return 0;
}
/* end of program */

(Assuming we're using ASCII)

It prints the capital letters from A to Z to the standard output.  It then exits normally.
