Answer L4

#include <stdio.h>
#include <stdlib.h>

/* Puzzle A04 -- print the integers from -7 to +7, one per line */
int main()
{
  int j;
  for (j= -7; j<= 7; j++ )
  {
    printf("%3d\n", j);
  }

  return 0;
}

Comments: The above for statement is a sensible way to do this.

Would the following version also work, do you think? Or is there an off-by-one error lurking in the code?

#include <stdio.h>
#include <stdlib.h>

/* Puzzle A04 -- print the integers from -7 to +7, one per line */
int main()
{
  int j;
  for (j= 0; j<= 14; j++ )
  {
    printf("%3d\n", j-7 );
  }

  return 0;
}
