Thread: converting for loops to while loops

I am needing to convert the for loop to the while loop but I am unsure exactly how

Code:

#include <stdio.h>


int
main(void)
{
      int i, j;   /* loop control variables */


      printf("           I    J\n");        /* prints column labels     */


      for  (i = 1;  i < 4;  ++i) {       /* heading of outer for loop     */
      printf("Outer %6d\n", i);
      for  (j = 0;  j < i;  ++j) {      /* heading of inner loop     */
          printf("  Inner%9d\n", j);
      }   /* end of inner loop */
      }   /*  end of outer loop */


      return (0);
}
