Lets see a pattern -

Code:


#include

int main(void) {
 int i, j, k, s, p, q, sp, r, c = 1, nos = 13;
 for (i = 1; c <= 4; i++) {
  if ((i % 2) != 0) {  // Filters out the even line nos.
  for (j = 1; j <= i; j++) { // The upper left triangle
    printf("%2d", i);
  }
  for (s = nos; s >= 1; s--) {  // The spacing factor
    printf("  ");
  }
  for (k = 1; k <= i; k++) { // The upper right triangle
    printf("%2d", i);
  }
  printf("\n");
  nos = nos - 4;  // Space control
  ++c;
  }
 }
 nos = 10;  // Space control re intialized
 c = 1;
 for (p = 5; (c < 4 && p != 0); p--) {
  if ((p % 2) != 0) {  // Filters out the even row nos
  for (q = 1; q <= p; q++) {  // Lower left triangle
    printf("%2d", p);
  }
  for (sp = nos; sp >= 1; sp--) { // Spacing factor
    printf(" ");
  }
  for (r = 1; r <= p; r++) {  // Lower right triangle
    printf("%2d", p);
  }

  printf("\n");
  --c;
  nos = nos + 8;  // Spacing control.
  }
 }

 return 0;



and output will be :


Cheers !!
