Number Triangle Program

Q. Write a C program to print the following number triangle design:

1
232
34543
4567654

Ans.

/*c program for number triangle design*/
#include<stdio.h>
int main()
{

 int num,r,c,s,t,q;
 printf("Enter any number : ");
 scanf("%d", &num);
 for(r=1; r<=num; r++)
 {
  for(c=r, s=r; c>=1; c--,s++)
     printf("%d", s);
  for(q=r-1,t=s-2; q>=1; q--,t--)
     printf("%d", t);
  printf("\n");
 }
 return 0;
}

The output of above program would be:
