Nested Number Character Pyramid

Q. Write a C program to print the following nested number-character pyramid/pattern as:

A
1
BB
22
CCC
333

Ans.

/*c program for nested number character pyramid*/
#include<stdio.h>
int main()
{
 int num,r,c,z,n=1;
 char ch='A';
 printf("Enter Maximum number : ");
 scanf("%d", &num);

 for(r=1; r<=num; r++,ch++,n++)
 {
  for(c=1; c<=2; c++)
  {
   if(c%2==0)
   {
     for(z=1; z<=r; z++)
        printf("%d",n);
   }
   else
   {
     for(z=1; z<=r; z++)
        printf("%c",ch);
   }
   printf("\n");
  }
 }
 getch();
 return 0;
}
