Differ Symbol Pyramid

Q. write C program to print the following symbol pyramid as:

*
$$
***
$$$$

Ans.

/*c program for symbol pyramid*/
#include<stdio.h>
int main()
{
 int num,r,c;
 printf("Enter no. of rows : ");
 scanf("%d", &num);
 for(r=1; r<=num; r++)
 {
   for(c=1; c<=r; c++)
   {
     if(r%2==0)
        printf(" $");
     else
        printf(" *");
   }
   printf("\n");
 }
 getch();
 return 0;
}

The output of above program would be:

Ans.

/*c program for character and star pyramid*/
#include<stdio.h>
int main()
{
 char ch,r,c,q;
 printf("Enter ending character : ");
 scanf("%c", &ch);
 if(ch>='a' && ch<='z')
    ch=ch-32;
 for(r='A'; r<=ch; r++)
 {
  for(c='A'; c<=r; c++)
  {
    if(r%2==0)
       printf("*");
    else
       printf("%c",c);
  }
  printf("\n");
 }
 for(q=ch-1; q>='A'; q--)
 {
  for(c='A'; c<=q; c++)
  {
    if(q%2==0)
       printf("*");
    else
       printf("%c",c);
  }
  printf("\n");
