### Character - Symbol Pyramid

Q. Write a C program to print the following character and symbol design:

A
**
ABC
****
ABCDE
****
ABC
**
A

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");
}
getch();
return 0;
}

The output of above program would be:

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

1
**
123
****
12345
****
123
**
1

Ans.

/*c program for number and star pyramid*/
#include<stdio.h>
int main()
{
int num,r,c,n;
printf("Enter ending number : ");
scanf("%d"&num);
for(r=1; r<=num; r++)
{
for(c=1; c<=r; c++)
{
if(r%2==0)
printf("*");
else
printf("%d",c);
}
printf("\n");
}
for(n=num-1; n>=1; n--)
{
for(c=1; c<=n; c++)
{
if(n%2==0)
printf("*");
else
printf("%d",c);
}
printf("\n");
}
getch();
return 0;
}

The output of above program would be:
