Q. Write a C program to print the following triangle.
| A | ||||||||
| A | B | A | ||||||
| A | B | C | B | A | ||||
| A | B | C | D | C | B | A | ||
| A | B | C | D | E | D | C | B | A |
Ans.
#include<stdio.h>
#include<conio.h>
int main()
{
char ch,r,c;
int sp;
printf("Enter character : ");
scanf("%c",&ch);
if(ch>=a && ch<=z)
ch=ch-32;
for(r=A; ch>=r; r++)
{
for(sp=ch-r; sp>=1; sp--)
printf(" ");
for(c=A; r>=c; c++)
printf("%c",c);
for(c=r-1; c>=A; c--)
printf("%c",c);
printf("
");
}
getch();
return 0;
}
