Character triangle

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


EDCBA
DCBA
CBA
BA
A


Ans:


/*c program for display the character triangle*/
#include<stdio.h>
#include<conio.h>
int main()
{
 char ch,r,c;
 int sp;
 printf("Enter last character of triangle : ");
 scanf("%c",&ch);
 if(ch>='a' && ch<='z')
    ch=ch-32;
 printf("\n");
 for(r='A'; r<=ch; ch--)
 {
   for(c=ch; c>=r; c--)
       printf("%c",c);
   printf("\n");
 }
 getch();
 return 0;
}

Ans.


/*c program for print above character structure*/
#include<stdio.h>
#include<conio.h>
int main()
{
  char ch,r,c,z;
  printf("Enter any character : ");
  scanf("%c", &ch);
  if(ch>='a' && ch<='z')
    ch=ch-32;
  for(r='A'; r<=ch; r++)
  {
     for(c='A'; c<=r; c++)
        printf("%c",r);
     printf("\n");
  }
  for(z=ch-1; z>='A'; z--)
  {
     for(c='A'; c<=z; c++)
        printf("%c",z);
     printf("\n");
  }
  getch();
  return 0;
}
Output:-
Enter any character : d

A
