C Program to print Alphabet Triangle

There are different triangles that can be printed. Triangles can be generated by alphabets or numbers. In this c program, we are going to print alphabet triangles.

Let's see the c example to print alphabet triangle.

1. #include<stdio.h>    
2. #include<stdlib.h>  
3. int main(){  
4.   int ch=65;    
5.     int i,j,k,m;    
6.   system("cls");  
7.     for(i=1;i<=5;i++)    
8.     {    
9.         for(j=5;j>=i;j--)    
10.             printf(" ");    
11.         for(k=1;k<=i;k++)    
12.             printf("%c",ch++);    
13.             ch--;    
14.         for(m=1;m<i;m++)    
15.             printf("%c",--ch);    
16.         printf("\n");    
17.         ch=65;    
18.     }    
19. return 0;  
20. }  

Output:

     A
    ABA
   ABCBA
  ABCDCBA
 ABCDEDCBA
