C program to display alphabet pyramid pattern

C program to display alphabet pyramid pattern

In this tutorial, we will discuss the concept of C program to display alphabet pyramid pattern

In this post, we will learn how to displayed  Pyramid triangle alphabet pattern  using for loop or nested for loop in C programming language

here, we displayed some alphabet Pyramid triangle pattern with coding using nested for loop and also we get input from user using scanf() function in C language

the user can provide numbers as they wish and get the alphabet pattern according to their input

Pyramid triangle alphabet pattern 1

Program 1

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int i,j,k,m,rows;
    printf("Enter the number of rows\n");
    scanf("%d",&rows);
    int ch=65;

    for(i=1; i<=rows; i++){//parent for loop
            for(j=rows; j>=i; j--){
            printf(" ");//print space for pyramid shape
            }
            for(k=1; k<=i; k++){
            printf("%c",ch++);
              }//make right site of pyramid
            ch--;

            for(m=1; m<i; m++){
                printf("%c",--ch);
            }//make left site of pyramid
            printf("\n");
    }
    getch();
    return 0;
}

When the above code is executed, it produces the following results

Enter the number of rows
6
               A
            ABA
         ABCBA
      ABCDCBA
   ABCDEDCBA
ABCDEFEDCBA

Pyramid triangle alphabet pattern 2

Program 2

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int i,j,rows;
    printf("Enter the number of rows\n");
    scanf("%d",&rows);

    for(i=1; i<=rows; i++){//parent for loop
            for(j=1; j<=rows-i; j++){
            printf(" ");//print space for pyramid shape
            }
            for(j=i; j>0; j--){
            printf("%c",(char)(j+64));
              }//make right site of pyramid

            for(j=2; j<=i; j++){
                printf("%c",(char)(j+64));
            }//make left site of pyramid
            printf("\n");
    }
    getch();
    return 0;
}

When the above code is executed, it produces the following results

Enter the number of rows

6

          A
        BAB
      CBABC
    DCBABCD
  EDCBABCDE
