C Alphabet Pattern Program | programming-point.com

In this article, we will learn how to print different C alphabet pattern program. We will use two loops to print pattern: one outer loop and one inner loop. The outer loop will point to each row of the pattern and the inner loop will print the characters. Following is the list of programs:

Pattern 1

Program
#include<stdio.h>
int main() 
{
  int i, j;
  char alphabet='A';
  for(i=1; i<=5; i++)
  {
    for (j=1; j<=i; j++)
    {
      printf("%c ", alphabet);
      alphabet++;
    }
    printf("\n");             
  }
  return 0;
}

Pattern 2

Program
#include<stdio.h>
int main() 
{
  int i, j;
  char alphabet='A';
  for(i=5; i>=1; i--)
  {
    for (j=1; j<=i; j++)
    {
      printf("%c ", alphabet);
      alphabet++;
    }
    printf("\n");             
  }
  return 0;
}

Pattern 3

Program
#include<stdio.h>
int main() 
{
  int i, j;
  char alphabet='A';
  for(i=1; i<=5; i++)
  {
    for (j=1; j<=i; j++)
    {
      alphabet = alphabet+j;
      printf("%c ", alphabet-1);
      alphabet='A';
    }
    printf("\n");             
  }
  return 0;
}

Pattern 4

Program
#include<stdio.h>

    {
      alphabet = alphabet+j;
	  printf("%c ", alphabet-1);

All the programs are compiled and executed in Dev C++ code editor and save with .c extension.
