C Program to Print K Shape Alphabets Pattern

Write a C program to print K shape alphabets pattern using for loop.

#include <stdio.h>

int main()
{
    int i, j, rows, alphabet;
    
    printf("Enter K Shape Alphabets Pattern Rows = ");
    scanf("%d",&rows);

    printf("\nThe K Shape Alphabets/Characters Pattern\n"); 
    
    for (i = rows - 1; i >= 0; i-- ) 
	{
		alphabet = 65;
		for (j = 0 ; j <= i; j++ ) 	
		{
			printf("%c ", alphabet + j);
		}
		printf("\n");
	}
		
	for (i = 1 ; i < rows; i++ ) 
	{
		alphabet = 65;
		for (j = 0 ; j <= i; j++ ) 	
		{
			printf("%c ", alphabet + j);
		}
		printf("\n");
	}
    return 0;
}

This C example prints a K shape pattern of alphabets using a while loop.

#include <stdio.h>

int main()
{
    int i, j, rows, alphabet;
    
    printf("Enter K Shape Alphabets Pattern Rows = ");
    scanf("%d",&rows);

    printf("\nThe K Shape Alphabets/Characters Pattern\n");

	i = rows - 1;
	
	while (i >= 0 ) 
	{
		alphabet = 65;
		j = 0 ;
		while ( j <= i) 	
		{
			printf("%c ", alphabet + j);
			j++;
		}
		printf("\n");
		i--;
	}
		
	i = 1 ;
	while ( i < rows ) 
	{
		alphabet = 65;
		j = 0 ;
		while ( j <= i ) 	
		{
			printf("%c ", alphabet + j);
			j++;
		}
		printf("\n");
		i++;
	} 
    return 0;
}

Enter K Shape Alphabets Pattern Rows = 8

C Program to display a K shape alphabets pattern using a do while loop.

#include <stdio.h>

int main()
{
    int i, j, rows, alphabet;
    
    printf("Enter K Shape Alphabets Pattern Rows = ");
    scanf("%d",&rows);

    printf("\nThe K Shape Alphabets/Characters Pattern\n");

	i = rows - 1;
	
	do
	{
		alphabet = 65;
		j = 0 ;
		do	
		{
			printf("%c ", alphabet + j);

		} while ( ++j <= i) ;
		printf("\n");

	} while (--i >= 0 );
		
	i = 1 ;
	do 
	{
		alphabet = 65;
		j = 0 ;
		do	
		{
			printf("%c ", alphabet + j);

		} while ( ++j <= i );
		printf("\n");

	} while ( ++i < rows );
    return 0;
}
