C Program to Print Alphabet K Pattern

In this article, we will show how to write a C program to print the Alphabet K pattern or shape of stars using for loop, while loop, and functions.

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

int main()
{
    int rows, n;

    printf("Enter Rows = ");
    scanf("%d",&rows);

    n = rows / 2;

	for (int i = 0 ; i < rows; i++ )
	{
		printf("*");
		for (int j = 0 ; j <= n; j++ )
		{
			if (j == abs(n - i))
			{
				printf("*");
			}
			else
			{
				printf(" ");
			}

		}
		printf("\n");
	}

    return 0;
}
Enter Rows = 16
*        *
*       * 
*      *  
*     *   
*    *    
*   *     
*  *      
* *       
**        
* *       
*  *      
*   *     
*    *    
*     *   
*      *  
*       *

Instead of a for loop, this Alphabet K Pattern of stars program uses a while loop to iterate the rows and columns. For more star programs, click here.

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

int main()
{
    int i, j, rows, n;

    printf("Enter Rows = ");
    scanf("%d",&rows);

    n = rows / 2;
    i = 0 ;
	while ( i < rows )
	{
		printf("*");
		j = 0 ;
		while ( j <= n )
		{
			if (j == abs(n - i))
			{
				printf("*");
			}
			else
			{
				printf(" ");
			}
			j++;
		}
		printf("\n");
		i++;
	}

    return 0;
}
Enter Rows = 11
*     *
*    * 
*   *  
*  *   
* *    
**     
* *    
*  *   
*   *  
*    *

In this C program, we create an alphabetKPat function that accepts those values and prints the Alphabet K shape or pattern of the given char.

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

void alphabetKPat(int rows, char a)
{
	int n = rows / 2;

	for (int i = 0 ; i < rows; i++ )
	{
		printf("%c", a);
		for (int j = 0 ; j <= n; j++ )
		{
			if (j == abs(n - i))
			{
				printf("%c", a);
			}
			else
			{
				printf(" ");
			}
		}
		printf("\n");
	}
}

int main()
{
    int rows;
    char a;

    printf("Enter Alphabet =  ");
    scanf("%c", &a);

    printf("Enter Rows = ");
    scanf("%d",&rows);

    alphabetKPat(rows, a);
    return 0;
}
