C Program to Print Alphabet V Pattern

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

#include <stdio.h>

int main() {
	int rows;

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

	for (int i = 0; i < rows; i++)
	{
		for (int j = 0; j < 2 * rows; j++)
		{
			if ((i + j == 2 * rows - 2 || i == j) && (i < 2* rows / 2))
			{
				printf("*");
			}
			else
			{
				printf(" ");
			}
		}
		printf("\n");
	}
	return 0;
}

Enter Rows = 16
*                             * 
 *                           *  
  *                         *   
   *                       *    
    *                     *     
     *                   *      
      *                 *       
       *               *        
        *             *         
         *           *          
          *         *           
           *       *            
            *     *             
             *   *              
              * *               
               *                

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

#include <stdio.h>

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

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

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

Enter Rows = 18
*                                 * 
 *                               *  
  *                             *   
   *                           *    
    *                         *     
     *                       *      
      *                     *       
       *                   *        
        *                 *         
         *               *          
          *             *           
           *           *            
            *         *             
             *       *              
              *     *               
               *   *                
                * *                 
                 *                 

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

#include <stdio.h>
void alphabetVPat(int rows, char a) {
	for (int i = 0; i < rows; i++) {
		for (int j = 0; j < 2 * rows; j++) {
			if (((i + j == 2 * rows - 2 || i == j) && (i < 2* rows / 2))) {
				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);

	alphabetVPat(rows, a);
	return 0;
}
