C Program to Print Alphabet Z Pattern

In this article, we will show how to write a C program to print the Alphabet Z 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 < rows; j++)
		{
			if (i == 0 || i == rows - 1 || j == rows - i - 1)
			{
				printf("*");
			}
			else
			{
				printf(" ");
			}
		}
		printf("\n");
	}
}

Enter Rows = 15

Instead of a for loop, this Alphabet Z 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 < rows)
		{
			if (i == 0 || i == rows - 1 || j == rows - i - 1)
			{
				printf("*");
			}
			else
			{
				printf(" ");
			}
			j++;
		}
		printf("\n");
		i++;
	}
}

Enter Rows = 17

*****************

In this C program, we create an alphabetZPat function that accepts those values and prints the Alphabet Z Pattern of the given char.

#include <stdio.h>

void alphabetZPat(int rows, char a) 
{
	for (int i = 0; i < rows; i++) 
	{
		for (int j = 0; j < rows; j++) 
		{
			if (i == 0 || i == rows - 1 || j == rows - i - 1) 
			{
				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);

	alphabetZPat(rows, a);
	return 0;
}
