C Program to Print Diamond Alphabets Pattern

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

#include <stdio.h>

int main()
{
	int i, j, k, rows, alphabet = 64;

	printf("Enter Diamond Pattern of Alphabets Rows = ");
	scanf("%d", &rows);
		
	printf("Printing Diamond Alphabets Pattern\n");
	for (i = 1 ; i <= rows; i++ ) 
	{
		for (j = 1 ; j <= rows - i; j++ ) 
		{
			printf(" ");	
		}
		for (k = 1 ; k <= i * 2 - 1; k++ ) 
		{
			printf("%c", alphabet + k);
		}
		printf("\n");
	}
		
	for (i = rows - 1 ; i > 0; i-- ) 
	{
		for (j = 1 ; j <= rows - i; j++ ) 
		{
			printf(" ");
		}
		for (k = 1 ; k <= i * 2 - 1; k++ ) 
		{
			printf("%c", alphabet + k);
		}
		printf("\n");
	}
}
C Program to Print Diamond Alphabets Pattern

It is another way of writing the C program to display the diamond pattern of alphabets.

#include <stdio.h>

int main()
{
	int i, j, k, rows, alphabet = 65;

	printf("Enter Diamond Pattern of Alphabets Rows = ");
	scanf("%d", &rows);
		
	printf("Printing Diamond Alphabets Pattern\n");

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

	for (i = 0; i <= rows - 1; i++)
	{
		for (j = -1; j <= i; j++)
		{
			printf(" ");
		}
		for (k = 0; k <= rows - i - 2; k++)
		{
			printf("%c ", alphabet + k);
		}
		printf("\n");;
	}
}

This C example prints the Diamond pattern of alphabets using a while loop.

#include <stdio.h>

int main()
{
	int i, j, k, l, rows, alphabet = 64;

	printf("Enter Diamond Pattern of Alphabets Rows = ");
	scanf("%d", &rows);

	printf("Printing Diamond Alphabets Pattern\n");

	for (i = 1; i <= rows; i++)
	{
		for (j = 1; j <= rows - i; j++)
		{
			printf(" ");
		}
		for (k = i; k >= 1; k--)
		{
			printf("%c", alphabet + k);
		}
		for (l = 2; l <= i; l++)
		{
			printf("%c", alphabet + l);
		}
		printf("\n");
	}

	for (i = rows - 1; i > 0; i--)
	{
		for (j = 1; j <= rows - i; j++)
		{
			printf(" ");
		}
		for (k = i; k >= 1; k--)
		{
			printf("%c", alphabet + k);
		}
		for (l = 2; l <= i; l++)
		{
			printf("%c", alphabet + l);
		}
		printf("\n");
	}
}
