C Program to Print Christmas Tree Star Pattern

Write a C program to print Christmas tree star pattern using for loop.

#include <stdio.h>

int main()
{
	int width, height, space, i, j, k, n = 1;

	printf("Please Enter Chirstmas Tree Width & Height = ");
	scanf("%d %d", &width, &height);

	space = width * height;

	printf("Printing Chirstmas Tree Pattern of Stars\n");

	for (int x = 1; x <= height; x++)
	{
		for (i = n; i <= width; i++)
		{
			for (j = space; j >= i; j--)
			{
				printf(" ");
			}
			for (k = 1; k <= i; k++)
			{
				printf("* ");
			}
			printf("\n");
		}
		n = n + 2;
		width = width + 2;
	}
	for (i = 1; i <= height - 1; i++)
	{
		for (j = space - 3; j >= 0; j--)
		{
			printf(" ");
		}
		for (k = 1; k <= height - 1; k++)
		{
			printf("* ");
		}
		printf("\n");
	}
}
C Program to Print Christmas Tree Star Pattern

This C example prints the Christmas tree pattern of stars using a while loop.

#include <stdio.h>

void ChirstmasTreePattern(int width, int height, char ch);

int main()
{
	int width, height, i, j, k, n = 1;
	char ch;

	printf("\nEnter Character for Chirstmas Tree Pattern = ");
	scanf("%c", &ch);
	
	printf("Please Enter Chirstmas Tree Width & Height = ");
	scanf("%d %d", &width, &height);
		
	int space = width * height;
		
	printf("Printing Chirstmas Tree Pattern of Stars\n");
	ChirstmasTreePattern(width, height, ch);	
}

void ChirstmasTreePattern(int width, int height, char ch)
{
	int space = width * height;
	int i, j, k, n = 1;
		
	for (int x = 1; x <= height; x++ ) 
	{
		for (i = n; i <= width; i++ )
		{
			for(j = space; j >= i; j--)
			{
				printf(" ");
			}
			for(k = 1; k <= i; k++)
			{
				printf("%c ", ch);
			}
			printf("\n");
		}
		n = n + 2;
		width = width + 2;		
	}
	for(i = 1; i <= height - 1; i++)
	{
		for(j = space - 3; j >= 0; j--)
		{
			printf(" ");
		}
		for(k = 1; k <= height - 1; k++)
		{
			printf("%c ", ch);
		}
		printf("\n");
	}	
}
