C Program to Print X Star Pattern

Write a C Program to Print X Star Pattern using for loop. This c example uses nested for loop and if condition to pint the X pattern.

#include<stdio.h>
int main()
{
 	int i, j, k, rows; 
 	printf("Please Enter Number of rows =  ");
 	scanf("%d", &rows);

	k = rows * 2 - 1;

	for(i = 1; i <= k; i++)
	{
		for(j = 1; j <= k; j++)
		{
			if(j == i || j == (k - i + 1))
			{
				printf("*");
			}
			printf(" ");
		}
		printf("\n");
	}
 	return 0;
}

This C Program uses the while loop to Print X Star Pattern.

#include<stdio.h>
int main()
{
 	int i, j, k, rows; 
 	printf("Please Enter Number of rows =  ");
 	scanf("%d", &rows);

	k = rows * 2 - 1;
    i = 1;

	while(i <= k)
	{
        j = 1;
		while(j <= k)
		{
			if(j == i || j == (k - i + 1))
			{
				printf("*");
			}
			printf(" ");
            j++;
		}
		printf("\n");
        i++;
	}
 	return 0;
}

Please Enter Number of rows =  8
*              * 
 *            *  
  *          *   
   *        *    
    *      *     
     *    *      
      *  *       
       *        
      *  *       
     *    *      
    *      *     
   *        *    
  *          *   
 *            *  
*              * 

In this C Program, we enter a symbol and print that symbol in X Pattern using functions.

#include<stdio.h>

void xPatternFunc(int rows, char symbol)
{
    int i, j, k;

    k = rows * 2 - 1;

	for(i = 1; i <= k; i++)
	{
		for(j = 1; j <= k; j++)
		{
			if(j == i || j == (k - i + 1))
			{
				printf("%c", symbol);
			}
			printf(" ");
		}
		printf("\n");
	}
}
int main()
{
 	int rows;
    char symbol;
    
    printf("Please Enter Symbol to print =  ");
    scanf("%c", &symbol);

 	printf("Please Enter Number of rows =  ");
 	scanf("%d", &rows);
	
    xPatternFunc(rows, symbol);
 	return 0;
}

Please Enter Symbol to print =  $
Please Enter Number of rows =  7
