C Program to Print X Star Pattern using For Loop

#include <stdio.h>

int main()
{
    int i,j,n,k;
    char ch;

    printf("Enter number of rows: ");
    scanf("%d",&n);
    k=n*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;
}

The Output of the above c program; is as follows:

Enter number of rows: 5

*        *

C Program to Print X Star Pattern using While Loop

#include <stdio.h>

int main()
{
    int i,j,n,k;
    char ch;

    printf("Enter number of rows: ");
    scanf("%d",&n);

	i=1;

	k=n*2-1;

    while(i<=k)
    {

	    j=1;
		while(j<=k)
        {
		    if(j==i || j==k-i+1)
                printf("*");

			printf(" ");

		    j++;

        }


        printf("\n");
	    i++;
    }
