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++;
    }            
           
 
 
    return 0;
} 

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

*        *
