## Logic to print the X star pattern

This logic was submitted by a Codeforwin lover - Md Shahbaz.

Let us divide the given pattern logically in two different sections as -

Step by step descriptive logic to print X star pattern.

1. The pattern consists of exactly `N * 2 - 1` rows and columns. Hence run an outer loop to iterate through rows with structure `for(i=1; i<= count; i++)` (where `count = N * 2 - 1`).
2. Since each row contains exactly `N * 2 - 1` columns. Therefore, run inner loop as `for(j=1; j<=count; j++)`.
3. Inside this loop as you can notice that stars are printed for the below two cases, otherwise print space.
• For the first diagonal i.e. when row and column number both are equal. Means print star whenever `if(i == j)`.
• For the second diagonal i.e. stars are printed `if(j == count - i + 1)`.

## Program to print X star pattern

``````/**
* C program to print X star pattern series
*/

#include <stdio.h>

int main()
{
int i, j, N;
int count;

printf("Enter N: ");
scanf("%d", &N);

count = N * 2 - 1;

for(i=1; i<=count; i++)
{
for(j=1; j<=count; j++)
{
if(j==i || (j==count - i + 1))
{
printf("*");
}
else
{
printf(" ");
}
}

printf("\n");
}

return 0;
}``````
