Pattern Program in C Programming Language (post - 1)

In this blog you will get * Pattern Programs. For chapterwise program list click here

This blog is our first blog for Pattern Programs. If you want to know more about * Pattern Programs also read from below link.

Program1:

#include
void main()
{
    int i, j ;
    for(i=1 ; i<=5 ; i++)
    {
        for(j=1 ; j<=5 ; j++)
        {
            printf("* ");
        }
        printf("\n");
    }
}

Output:

* * * * *
* * * * *
* * * * *
* * * * *
* * * * * 

Program2:

/**
 * C program to print square star pattern
 */

#include

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

    // Input number of rows from user
    printf("Enter number of rows: ");
    scanf("%d", &N);

    // Iterate over rows
    for(i=1; i<=N; i++)
    {
        // Iterate over columns
        for(j=1; j<=N; j++)
        {
            // Print star for each column
            printf("*");
        }
        
        // Move to the next line/row
        printf("\n");
    }

    return 0;
}

Output:

Enter number of rows: 6

            printf("\n");
    }
}

Output:
