Write a C program to print square star(*) pattern series of N rows. C program to print rectangle star(*) pattern in C of N rows and M columns. Logic to print square or rectangle star pattern of N rows in C programming.

Program Code

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

#include <stdio.h>

int main()
{
    int i, j, rows, columns;

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

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

    return 0;
}

Output

Enter number of rows: 5
Enter number of columns: 10

Explanation

Step by step descriptive logic to print rectangle star pattern.

Input number of rows and columns from user. Store it in a variable say rows and columns.
To iterate through rows, run an outer loop from 1 to rows. Define a loop with structure for(i=1; i<=rows; i++).
To iterate through columns, run an inner loop from 1 to columns. Define a loop with structure for(j=1; j<=columns; j++).
Inside inner loop print star *.
After printing all columns of a row. Move to next line i.e. print a new line.

How to learn from this program

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.

Practice suggestion

After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
