💻 Program Code

/**
 * C program to print box number pattern of 1's with 0 as center
 */

#include <stdio.h>

int main()
{
    int rows, cols, i, j;
    int centerRow, centerCol;

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

    /* Find center row and column */
    centerRow = (rows + 1) / 2;
    centerCol = (cols + 1) / 2;

    for(i=1; i<=rows; i++)
    {
        for(j=1; j<=cols; j++)
        {
            if(centerCol == j && centerRow == i)
            {
                printf("0");
            }
            else if(cols%2 == 0 && centerCol+1 == j)
            {
                if(centerRow == i || (rows%2 == 0 && centerRow+1 == i))
                    printf("0");
                else
                    printf("1");
            }
            else if(rows%2 == 0 && centerRow+1 == i)
            {
                if(centerCol == j || (cols%2 == 0 && centerCol+1 == j))
                    printf("0");
                else
                    printf("1");
            }
            else
            {
                printf("1");
            }
        }

        printf("\n");
    }

    return 0;
}

🖥 Program Output

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

Basic C programming, Loop

Logic to print box number pattern

In the above given pattern for every row and column 1 is printed except for the center row and column. Hence, to print this pattern we only need to focus on condition of center row and column.
Below is the step by step descriptive logic to print given pattern.

Input number of rows and columns from user. Store it in some variable say rows and cols.
Run an outer loop from 1 to rows, to iterate through rows. The loop structure should look like for(i=1; i<=rows; i++).
Run an inner loop from 1 to cols, to iterate through cols. The loop structure should look like for(j=1; j<=cols; j++).
Inside the inner before printing any number check the central row and column condition. Which is if(i==rows/2 && j==cols/2) then print 0, otherwise print 1.
Finally, move to next life after printing all columns of a row.

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
