#include <stdio.h>

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

    for(i=1; i<=rows; i++)

        {
            // Print corner element
            if((i==1 || i==rows) && (j==1 || j==cols))
            {
                printf("0");

            else if(i==1 || i==rows || j==1 || j==cols)
            {
                // Print edge
                printf("1");
            }
            else
            {
                // Print center
                printf("0");
            }
        }

        printf("\n");
    }

    return 0;
}

Output

Enter rows: 5
Enter columns: 5

Basic C programming, Loop

Logic to print circle box number pattern

The given pattern is almost similar to one of previous explained pattern -

The only difference is zero gets printed for corner elements instead of 1.
Below is the step by step descriptive logic to print the given pattern.

Input number of rows and columns to print from user. Store it in some variable say rows and cols.
To iterate through rows run an outer loop from 1 to rows. The loop structure should look like for(i=1; i<=rows; i++).
To iterate though columns run an inner loop from 1 to cols. The loop structure should look like for(j=1; j<=cols; j++).
Inside the inner loop, print 1 for edges except for corner elements. Which is if(i==1 || i==rows || j==1 || j==rows) and not a corner then print 1 otherwise print 0.
Finally, move to the next line after printing all columns of a row.

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.
