Example: Box with User-Defined Dimensions in C

// Box with User-Defined Dimensions
#include <stdio.h>

int main() {
    // Step 1: Declare variables for width and height
    int width, height;

    // Step 2: Prompt user for dimensions and read input
    printf("Enter the width of the box: ");
    scanf("%d", &width);
    printf("Enter the height of the box: ");
    scanf("%d", &height);

    // Step 3: Validate input to ensure reasonable dimensions
    if (width < 3 || height < 3) { // Minimum size for a recognizable box
        printf("Dimensions must be at least 3 for a proper box outline.\n");
        return 1; // Indicate an error
    }

    // Step 4: Loop through each row
    for (int i = 1; i <= height; i++) {
        // Step 5: Loop through each column in the current row
        for (int j = 1; j <= width; j++) {
            // Step 6: Check if current position is part of the border
            if (i == 1 || i == height || j == 1 || j == width) {
                printf("*"); // Print asterisk for border
            } else {
                printf(" "); // Print space for interior
            }
        }
        printf("\n"); // Move to the next line after each row
    }

    return 0;
