C Program - Tile Calculator - The Total Number of Tiles Necessary to Cover a Surface

This program calculates the total number of small elements required to cover a specified number of walls, given the dimensions of the walls and the dimensions of the small elements.

The main() function initializes integer variables big_width, big_height, small_width, small_height, and wall_number.

The program prompts the user to input the dimensions of the big wall (big_width and big_height), the dimensions of the small element (small_width and small_height), and the number of walls (wall_number).

The program then calculates the total surface area of the big wall (big_surface) and the small element (small_surface). It uses these values to calculate the number of small elements required to cover one wall (element_per_wall) and the total number of small elements required to cover all the walls (element_total).

Finally, the program prints the number of small elements required per wall and the total number of small elements required to cover all the walls to the console, and returns 0 to indicate successful program execution.

Note that the program assumes that the small elements will be arranged in a grid and that they will completely cover each wall without any overlap. It also assumes that the dimensions provided by the user are valid and that the division operations do not result in a divide-by-zero error. 

#include <stdio.h>

int main()
{

    int big_width, big_height;
    int small_width, small_height;
    int wall_number;

    printf("Big Width: ");
    scanf("%d", &big_width);

    printf("Big Height: ");
    scanf("%d", &big_height);

    printf("Small Width: ");
    scanf("%d", &small_width);

    printf("Small Height: ");
    scanf("%d", &small_height);

    printf("Number of Walls: ");
    scanf("%d", &wall_number);

    int big_surface = big_width * big_height;
    int small_surface = small_width * small_height;

    int element_per_wall = big_surface / small_surface;
    int element_total = wall_number * element_per_wall;

    printf("----------------------------- \n");
    printf("Element Number per Wall: %d   \n", element_per_wall);
    printf("Total Number of Elements: %d  \n", element_total);
    printf("----------------------------- \n");

    return 0;
}

Result: 

Big Width: 100
Big Height: 50
Small Width: 10
Small Height: 5
Number of Walls: 4
-----------------------------
Element Number per Wall: 100
Total Number of Elements: 400
-----------------------------

Here is a detailed explanation of each line and block of code in the program: 

#include <stdio.h>

This line includes the standard input-output library in the program. 

int main()
{

This line indicates the start of the main() function, which is the entry point of the program. 

    int big_width, big_height;
    int small_width, small_height;
    int wall_number;

These lines declare integer variables for the dimensions of the big wall (big_width and big_height), the dimensions of the small element (small_width and small_height), and the number of walls (wall_number). 

    printf("Big Width: ");
    scanf("%d", &big_width);

    printf("Big Height: ");
    scanf("%d", &big_height);

    printf("Small Width: ");
    scanf("%d", &small_width);

    printf("Small Height: ");
    scanf("%d", &small_height);

    printf("Number of Walls: ");
    scanf("%d", &wall_number);

These lines prompt the user to input the dimensions of the big wall (big_width and big_height), the dimensions of the small element (small_width and small_height), and the number of walls (wall_number) using printf() and scanf() functions. 

    int big_surface = big_width * big_height;
    int small_surface = small_width * small_height;

These lines calculate the surface area of the big wall (big_surface) and the small element (small_surface) by multiplying their respective dimensions. 

    int element_per_wall = big_surface / small_surface;
    int element_total = wall_number * element_per_wall;

These lines calculate the number of small elements required to cover one wall (element_per_wall) and the total number of small elements required to cover all the walls (element_total) using the surface area of the big wall and the small element. 

    printf("----------------------------- \n");
    printf("Element Number per Wall: %d   \n", element_per_wall);
    printf("Total Number of Elements: %d  \n", element_total);
    printf("----------------------------- \n");

These lines print the number of small elements required per wall (element_per_wall) and the total number of small elements required to cover all the walls (element_total) to the console using printf(). 

    return 0;
}

This line indicates the end of the main() function, and the program returns 0 to indicate successful program execution.
