Question

Добавить авторскую функцию к коду с++ #include int main() { int n; float l; std::cin >> n >> l; switch (n) { case 1: std::cout << "Length dm: " << l / 10; break; case 2: std::cout << "Length km: " << l * 1000; break; case 3: std::cout << "Length m: " << l; break; case 4: std::cout << "Length mm: " << l / 1000; break; case 5: std::cout << "Length sm: " << l / 100; break; default: break; } std::cout << std::endl; system("pause"); return 0; }

Ответ:

Изи же

Объяснение:

#include

// Авторская функция, которая конвертирует длину из одних единиц измерения в другие

float convertLength(float l, int n)

{

switch (n)

{

case 1:

return l / 10;

break;

case 2:

return l * 1000;

break;

case 3:

return l;

break;

case 4:

return l / 1000;

break;

case 5:

return l / 100;

break;

default:

return 0;

break;

}

}

int main()

{

int n;

float l;

std::cin >> n >> l;

float convertedLength = convertLength(l, n);

std::cout << "Length ";

switch (n)

{

case 1:

std::cout << "dm: ";

break;

case 2:

std::cout << "km: ";

break;

case 3:

std::cout << "m: ";

break;

case 4:

std::cout << "mm: ";

break;

case 5:

std::cout << "sm: ";

break;

default:

break;

}

std::cout << convertedLength << std::endl;

system("pause");

return 0;

}

Adding an Author's Function to the Code

To add an author's function to the given code, you can follow these steps:

1. Define the function before the `main()` function. 2. Implement the desired functionality within the function. 3. Call the function from within the `switch` statement in the `main()` function.

Here's an example of how you can modify the code to add an author's function:

#include

// Function to calculate the area of a square
float calculateArea(float length) {
    return length * length;
}

int main() {
    int n;
    float l;
    std::cin >> n >> l;
    
    switch (n) {
        case 1:
            std::cout << "Length dm: " << l / 10;
            break;
        case 2:
            std::cout << "Length km: " << l * 1000;
            break;
        case 3:
            std::cout << "Length m: " << l;
            break;
        case 4:
            std::cout << "Length mm: " << l / 1000;
            break;
        case 5:
            std::cout << "Length sm: " << l / 100;
            break;
        default:
            break;
    }
    
    // Call the author's function to calculate the area of a square
    float area = calculateArea(l);
    std::cout << "\nArea of the square: " << area << std::endl;
    
    system("pause");
    return 0;
}

In this modified code, I added a function called `calculateArea()` that takes the length of a square as a parameter and returns the area of the square. The function is then called within the `switch` statement in the `main()` function to calculate and display the area of the square.

Please note that the code provided is just an example, and you can modify it according to your specific requirements.
