My if-else statement does not work, does anyone know how to fix it?

Question

Basically, I have a project due in about 2 days, and I cannot find how to make this if else statement work. I've done it before. I do not know what I am doing wrong.

#include <iostream>
using namespace std;

int main()
{
    int response;
    cout << "is your circuit a parallel circuit?";

    if (response == 'Y')
    {
        cout << "yes";
    }
    else (response == 'N')
    {
        cout << "no";
    }
    return 0;
}

I do not know what this means:

Answer 1

int response;

If you want to read a character, response should be a char not an int .

 if (response == 'Y')

You forgot to actually read the user input. Your compiler should have warned you for using response uninitialized.

 else (response == 'N')

This is the cause of the error you get. else has no condition. else is the case for "none of the other conditions are true ". You either want else if or no condition here.

Correct code could look like this:

#include <iostream>
int main() {
    char response;
    std::cout << "is your circuit a parallel circuit?";
    std::cin >> response;
    if (response == 'Y') {     
        std::cout << "YES";
    } else if (response == 'N') {
        std::cout << "NO";
    } else {
        std::cout << "invalid input";
    }
}
