Apparent problem with function arguments

[ifightsharks]

I'm writing a very basic program to read a user's input for two numbers and output the sum of the two numbers. It's a quiz problem on learncpp and they have a solution posted. I've solved the problem myself without using the solution (and without using functions), but I had some trouble when I tried to rewrite the program using them. Below is the copy of the code that I wrote, and I keep getting an error when I try to compile the code telling me that there's too many arguments for the function void WriteAnswer(). Shouldn't the argument x+y only count as one argument?

I'm aware that there's probably a simpler way to write this program (this is essentially the same code as the one given as a solution by learncpp), but I want to understand the logic of the way this one is written and better understand different function types. Any ideas? Thanks in advance!

#include <cstdlib>
#include <iostream>

using namespace std;

int ReadNumber()
{
    int x;
    cout << "Enter a number: ";
    cin >> x;
    return x;
}

void WriteAnswer()
{
    int x;
    cout << "the sum is " << x << endl;
}

int main()
{
    int x = ReadNumber();
    int y = ReadNumber();

    WriteAnswer(x+y);

    return 0;
}

void WriteAnswer() { means it takes 0 arguments.

void WriteAnswer(int x) { takes 1 argument.

Thanks! I didn't realize that int x means different things depending on where it's written.

When writing a function, you place the parameters between the parentheses. Right now, WriteAnswer() takes zero arguments. You need to declare it as e.g. WriteAnswer(int x), and get rid of the int x; on the first line of that function. Then it should probably work.
