I am new to C++ and I can’t understande what is wrong with my code I am using code block for my project and I don’t even know how I can see the erroe message. So I know what is wrong but I dont know why as all the files are normaly set up. This part of the code is just supose to make a chesboard like background. It tells me there is an error at the line 11 sf::RectangleShape rect(sf::Vector2f(600 / size, 600 / size));

#include <iostream>
#include <vector>
#include <cmath>
#include <SFML/Graphics.hpp>

int size = 8;
bool loop = true;
sf::RenderWindow window(sf::VideoMode(600, 600), "Echec Dames");

void drawBoard(int size) {
    sf::RectangleShape rect(sf::Vector2f(600 / size, 600 / size));
    bool colorSwitch = false;

    for (int n = 0; n < size; ++n) {
        for (int r = 0; r < size; ++r) {
            rect.setPosition(n * 600 / size, r * 600 / size);
            rect.setFillColor(colorSwitch ? sf::Color::White : sf::Color::Black);
            window.draw(rect);
            colorSwitch = !colorSwitch;
        }
        if (size % 2 == 0) {
            colorSwitch = !colorSwitch;
        }
    }
}

I tried looking up the syntax but I couldn’t finc any mistakes. Same with the modules or library (I don’t know how it is called). I at least expected to has an errore message but I can’t figure out how to see them.
