This seems like a simple thing to me, but I have an entity class:
class Entity
{
private:
std::string m_Name;
public:
int x = 0, y = 0;
Entity() : m_Name("Undefined Entity") {
std::cout << m_Name << " Created!\n";
}
Entity(const std::string& name) : m_Name(name) {
std::cout << m_Name << " Created!\n";
}
~Entity() {
std::cout << m_Name << " Destroid\n";
}
const std::string GetName() { return m_Name; }
void PrintCords() { std::cout << x << ' , ' << y << '\n'; }
};
and in my main function I run the PrintCords function:
int main(void)
{
std::unique_ptr<Entity> j = std::make_unique<Entity>("Jeff");
std::cout << j->GetName() << '\n';
j->PrintCords();
}
Yet, when I run the program, I get seemingly random numbers:
021084480

You should compile with -Werror. This turns your warnings into errors. When you do this, you will see the following error:
prog.cpp:25:43: warning: multi-character character constant [-Wmultichar]
void PrintCords() { std::cout << x << ' , ' << y << '\n'; }
^~~~~
Which should indicate to you that something is wrong. If you change this to a string literal:
void PrintCords() { std::cout << x << " , " << y << '\n'; }
---> ^ ^
Then everything will be ok.
