Hi
Im looking at some codes (in C++) and it gets quite confusing when there is operator overloading. Is there a simpler way to find out whether "()" or any other symbol is overloaded?

It has no book store that I can review those books, so I want to know, what is the different between those book and which…

Learning about programming is tough enough, but doing it online is next to impossible for me... Now, to get to the program, I am going to paste what I have so far. This…

After more than a few questions about deciding on C++ books I thought we could make a better community wiki version. Providing QUALITY books and an approximate skill level. Maybe we can add a short blurb/description about each book that you have personally read / benefited from. Feel free to debate…

There are two ways to overload operators for a C++ class:
Inside class
class Vector2
{
public:
float x, y ;
Vector2 operator+( const Vector2 & other )
{
Vector2 ans ;
ans.x = x + other.x ;
ans.y = y + other.y ;
return ans ;
}
} ;
Outside class
class…

Is there a comprehensive guide to operator overloading anywhere? Preferably online, but a book would be fine too. The description of the operator module leaves a lot out, such as including operators that can't be overloaded and missing the r operators.

Hello everybody,
I'm having trouble with overloading operator() with a const version:
#include <iostream>
#include <vector>
using namespace std;
class Matrix {
public:
Matrix(int m, int n) {
vector<double> tmp(m, 0.0);
data.resize(n, tmp);
}
~Matrix()…
