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.

#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()…
