class Matrix { struct Product { const Matrix* a; const Matrix* b; }; Matrix& operator = (const Product& p) { // if this matrix dims differ from required by product of p.a and p.b // reallocate it first and set dims // { // rows = ....; cols = ....;...
Support of `std::cbegin()`in C++14
c++,std,c++14,non-member-functions
GCC 4.9's support for C++14 is experimental and incomplete. But here, you can see that global functions cbegin, cend, rbegin, rend, crbegin, and crend for range access to containers, arrays and initializer lists. were added in GCC 5.1....
Non-friend, non-member functions increase encapsulation?
c++,encapsulation,member,non-member-functions
In theory, you sort of could do this, but you really don't want to. Let's consider why you don't want to do this (for the moment, in the original context--C++98/03, and ignoring the additions in C++11 and newer). First of all, it would mean that essentially all classes have to...
c++ create, assign and compare a new variable to two object inside an Operator Overloaded function.
c++,operator-overloading,non-member-functions
In the function Alien::Alien(int h, int w, char g) { height = h; weight = w; gender = g; int statusPoints = 0; } statusPoints is a function local variable that is not going to be useful for anything later. My suggestion: create a helper function in the .cpp file:...
C++: Difference Between Non-Member Function and Static Member Function?
c++,static-members,non-member-functions
static member functions can access private and protected sections of a class. Non-member functions cannot do that as default. They can do that only if a class grants them friendship. Another point to consider is that name of the static member functions are in the scope of the class. Multiple...
