Member initialization lists are something that is best learned by example. In the following example, our Foo(int, int) constructor has been updated to use a member initializer list to initialize m_x, and m_y: #include <iostream> class Foo { private: int m_x {}; int m_y {}; public...
In C, variables must be defined during creation. the same way in C++, we must initialize the Const and Reference variable during object creation by using Initialization list. if we do initialization after object creation (Inside constructor body), we will get compile time error. Member objects ...
If a private c++ class member variable (non-static) is a pointer, and it is NOT initialized in the constructor (either through an initialization list or an assignment in the constructor), what will its value be when the class is fully instantiated? Bonus question: If the answer to the abo...
