Copy constructors and Assignment Operators

Question

I wrote the following program to test when the copy constructor is called and when the assignment operator is called:

#include 

class Test
{
public:
    T         


        

Answer 1

C++ standard 8.5/12

The initialization that occurs in argument passing, function return, throwing an exception (15.1), handling an exception (15.3), and brace-enclosed initializer lists (8.5.1) is called copy-initialization and is equivalent to the form

T x = a;

The initialization that occurs in new expressions (5.3.4), static_cast expressions (5.2.9), functional notation type conversions (5.2.3), and base and member initializers (12.6.2) is called direct-initialization and is equivalent to the form

T x(a);
