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: Foo(int x, int y) : m_x { x }, m_y { y } // here's ...

c++initializer_listparametric_constructor 8th Feb 2021, 4:47 PM Ketan Lalcheta + 1 this "explicit" makes you unable to copy-initialization. You have to make it "X a(10)" and "X b(a)" so it is direct-initialization. You can use static_cast too, like "X c = (X)5" ...

Description I don't know if this is intended or not (although it seems very unlikely that it is), but when I make a class with a member json variable and assign it in the initializer list (with a parameter from the constructor), it alway...
