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 ...

One could argue -- as some have -- that C++ doesn't need this feature because it rarely uses POD aggregates. Instead of POD structs you'd normally use a class with proper constructors, and instead of arrays you'd better usestd::vectorandstd::array. This may be true to some extent ...
