Uniform initialization

Starting from C++11 one can use uniform initialization syntax with array new-expressions: char* arr1 = new char[4]{'a','b','c' }; char* arr2 = new char[4]{ "abc" }; But how to initialize the string that is contained in the array (with uniform initialization syntax)? char* arr3 = new char[4]{ arr1 }; //Error: a value of type "char*" cannot used to initialize an entity of type "char"

The problem here is that new cannot be used to assign arrays given as arguments. Arrays must be given directly to new with {} enclosing the content (Known as a brace-enclosed initializer list, used for direct initialization). More details are given here: https://stackoverflow.com/a/27663805 Even arr2's construction throws an error as the const char* literal acts as an argument rather than a brace-enclosed initializer list.
