How to correctly initialize member variable of template type?
c++, templates
Solution
Like so:
T a{};
Pre-C++11, this was the simplest approximation:
T a = T();
But it requires `T` be copyable (though the copy is certainly going to be elided).
Problem
suggest i have a template function like following: ``` template<class T> void doSomething() { T a; // a is correctly initialized if T is a class with a default constructor ... }; ``` But variable a leaves uninitialized, if T is a primitive type. I can write T a(0), but this doesn't work if T is a class. Is there a way to initialize the variable in both cases (T == class, T == int, char, bool, ...)?
