What is the difference between these two initializations?

Question

Is there a difference between how these are initialized ? Is one more favorable than the other ?

class Foo{
public:
    Foo();
private:
    int x_;
};

Foo::Foo() {
    this->x_ = 5;
}

Foo::Foo()
: x_(5)
{}

`this->x_ = 5;` is an assignment – Danh Nov 27 '16 at 03:35 — Danh, Nov 27 '16 at 03:35

This is member initialisation and is generally preferable.

Foo::Foo()
  : x_(5)
{}

Thank you. I didn't quite know the term for it. – TheWorstError Nov 27 '16 at 03:40
