Order of initialization?

Question

C++ / C#

Here is the class:

class Exper 
{
private:
    int Number = 475;
public:
    Exper(const int & num): Number(num) 
    {
    }
};

What value will be assigned to the Number field first? num or 475?

struct S {
    int n = 42;
    S() : n(7) {} // will set n to 7, not 42
};
