Member intializer list error...

[AldenB]

class Something
{
public:
	Something(string n)
		:a{ n }, b{ 10 }, c{ 10 } {};

private:
	string a;
	int b;
	int c;
};

gives the error: error C2797: 'Something::a': list initialization inside member initializer list or non-static data member initializer is not implemented

However,

class Something
{
public:
	Something(string n)
		:b{ 10 }, c{ 10 } { a = n; };

private:
	string a;
	int b;
	int c;
};

Compiles without any error. Can someone please tell me why?

Your compiler is too old. The error message say this way of initializing data members has not been implemented yet. The code compiles fine for me with GCC 4.9.2.

Too old to compile

Something(string n)
		:a{ n } {};

but not too old to compile

	Something()
		:b{ 10 };

?

I'm using VS Community 2013, and I'm fairly certain I've intitialized strings in a class using a member initializer list. I don't see how my compiler can be too old quite frankly.

edit: I found a SO answer that says it works in VS 2015.

As a workaround you can use regular parentheses. a( n )

Awesome! Tyvm! I just discovered VS 2015 existed, I'm updating now. Thanks for your help!
