First of all, there are no const variables. A variable is something that may
change, that is variable. A constant is something that will not change (once
it has been initialiazied). So you probably mean a constant data member.

A constant data member can only be initialized in the initializer list of a
constructor:

class SomeClass
{
const int cannotBeModifie d;
public:
SomeClass(int initilialValue) : cannotBeModifie d(initialValue)
{}
};

In an initialiser list in the constrictor

struct X
{
const int n;

X() : n(42) {}
};

Posting wrong answer twice doesn't make it right.

Why don't you give the correct answer, then.

Well, forget about it... Here is the correct answer:

[*************** ************ HEADER FILE *************** *************]
class MyClass{
public:
...
private:
...
const static int _somevar;
};

[*************** ************* C++ FILE *************** *************** **]
....
int MyClass::_somev ar = somevalue;
