To call a parent class constructor

How does C++ call the constructor of a parent class (even a parent's parent) in a child class?

In Java, we could have called the parent class constructor on the first line What should I do with C++

Write as follows

class SuperClass
{
    public:
        SuperClass(int foo) {}
};

class SubClass : public SuperClass
{
    public:
        SubClass(int foo, int bar): SuperClass(foo) {}
};

It's on public right now, In c++, the private/protected/public keyword is the same as in Java.
