What is the difference between public private and protected inheritance in C

In C++, what is the distinction between public, private, and protected inheritance?

All of the inquiries I've read on SO are about particular situations.

To begin answering that question, let me characterise member accessors in my own terms. 

If you already know this, proceed to the section "next:".

I'm aware of three types of accessors: public, protected, and private.

Let:

class Base {
    public:
        int publicMember;
    protected:
        int protectedMember;
    private:
        int privateMember;
};

Everything that is aware of Base is likewise aware of the existence of publicMember in Base.

Only the children (and their offspring) are aware that protectedMember exists in Base.

PrivateMember is unknown to everyone except Base.

By "is aware of," I mean "acknowledges the existence of and hence has access to."

next:

The same is true for public, private, and protected inheritance. 

Consider the classes Base and Child, which both inherit from Base.

If the inheritance is made public, everyone who knows about Base and Child is likewise aware that Child is descended from Base.

Only Child and its children are aware that they inherit from Base if the inheritance is protected.

If the inheritance is kept confidential, no one knows about it except Child.

What is this weird colon-member (" : ") syntax in the constructor?

Foo(int num): bar(num) In C++, this is known as a Member Initializer List. Simply put, it sets the value of your member bar to num. There is a significant difference between initializing a member with the Member initializer list and assigning a value to it within the function Object() { [native code] } body. When you use the Member initializer list to initialise fields, the constructors are only called once, and the object is constructed and initialised in a single operation. If you use assignment, the fields will be initialised with default constructors and then reassigned with actual values (via the assignment operator). As you can see, there is an extra overhead of creation and assignment in the latter, which may be significant for user defined classes. Cost of Member Initialization =Object ...READ MORE
