Calling derived class functions from a base class

[JCED]

Here is what I'm trying to do:

#include <iostream>

class Base
{
public:
    Base()
    {
        loop();
    }

    virtual void foo()
    {
        std::cout << "Base member called." << std::endl;
    }

    void loop()
    {
        while (true)
        {
            foo();
        }
    }
};

class Child : public Base
{
    void foo()
    {
        std::cout << "Child member called." << std::endl;
    }
};

int main()
{
    Child c;
}

The output is:

Base member called.
Base member called.
Base member called.
Base member called.
Base member called.
...

How can I get it to output this?:

Child member called.
Child member called.
Child member called.
Child member called.
Child member called.
...

Thanks,
JCED

Move the call of 'loop' in the Child constructor

[moorecm]

Think of the object being constructed one level (class) at a time from the base down through the children. In the base constructor, the object just became a Base, but is not yet a Child.

bazzy is right, that's what you ask for..

nice explanation.. ^^

the base class's constructor is called first before the derive class's contructor..
try to make a default constructor in your derive class in put the loop() function in it.. you'll see what i mean.

Thanks, everything works nicely now. (and thanks for explaining why) :)
