The constructor is called when the object is created

class BaseClass {
public:
    BaseClass()
    {
        member = 0;
    };
    BaseClass(int initialiser)
    {
        member = initialiser;
    };
    int member;
}


BaseClass a;   // Calls default constructor

BaseClass *pB = new BaseClass(6);  // Calls constructor with 1 parameter

If you whant to write a derived class that calls a specific base cass constructor then you do it like this

class DerivedClass : PublicBaseClass
{
public:
    DerivedClass();
    DerivedClass(int initialiser);
}

DerivedClass::DerivedClass(int initialiser)
                 : BaseClass(initialiser)
{
}
