How Do I Call a Base Class Constructor in C ?

Calling the Base Class Constructor in C

When inheriting from a base class in Java, the super() keyword is used to call the base class constructor. This allows for the initialization of the base class members within the derived class constructor.

Similarly, in C , the base class constructor can be called from the derived class constructor using the initializer list. This is a special syntax that precedes the constructor's body and is used to initialize the base class members.

Example:

Consider the following base class:

class BaseClass {
public:
    BaseClass(char *name);
};

When inheriting from this class, a constructor must be defined in the derived class to call the base class constructor with arguments.

class Foo : public BaseClass {
public:
    Foo() : BaseClass("asdf") {}
};

In this example, the Foo constructor initializes the base class with the "asdf" parameter. The initializer list is separated from the constructor body by a colon (:).

It's important to call the base class constructor before initializing any members of the derived class. Failure to do so will result in compilation errors due to missing arguments.
