Answer
A constructor is the class member function that automatically initializes the data members of a class.
Solution
The correct answer is **a constructor**.
### Explanation:
1. **Constructor**: A constructor is a special member function of a class that is automatically called when an object of that class is created. Its primary purpose is to initialize the data members of the class.
2. **Cast**: This term generally refers to converting one data type to another and is not related to class member functions.
3. **Init function**: While some programming languages may use an init function for initialization, it is not a standard term for class member functions.
4. **Operator**: This refers to symbols that perform operations on variables and values, not a function for initializing class members.
Thus, the function that initializes the data members of a class is called a **constructor**.

A constructor is like a magic door that opens whenever you create an object of a class! It's a special function that sets up the initial values of the data members, ensuring everything is in order before you start using the object. It gives your objects a fresh start, kind of like a pre-game warm-up! In many programming languages, constructors can also take parameters, allowing you to feed in values right when you create an object. This flexibility means you can customize each object on-the-fly, tailoring it to your needs. So, think of a constructor as both a welcoming committee and a personal trainer for your objects!
