What are the characteristics of C++ constructors?
- The constructor has the same name as the class, no return type, including the default constructor, copy constructor, parameterized constructor, etc.
- The constructor is automatically called when an object is created, to initialize the object’s member variables.
- Constructors can be overloaded, which means you can define multiple constructors based on the types or number of parameters passed in to distinguish between different constructors.
- If a constructor is not defined, the compiler will provide a default constructor to initialize the object’s member variables.
- Constructors can perform any initialization operations, such as allocating or opening files.
- Constructors can perform parameter validation and initialization.
- Constructors can be utilized by other functions, but are typically used for creating and initializing objects.
