Object Oriented Programming Questions Medium
The 'new' keyword in Object-Oriented Programming (OOP) is used to create an instance of a class or to allocate memory for an object. It is primarily used for dynamic memory allocation, allowing the creation of objects at runtime.
When the 'new' keyword is used, it allocates memory for the object on the heap and returns a pointer to the newly created object. This pointer can then be assigned to a variable, allowing access to the object's properties and methods.
The purpose of using 'new' is to instantiate objects from a class blueprint, enabling the creation of multiple instances of the same class. Each instance created using 'new' will have its own set of properties and can be manipulated independently.
Additionally, the 'new' keyword also invokes the constructor of the class, which is a special method responsible for initializing the newly created object. The constructor can be used to set initial values for the object's properties or perform any necessary setup tasks.
In summary, the purpose of the 'new' keyword in OOP is to dynamically allocate memory for objects, create instances of a class, and invoke the constructor to initialize the object.
