Key Concepts

Object Declaration and Instantiation

Declaring an object, such as with a statement that names an instance of a class, automatically instantiates that object. This means that memory is allocated for the object based on its type at the point of declaration, typically on the system stack, without needing an explicit allocation command.

Automatic Storage Allocation

In many programming languages like C++, objects declared in a local scope are allocated on the stack by default. This automatic allocation means that the system handles the assignment and release of memory, so developers do not need to manually allocate memory before using the object.

Constructors

Constructors are special member functions within a class that initialize the newly created object. When an object is declared, its constructor is automatically called to set up initial values and allocate any necessary resources. This process happens seamlessly during object instantiation, ensuring the object is ready for use without additional memory allocation.
