What is the purpose of the destructor in C++?

Memory allocation
Overloading functions
To finalize an object and perform cleanup
To initialize variables

The correct answer is: To finalize an object and perform cleanup

A Memory allocation is incorrect because memory allocation in C++ is handled by the constructor and the destructor deals with resource deallocation. B: Overloading functions is also incorrect because overloading functions allows multiple functions with the same name but with different parameters. D: To initialize variables is also incorrect because variable initialization is done by the constructor. The purpose of the destructor in C++ is to finalize an object and perform cleanup operations before it is removed from the memory. This is especially useful for objects that have allocated resources such as memory on the heap or opened files. The destructor is automatically called when the object goes out of scope, and its main purpose is to free up any resources that were allocated during the object's lifetime. Therefore, options A, B, and D do not adequately represent the purpose of the destructor.
