Question

Which operator can be used to free the memory allocated for an object in C++?

(a) Free()

(b) delete

(c) Unallocate

(d) Collect

The question was asked by my college director while I was bunking the class.

My question is taken from Overloading Member Functions topic in section Member Functions & its Types of Object Oriented Programming

Answer 1

The correct choice is (b) delete

Easy explanation - The delete operator in C++ can be used to free the memory and resources held by an object. The function can be called explicitly whenever required. In C++ memory management must be done by the programmer. There is no automatic memory management in C++.
