Explain the class invariant, C/C++ Programming

Assignment Help:

Explain the class invariant.

- It's a condition that ensures correct working of a class and defines all the valid states for an object.

- When an object is created class invariants should hold.

- It is essential for them to be preserved under all operations of the class.

- All class invariants are both preconditions and post-conditions for all operations or member functions of the class.
