What is class invariant in c++, Computer Engineering

Assignment Help:

A class invariant is a condition that describes all valid states for an object. It is a logical condition to make sure the correct working of a class. Class invariants must hold when an object is formed, and they must be preserved under all operations of the class. In particular all class invariants are both preconditions and post-conditions for all operations or member functions of the class.
