In class-based programming, objects are created as instances of classes by subroutines called constructors, and destroyed by destructors. An object is an instance of a class as it can access to all data types (primitive as well as non primitive), and methods etc., of a class. Therefore, objects may be called a class instances or class objects. C++ strings are sequences of characters stored in a char array. Strings are used to store words and text.
