8.6 CONSTRUCTORS FOR TYPE STRING

The basic thing in any class is the constructor. We have studied constructor overloading. Hence, let us develop a class string with two constructors.

Problem: Develop two suitable constructors for class STRING.

There can be many other ways to construct STRING. Let us choose our second constructor as one which creates a null string. See Program 8.9.
