We have studied interactive constructors. They help us in creating objects with input from keyboard. Let us use this concept with class STRING.

Program: Write a program to illustrate Interactive constructor for class STRING.

Solution: In general, to read any arbitrary string (including blanks) we have to use methods gets() or getline(). If we want a method independent of these routines, we will have to read characters directly from the console. For this purpose, we can use getche() function from header “conio.h”.
