Question

7 Define a class String that could work as a user-defined string type. Include constructors that will enable us to create an uninitialized string: String s1; // string with length 0 And also initialize an object with a string constant at the time of creation like String s2("Well done!"); Include a function that adds two strings to make a third string. Note that the statement S2 = s1; will be perfectly reasonable expression to copy one string to another. Write a complete program to test your class to see that it does the following tasks: \(a\) Creates uninitialized string objects. \(b\) Creates objects with string constants. \(c\) Concatenates two strings properly. \(d\) Displays a desired string object.
