Chapter 11, Problem 4PP
Enhance the definition of the class StringVar given in Displays 11.11 and 11.12by adding all of the following:
- Member function copyPiece, which returns a specified substring; member function oneChar, which returns a specified single character; and member function setChar, which changes a specified character
- An overloaded version of the == operator (note that only the string values have to be equal; the values of maxLength need not be the same)
- An overloaded version of + that performs concatenation of strings of type StringVar
- An overloaded version of the extraction operator >> that reads one word (as opposed to inputLine, which reads a whole line)
If you did the section on overloading the assignment operator, then add it as well. Also write a suitable test program and thoroughly test your class definition.

Students have asked these similar questions
a) Implement a class Point with three attributes, x, y, and z.b) Implement an init method with an optional parameter type: 1) Set the default value of x, y, and z to 0.c) Implement a display method to print the values of x, y, and z as the example output below.d) Instantiate two objects of type Point, one with arguments,1, 2, and 3, and the other one without any arguments.e) Call display() to print x, y, and z.
Example Output(x, y, z): (1, 2, 3)(x, y, z) : (0, 0, 0)
1) Consider the following class Date, which represents a date using three ints for month, day and year:
class Date
{
private:
int month;
int day;
int year;
public:
Date() { month = day = year = 0; }
Date(int m, int d, int y) { month = m; day = d; year = y; }
bool operator==(Date);
bool operator<(Date);
};
It asks to create an implementation for both overloaded operators. == should return true if the Date objects are equivalent and false if not. < should return true if the Date of the calling object (left object) comes before the parameter Date object (right object) and false if not.
Assume that all objects of class Date are valid, i.e. month is between 1 and 12, inclusive; day contains an appropriate day for the given month, and year can be anything. You don't need to demonstrate calling these operators.
2)
Consider the following class
class Department
{
private:
string name;
const long locationNo;
const longdeptId;
intNumOfEmployees;
static intnextDeptNo;
static intnextLocationNo;
public:
Department( );
Department(string theName, totalEmps)
void Print ( ) const;
}
Initialize both the values of nextDeptNo and nextLocationNo to 10000
Implement the default constructor to set the name to “Unknown”, locationNo to the current value of nextLocationNo, deptId to the current value of nextDeptNo and NumOfEmployees to zero. It should also increment the value of all static attributes by 1.
Implement the other constructor to set the name and NumOfEmployees to the values that are passed to the contractor. The values of the locationNo and deptId should be assigned to the current values of nextLocationNo and nextDeptNo, respectively. This constructor should also increment the values of all static attributes by 1.
The print function should print all values of all attributes (regular,…
