Task-1: In Cartesian coordinate system, a linear equation represents a line passing through two discrete points, such as, (1, 1) and (4, 2), respectively. Hence, one can easily describe the “point” object with a C++ class as given below.
class Point {
public:
Point(); //default constructor
Point(…); //parameterized constructor
Point(…); //copy constructor
~Point(); //destructor
… set_x(…); //some member functions
… set_y(…);
… get_x(…);
… get_y(…);
… print(); //prints the point object using some format, e. g., [1,2]
private:
int x, y; //data members
};
On the other hand, in order to create a “line” object, one can think of executing data composition technique where the line object is composed of two discrete point objects. Hence, one can write the following:
class Line {
public:
Line(); //default constructor
Line(…); //parameterized constructor
Line(…); //copy constructor
~Line(); //destructor
… set_point1(…); //some member functions
… set_point2(…);
… get_slope(); //calculates the slope value
… print(); //prints the line object using some format
//e. g., A line passing through [2,2] and [4,4] with slope = 1.0
private:
Point p1, p2; //data composition!
};
a. Write definitions of the member functions listed above.
b. Rewrite the program by separating the implementation file from the interface using a header file.
Provide a driver program to test each implementation.

In this lab, you complete a python program that calculates an employee's annual bonus. input is an employee's first name, last name, salary, and numeric performance rating. if the rating is 1, 2, or 3, the bonus rate used is .25, .15, or .1 respectively. if the rating is 4 or higher, the rate is 0. the employee bonus is calculated by multiplying the bonus rate by the annual salary.
