Question

Overload a relational operator for the Job class:
Assume that this operator is not overloaded for the Salary class.

a) Write how the function will be declared in your code.
b) Write an external function definition (not inside the class).

solve it in C++10

to solve this you nedd question number 1.

Create a composition between the classes Job and Salary.

Class Salary

a. data member:
   1. money
b. constructors:
   1. default constructor
   2. user defined constructor with a parameter to set money
c. standard accessor and mutator functions

Class Job

a. data members:
   title (name of the job)
   salary (object of type Salary)

b. constructors:
   1. default constructor
   2. user defined constructor to set title and salary
   3. implement constructor delegation

c. standard accessor and mutator function for title
d. accessor function to read the money value of the internal Salary object
e. mutator function to update the money value of the internal Salary object
f. accessor function to return a copy of the internal Salary object
g. mutator function to replace the internal Salary object

Answer 1

Output:

CODE:

 #include<iostream> using namespace std; //Salary class class Salary { //private members private: int money; public: //constructors Salary() { money=0; } Salary(int m) { money=m; } //accessor int getMoney() { return money; } //mutator void setMoney(int m) { money=m; } }; class Job { //private members private: string title; Salary salary; public: //constructors Job() { } Job(string t,Salary s) { title=t; salary=s; } Job(string t,int money) { Salary s(money); title=t; salary=s; } //accessors and mutators for title,money and salary string getTitle() { return title; } void setTitle(string t) { title=t; } int getMoney() { return salary.getMoney(); } void setMoney(int money) { salary.setMoney(money); } Salary getSalary() { return salary; } void setSalary(Salary s) { salary=s; } //operator < overloaded //returns true if this object's salary is less than Job j's salary bool operator<(Job &j) { return (salary.getMoney()<j.salary.getMoney()); } }; int main() { //create 2 objects and display their details Job j1("Engineer",100000); cout<<j1.getTitle()<<" "<<j1.getMoney()<<"\n"; Job j2("Scientist",11000); cout<<j2.getTitle()<<" "<<j2.getMoney()<<"\n"; //compare 2 objects, using < operator if(j2<j1) { cout<<j2.getTitle()<<" gets more salary than "<<j1.getTitle()<<endl; } else { cout<<j1.getTitle()<<" gets more salary than "<<j2.getTitle()<<endl; } return 0; }
