CS2400-Lab 7 Computer Class Solved

Design a computer class (Computer) that describes a computer object. A computer has the following properties:

•        Amount of Ram in GB (examples: 8, 16), defaults to 8.

•        Hard drive size in GB (examples: 500, 1000), defaults to 500.

•        Speed in GHz (examples: 1.6, 2.4), defaults to 1.6.

•        Type (laptop, desktop), defaults to "desktop"

 

 

Provide the following functions for the class:

 

•        A default constructor (constructor with no parameters) that initializes all the variables to their default values.

•        A constructor with four parameters to initialize all four member variables.

•        Getters(accessors) and setters(mutators) for all four member variables.

•        Calculate the price using the following formulas:

o Laptop: 600.00 + amount of ram in GB * 5.00 + Hard drive size * .15 +

(speed in GHz - 1.6) * 200 o Desktop: 400.00 + amount of ram in GB * 4.00 + Hard drive size in GB * .10 + (speed in GHz - 1.6) * 200

 

 

•        Overload the << operator to output all properties of a computer.

•        Overload the operator that reads all four properties of a computer.

•        Overload the == operator test if two computers are the same (all properties must match)

•        Overload the < operator that compares the prices of two computers.

 

You don’t have to check for invalid values.

Test the Computer class with the following main program.

      comp1.setRam(32);

      comp1.setHd(2000);

 

      int compRam = comp1.getRam();

      cout << "The computer ram was changed to "

      cout << "Computer type was changed to Desktop" << endl;      cout << comp1 << endl;

 

      Computer comp2;

      cout << "Enter specs of a computer (Ram, HD, Speed, Type)" << endl;       cin comp2;  cout << comp2 << endl;

      if (comp1 < comp2)

      {

            cout << "Computer 2 is more expensive" << endl;

      }

      if (comp1 == comp2)         

      {          

          cout << "comp1 and comp2 have the same specifications" << endl;

      }

 

      return 0;
