Change the Computer class to a struct. 1. Keep the default and non-default constructors 2. Your struct does not need the accessors and mutators since all variables are public by default.

Question

3.Also Perforom the following:

Write a main():

- Create an instance of type Computer using the default constructor.

- Set the values for year, model, and purpose using any values you'd like.

- Print the values of year, model, and purpose to the standard output.

- Prompt the user to enter a value for year, model, and purpose

- Create a new instance of type Computer using the non-default constructor.

- Print the values of year, model, and purpose.

#include <iostream>

#include <string>

using namespace std;

class Computer {

private:

int year;

string model;

string purpose;

public:

Computer(int y, string m, string m2) {

year = y;

model = m;

purpose = m2;

}

~Computer() {

cout << "Removed from memory" << endl;

}

void setYear(int y) {

year = y;

}

int getYear() {

return year;

}

const string& getModel() {

return model;

}

void setModel(const string m) {

model = m;

}

const string getPurpose() {

return purpose;

}

void setPurpose(string p) {

this->purpose = p;

}

};

int main() {

// test code to make sure the class works as expected

Computer c1;

Computer c2(1901, "non-default1");

Computer c3(1902, "non-default2", "purpose2");

c1.setYear(1900);

c1.setModel("model1");

c1.setPurpose("purpose1");

cout << c1.getYear() << endl;

cout << c1.getModel() << endl;

cout << c1.getPurpose() << endl;

cout << c2.getYear() << endl;

cout << c2.getModel() << endl;

cout << c2.getPurpose() << endl;

cout << c3.getYear() << endl;

cout << c3.getModel() << endl;

cout << c3.getPurpose() << endl;

return 0;

}

Answer 1

This pretty straightforward.

Change the keyword "class" to "struct".

The constructor declarations are unchanged.

Eliminate the "private" declaration for the member variables, or move them to the public section. You'll want these to be public.

Get rid of the set() and get() accessor methods.

Change the accessor method calls to use member variables instead. E.g. change the line:

c1.setYear(1900);

To read:

c1.year = 1900;
