Question

Redo lab 3 and 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. 3. 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.

write a program C++ about Copmputer struct

Answer 1

Program:

#include<iostream>
using namespace std;

struct Info
{
public:
int year;
string model,purpose;

Info()
{
year=2020;
model="default_Model";
purpose="default_Purpose";
}

Info(int yr,string mod,string p)
{
year=yr;
model=mod;
purpose=p;
}

void displayInfo()
{
cout<<"Year: "<<year<<endl;
cout<<"Model: "<<model<<endl;
cout<<"Purpose: "<<purpose<<endl;
}

};

int main()
{
cout<<"Default Constructor: \n"<<endl;
Info dc;
dc.displayInfo();

cout<<"\nNon-default Constructor: "<<endl;
int y;
string m,p;
cout<<"Enter a year: ";
cin>>y;
cout<<"Enter a model: ";
cin>>m;
cout<<"Enter a purpose: ";
cin>>p;
cout<<endl;
Info non_dc(y,m,p);
non_dc.displayInfo();
return 0;
}

Output:

Default Constructor: Year: 2020 Model: default_Model Purpose: default_Purpose Non-default Constructor: Enter a year: 2020 Enter a model: Non_default model Enter a purpose: Non_default_purpose Year: 2020 Model: Non default model Purpose: Non default purpose ...
