Question

1a. Create a class named Computer
- Separate declaration from implementation (i.e. Header and CPP files)
1b. Add the following private member variables
- an int variable named year
- a string variable named model
- a string variable named purpose
1c Add the following public functions:
- Default constructor which sets numeric members to -1 and string members to the empty string
- Destructor to print "Removing instance from memory"
- A non-default constructor to set the year and model variables only. The "purpose" variable should be set to the empty string.
- A non-default constructor to set all THREE member variables.
- Accessor and Mutators for all THREE member variables

please have a run for c++, visual studio. thank you

CODE IN C++

#include <iostream>
#include<string>

using namespace std;

class Computer
{
private:
int year;
string model,purpose;
public:
  
Computer(); //default constructor
~Computer(); //destructor
  
  
Computer(int y,string const& m,string const& p); //nondefault constructor

//accessors and mutators
void setYear(int y1);
int getYear( void );
  
void setModel(string const& m);
string getModel( void );
  
void setPurpose(string const& p);
string getPurpose( void );
  
};

Computer::Computer(void)
{
year=-1;
model="";
purpose="";


}
Computer::Computer(int y,string const& m,string const& p)
{
year=y;
model=m;
purpose=p;


}
Computer::~Computer(void)
{
cout << "Removing instance from memory" << endl;
}

void Computer::setYear( int y1 )
{
year= y1;
}
int Computer::getYear( void )
{
return year;
}
void Computer::setModel( string const& m )
{
model=m;
}
string Computer::getModel( void )
{
return model;
}
void Computer::setPurpose( string const& p )
{
purpose=p;
}
string Computer::getPurpose( void )
{
return purpose;
}

int main()
{
Computer com;


Computer com1(1998,"unique","building");





  
com.setYear(1998);
cout << "Year is : " << com.getYear() <<endl;

com.setModel("unique");
cout << "Model is : " << com.getModel() <<endl;

com.setPurpose("building");
cout << "purpose is : " << com.getPurpose() <<endl;

return 0;
}
