Question

Please Help. C++.

Need 3 attributes and 3 methods added to the code below.

Need the prototype added to the .h file......and the implementation in the .cpp file....thanks!

edited: I just need the above and then I was told to use the methods in the main program; for the vehicle. Any 3 attributes and any three methofds.

#include "Automobile.h"

using namespace std;

struct Address{

string street;

string city;

string state;

string zip;

};

struct Student{

string id;

string name;

Address homeAddress;

int numCredits; // total attempted credits

double gpa; // 4.0 scale

};

void boostGPA(const Student &s);

int main(){

vector carList;

{

Automobile spencerMobile("Yugo", "PutPut", 2004);

spencerMobile.drive(60);

}

system("pause");

return 0;

}

void boostGPA(const Student &s){

cout << s.gpa;

}

Your question isn't clear but I have tried to make sense out it, the best I could.
