Question

edit*
I’m dumb… Thanks for helping me this question is solved.
*
In my car class the code below keeps giving me an error on the << operators

cout << "Driver: " << driver->print(); 
cout << "Owner: " << owner->print();

The error says “no operator matches these operands.” This is my homework assignment so I do need to somehow from the driver call the print function. In the main function I’m not actually setting the driver or owner yet but that shouldn’t matter I wouldn’t think. Thanks in advance.

#include <iostream>
#include <string>
#include <vector>

using namespace std;

class Person
{
public:
Person(string _name,int _age)
{
    _name = name;
    _age = age;
    cout << "Name: " << name << endl;
    cout << "Age: " << age << endl;
}
string getName()
{
    return name;
}
int getAge()
{
    return age;
}
int incrementAge()
{
    age +=1;
    return age;
}
void print()
{
    cout << "Name: " << name << endl;
    cout << "Age: " << age << endl;

}


private:
string name;
int age;

};

class Car
{
public:
Car (string m)
{
    model = m;
}
void setDriver(Person *d)
{
    *driver = *d;
}
void setOwner(Person *o)
{
    *owner = *o;
}
void print()
{
    cout << "Model: " << model << endl;
    cout << "Driver: " << driver->print();
    cout << "Owner: " << owner->print();
}




private:

string model;
Person *owner;
Person *driver;


};

int main()
{
vector<Person*>people;
vector<Car*>cars;
string name = "";
int age = 0;
string model = 0;
int sentValue = 0;
while (sentValue != -1)
{
    cout << "Enter name: ";
    cin >> name;
    cout << "Enter age: ";
    cin >> age;


    people.push_back(new Person(name, age));
    cout << "Enter car model: ";
    cin >> model;
            cars.push_back(new Car(model));
    cout << "Press -1 to stop, or 1 to enter info for others: ";
    cin >> sentValue;
}






//display car model, 
//owner’s name and age,
//and driver’s name and age.

system("pause");
return 0;
   }

Your print() function already sends the output to cout, so there is no need to try to send it there again. Instead of

cout << "Driver: " << driver->print(); 

you probably want

cout << "Driver:" << endl;
driver->print();
