Write C++ code for a main function that creates instances of the template version of your Car class you just wrote within a trycatch statement. Create four cars. Two of them should set speed to a numeric value and two should use strings for speed. Overload the + operator on them by adding the Cars with numeric speed, adding the Cars with strings for speed, and adding one Car with a string and another with a number for speed.

Here is the code that was just written:

#include

using namespace std;

class Car {

private:

int speed;

public:

Car(int speed = 0) { this->speed = speed; }

// virtual void accelerate();

// virtual void stop();

// virtual void getSpeed() const;

// getSpeed function will output the speed of the car

void getSpeed() const { cout << "speed : " << this->speed << " "; }

Car operator-(const Car &aCar);

Car operator+(const Car &aCar);

};

Car Car::operator+(const Car &aCar) {

int sumOfSpeeds;

sumOfSpeeds = (this->speed + aCar.speed);

return Car(sumOfSpeeds);

}

Car Car::operator-(const Car &aCar) {

int difference;

difference = (this->speed - aCar.speed);

return Car(difference);

}

int main() {

// initializing c1 speed with 20 and c2 speed with 10

Car c1(20), c2(10);

// using + overloading operator

Car c3 = c1 + c2;

// using - overloading operator

Car c4 = c1 - c2;

c1.getSpeed(); // will print 20

c2.getSpeed(); // will print 10

c3.getSpeed(); // will print 30

c4.getSpeed(); // will print 10

return 0;

}
