Next, write C++ code to create or modify a main function to use these two functions for overloading. Create two cars, each with different values stored in them, it's talking about the main function how to create and modify from overloading. Here is a copy of my code that's the coding I have I tried to run the code but getting errors.

int main() { vector aCar(2); aCar[0] = new Car(); aCar[1] = new Car(); Car* toACar = aCar[1]; aCar[1]->accelerate(); aCar[0]->accelerate(); aCar[0]->accelerate(); aCar[0]->operator+(*toACar); aCar[0]->operator-(*toACar); delete toACar; int intA; cin >> intA; };
