    passing dynamic array to function

    HI,

    I'm trying to create a dynamic array in one function and then passing it to another function. However I am not able to get it to work ? can someone please tell me how to do this properly ?

    Heres my code -

    Code:
           void CreateCars()
          {
              Cars* cars = new SportsCar[50];
    	  for(int i = 0; i < 50; ++i)
    	 	cars[i].SetSpeed(rand()%100);
    	  carHandler = new CarHandler(cars,50);
           }

    Code:
    CarHandler::CarHandler(Car* car_array,int numCars)
    {
    	this->car_array = car_array;
            this->numCars = numCars;
    }
    Can someone tell me how to do this properly ?
    Thank you!

    CarHandler constructor receives a pointer to a Car but you are passing a pointer to a Cars

    sorry, that was a typo.
    Code:
    CarHandler::CarHandler(Cars* car_array,int numCars)
    {
    	this->car_array = car_array;
            this->numCars = numCars;
    }
    I have cars in both places, but it doesnt work.

    Can you specify more exactly how it does not work? What you have posted should work fine, though I urge you to use std::vector instead.

    Yes, It worked! The problem was further on in the code.

    Thanks everyone!
