Size of array object passed to function

Question

I am running the following code in C++:

class Tile {
    //class definition
};

bool myFunction(Tile* Tiles) {
    sizeof(Tiles);
    sizeof(Tiles[0]);
    /         


        

Answer 1

Arrays naturally decays to pointers, and when they do that all size information is lost. The most common solution is to pass along the number of elements in the array as an argument. It's also possible to use templates to deduce the array size.

Or use std::array (or std::vector, depending on situation) instead, which is the solution I recommend.
