What is a Pointer in C Scaler Topics

A map is the best way to store where we can directly find and access the value using a key with the best time complexity. There are 2 important operators that we will use in pointers concepts i.e. We need a way to tell find() to compare the actual coordinates, and not the Coords pointers
