Any advices for learning c++?

1. Memory Allocation - C++ typically does not make use of a garbage collector. Unused variables created on the heap are not cleaned up automatically. Therefore, it is best practice to use the stack as often as possible and avoid allocating heap memory. If you do have to allocate heap memory for an object (malloc), make sure that you free that memory when you are finished with it (delete). Otherwise you WILL get memory leaks in your program.
2. Pointers - Pointers require a developer to slightly change their way of thinking about memory. All data and variables are held in memory, and each piece of data can be referenced by its memory address. That's exactly what a pointer is. A reference to a memory address. You can use pointers to make very efficient and lightweight code by passing around a reference to the location in memory of a large object rather than the object itself. You can then access the object value by dereferencing the pointer, which simply means you are telling your function to look at the value in the memory location defined in the pointer. There are many other things you can do with pointers that make them a powerful tool.
3. Polymorphism - C++ is an object oriented language that encourages modular design by allowing you to define basic classes and extend them by creating child classes with additional or unique definitions. You can then reference a child class by one of its older generational types. For example, if I have a parent class called Toy, and I create a child class to extend it called Ball, then I can pass a Ball object in wherever a Toy object is asked for, because all Balls are Toys. (But be careful to avoid issues because not all Toys are Balls)

Start by testing everything in the module on its values and using inputs that you would typically assume. Then try inputs that are possible but less communal. This will flush out any secreted bugs. In fact, there is a skill of testing; you will be regularly build up your abilities with practice.
