overloading- having different functions with same function_names but must have different signatures(parameters).

overriding- if a base class have a member function and its derived class also have a member function with same name and signature then when that same name function is called in the main function with the object of derived class then the function in the derived class is called that means the function with sam ename in the base class overrides, and this is known as function overriding.
If you have to call the function of the base class then you can call it within the scope of derived class function by using ::(scope resolution) operator.
