Answers

1.	It means functions with the same name but different code
2.	To use the same name, return type, and parameters, but to change the code in the function
3.	In overloading, you change the parameters; in overriding you do not.
4.	childclass: public classa,classb
5.	Its declaration line (i.e., its return type, name, and parameters)
6.	The actual code in the function
7.	Override the function in the derived class
8.	A function that must be overridden in any derived class
9.	A class that cannot be directly instantiated, but must be inherited to be used
10.	By making any of its functions a pure virtual function.
