Answer 2

True

False

Question 8

All virtual functions in C++ are dynamically bound, T/F?

Answer 8

Question 9

________ function in C++ is a function for which the compiler attempts to replace the function call with the function’s code itself, instead of performing the usual process of jumping to the function’s location in memory.
Virtual, final, inline, or friend?

Answer 9

Inline

Question 10

In C++, instead of storing the actual method implementation inside each object, the object has a pointer to a table (vtable) that stores the addresses of dynamically bound methods, T/F?
