Question: Can u have inline virtual functions in a class?

Answer:

Source: CoolInterview.com

Yu may, but the compiler will turn down the inline request and treat it as a normal function.

The reason virtual fn cannot be inline are that a vtab is created for every class that have the address of all member function. Since inline fn do not have a address, virtual fns have to be treated non inline. Source: CoolInterview.com
