Question
Which of the following correctly defines a pure virtual function?virtual void func() = 0;void virtual func() = 0;pure virtual void func() = 0;virtual void func();
Solution
The correct definition of a pure virtual function is:
virtual void func() = 0;
This is the syntax in C++ for declaring a pure virtual function. The "= 0" part means that the function is pure virtual, and must be overridden by any concrete (i.e., non-abstract) class that directly inherits from this class.
