difference between void and virtual void

[Mk87]

In the base class in visual studio, which time I must use void and virtual void and what's a difference between them?

[keskiverto]

void? The void, int, double, std::vector<Foo>, etc are return types of member functions (in your case). A function returns void, if it does not return a value.


That has nothing to do with virtual. Virtual is not about type. Virtual affects class inheritance.
