Does new () add memory for class functions?

Question

class Animal { public: int a; double d; int f(){ return 25;} }; 

Suppose for the above code I am trying to initialize an object by saying new Animal() , does this new() memory for the f() function?

In other words, what's the difference in memory allocation expressions if I had this class instead and made new Animal() ? :

 class Animal { public: int a; double d; }; 

Answer 1

Not. Functions exist on a text page, so no space is allocated for them.

Answer 2

For a class without virtual functions, the function itself does not occupy the data space. Functions are sections of code that can be executed to manipulate data. Data items must be highlighted.

When you have a virtual class, there is often an extra pointer to the virtual table. Note that vtable is a specific implementation. Although most compilers use them, you cannot count on the fact that it is always there.
