new()是否也为类的功能分配内存? [英] Does new() allocate memory for the functions of a class also?

问题描述

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

假设上面的代码，我尝试通过说new Animal()来初始化一个对象，这个new()是否也为函数f()分配了内存?

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

换句话说，如果我改为使用此类并执行了new Animal()吗?:

In other words, what is the difference in memory allocation terms if I had this class instead and did a new Animal() ? :

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

推荐答案

否.功能存在于文本页面中，因此没有为它们分配空间.

No. Functions exist in the text page and so no space is allocated for them.
