where are the non-static member variables of a class initialized?
类的非静态成员变量在哪里初始化？
在类声明中还是在构造函数中？？谢谢
在构造函数中。构造函数用于初始化类的非静态成员。

class foo
{
static int num; // static variable don’t belong to any particular instance of a class.
foo(){}

所以，在对应的源文件中这样操作-
它在构造函数的初始化列表中。如果使用编译器生成的构造函数，那么原理是一样的，只是隐式生成。
最好在构造函数初始化列表中：
