浅谈变量的存储位置

#include <iostream>
using namespace std;

static int a = 10;

extern int b = 20; // 其实extern 在此处是多余的
int c = 30;

int main()
{
cout << &a << endl;
cout << &b << endl;
cout << &c << endl;

static int d = 40;
cout << &d << endl;

int e = 50;
cout << &e << endl;

//extern int g = 20;  // error
//cout << &g << endl;

return 0;
}
