C++一些关于常量变量及内存分区的整理

代码示例：

#include 
using namespace std;

int g_x = 0; 					//全局非静态变
static int g_s_x = 1;			//全局静态变量
const int g_c_x = 2;			//全局常量
const string g_c_s = "abcd";	//全局字符串常

int main(int argc, char** argv) {
	int l_x = 3;				//局部非静态变量
	static int s_l_x = 4;		//局部静态变量
	const int c_l_x = 5;		//局部常量
	const string c_l_s = "efgh";//局部字符串常量
	
	cout << "全局非静态变量g_x:     " << &g_x << "   全局区" << endl;
	cout << "全局静态变量g_s_x:     " << &g_s_x << "   全局区" << endl;
	cout << "全局常量g_c_x:         " << &g_c_x << "   全局区" << endl;
	cout << "全局字符串常量g_c_s:   " << &g_c_s << "   全局区" << endl << endl;
	
	cout << "局部非静态变量l_x:     " << &l_x << "   栈区" << endl;
	cout << "局部静态变量s_l_x:     " << &s_l_x << "   全局区" << endl;
	cout << "局部常量c_l_x:         " << &c_l_x << "   栈区" << endl;
	cout << "局部字符串常量c_l_s:   " << &c_l_s << "   栈区" << endl;
	
	return 0;
}

运行结果：
