Address assignment of global variables, local variables, static variables and constants

#include <iostream>
using namespace std;
// Global variables 
int g_a = 10;
int g_b = 10;
const int c_g_a = 10;
const int c_g_b = 10;
int main()
{
    	// Global area 

	// Global variables 、 Static variables 、 Constant 

	// Create ordinary local variables 
	int a = 10;
	int b = 10;
	cout << " local variable a The address for ：" << (int)&a << endl;
	cout << " local variable b The address for ：" << (int)&b << endl;


	cout << " Global variables g_a The address for ：" << (int)&g_a << endl;
	cout << " Global variables g_b The address for ：" << (int)&g_b << endl;

	// Static variables 
	static int s_a = 10;
	static int s_b = 10;
	cout << " Static variables s_a The address for ：" << (int)&s_a << endl;
	cout << " Static variables s_b The address for ：" << (int)&s_b << endl;

	// Constant 
	// String constant —— String induced 
	cout << " The address of the string constant is ：" << (int)&"hello world" << endl;
	//const Decorated variable 
	//const Decorated global variables ,const Modified local variables 
	cout << " Global variables c_g_a The address for ：" << (int)&c_g_a << endl;
	cout << " Global variables c_g_b The address for ：" << (int)&c_g_b << endl;

	const int c_l_a = 10;
	const int c_l_b = 10;
	cout << " local variable c_l_a The address for ：" << (int)&c_l_a << endl;
	cout << " local variable c_l_b The address for ：" << (int)&c_l_b << endl;
	return 0;
}

Here you can see that local variables and local constants are in the same area , But not in the global area .
And global variables 、 Static variables 、 Both global constants and string variables are in the global area .
