有没有什么办法可以使用在一个函数中定义的常量变量可以被c++中同一程序中的其他函数使用

#include<iostream>
using namespace std;

const int GLOBAL_CONSTANT = 10;

void function1()
{
    cout << "Global Constant: " << GLOBAL_CONSTANT << endl;
}

void function2()
{
    cout << "Global Constant: " << GLOBAL_CONSTANT << endl;
}

int main()
{
    function1();
    function2();
    return 0;
}

#include<iostream>
using namespace std;

void function1()
{
    static const int STATIC_CONSTANT = 10;
    cout << "Static Constant: " << STATIC_CONSTANT << endl;
}

void function2()
{
    extern const int STATIC_CONSTANT; // 引用静态变量
    cout << "Static Constant: " << STATIC_CONSTANT << endl;
}

int main()
{
    function1();
    function2();
    return 0;
}
