pass an argument to nested function

[Voroshek]

void func_3()
{
    cout << x;
};
void func_2()
{
    func_3();
};
void func_1()
{
    func_2();
};
int main()
{
    string x;
    func_1();
    return 0;
}

Also in main variable x defined, in func_3 used. I must pass this as parameter from func_1 to func_2 to func_3 or can easier?

You can not do that because func_1 does not accept any parameter.
