vector 走訪

#include <iostream>
#include <vector>

using namespace std;
int main()
{
    vector<int> vec({1, 2, 3});
    for (int i: vec)
        cout << i << ' ';
    return 0;
}

namespace

#include <iostream>
using namespace std;
namespace demo{
    class Demo {
    public:
        int a;
        int b;
        
        int do_something() {
            return a + b;
        }
    };
}

int main() {
    demo::Demo d;
    d.a = 55;
    d.b = 66;
    cout << d.do_something() << std::endl;
    
    return 0;
}
