#include <iostream>

namespace first{
    int x = 1;
}

namespace second{
    int x = 2;
}

int main(){

    int x = 0;
    std::cout << x << std::endl;

    std::cout << first::x << std::endl; 
    
    using namespace second;
    std::cout << x << std::endl; 

    return 0;
} 

This is the code that I was working with. In this code I was expecting 0 1 2 as an output but why am I getting 0 1 0 as the output ?
