    Unhappy using namespace std; question.

    What is
    using namespace std;
    and should I use it?

    It makes the namespace for the block that follows...
    You can use it like this:
    #include <iostream>
    using namespace std;
    int main()
         cout << "Hi" << endl;
         return 0;
    so you don't need to use std::cout, and std::endl; each time in your program...
