Why std::cout instead of simply cout?
c++, iostream
Solution
It seems possible your class may have been using pre-standard C++. An easy way to tell, is to look at your old programs and check, do you see:
#include <iostream.h>
or
#include <iostream>
The former is pre-standard, and you'll be able to just say `cout` as opposed to `std::cout` without anything additional. You can get the same behavior in standard C++ by adding
using std::cout;
or
using namespace std;
Just one idea, anyway.
Problem
I get these error messages for all `cout` and `endl`: ``` main.cc:17:5: error: ‘cout’ was not declared in this scope main.cc:17:5: note: suggested alternative: /usr/include/c++/4.6/iostream:62:18: note: ‘std::cout’ ``` After following the suggestion, everything is fine. Now I am curious, why I had to do that. We used C++ in classes before, but I never had to write a `std::` before any of those commands. What might be different on this system?
