Just to clarify what previous post is telling:
"using namespace std;"
... don't do that. Especially as a beginner - one benefits from clean namespace (not polluted with bazillion things a beginner does not even know exists from std and will bite him in the back). Etc: http://stackoverflow.com/questions/1452721/why-is-using-namespace-std-considered-bad-practice
I, personally, have never seen a necessity for "using namespace whatever" and consequently have never used it.
Thanks for clarifying that. I wanted to write more, but posting from a phone is so frustrating. ;)
#include <iostream>
#include <string>
using std::cout;
using std::endl;
using std::string;
// etc.
I think I'll thank to my first C++ book (from Sams, I later found out their books are considered bad) for not telling me to add that statement.1: If you want to use strings ( or don't want to write overly complex code to handle strings ) , better memorize these 2 lines of code
It's not really a good idea to tell a beginner to use a line of code that it's generally considered bad practice to use.
It is definitely not about liking or not, I have already seen 4 threads of people asking for help fixing bugs caused by this. One had a variable called max inside a class but, since they had this line in their code, were actually referring to std::max. Also seen this happen with one that had a type called map to store the game map.using namespace std; // some folks don't like using it due to "conflicts"
It is surely better, but even in this case one should never add this in a header file.Just out of curiosity. What do you C++ users think of this (using declaration vs. using directive). Is it still bad practice ?
