C++ STL: How to write wrappers for cout, cerr, cin and endl?
- by Ashwin
I do not like using namespace std, but I am also tired of having to type std:: in front of every cout, cin, cerr and endl. So, I thought of giving them shorter new names like this:
// STLWrapper.h
#include <iostream>
#include <string>
extern std::ostream& Cout;
extern std::ostream& Cerr;
extern std::istream& Cin;
extern std::string& Endl;
// STLWrapper.cpp
#include "STLWrapper.h"
std::ostream& Cout = std::cout;
std::ostream& Cerr = std::cerr;
std::istream& Cerr = std::cin;
std::string _EndlStr("\n");
std::string& Endl = _EndlStr;
This works. But, are there any problems in the above which I am missing? Is there a better way to achieve the same?
