Question

I am curious if there is any header file in C++ which can be used (included) instead of the standard namespace (namespace std) that works the same even in new versions of C++? I want to know if I can write code without using any namespaces and still be able to use the string data type.

Answer 1

string is in the std namespace, so you can’t completely disregard it.

There are options though:

using std::string;
using namespace std;
typedef std::string myString;

//or fully qualify the name
std::string mystr;

which you can put in a header and include that.

There, now I gave you the recipe for disaster. Don’t use it!

Namespaces are good. Learn to use them, rather than hacking your way around them.
