You might see some C++ programs that runs without the standard namespace library. The using namespace std line can be omitted and replaced with the std keyword, followed by the :: operator for string (and cout) objects:

Example
Code:
#include <iostream>
#include <string>

int main() {
 std::string greeting = "Hello";
std::cout << greeting;
return 0;
}
