If you don't put "using namespace std;", you have to precise the namespace any time you use something from the standard library, like std::cout.

Without using namespace std; when you write for example cout <<; you'd have to put std::cout <<; ------------------------------------------------------------------------ #include <iostream> int main() { std::cout << "Hello World"; system("pause"); return 0; } --------------------------------------------------------------------------- #include <iostream> using namespace std; int main() { cout << "Hello World"; system("pause"); return 0; }
