namespaces helps to shorten codes. For example: instead of this: stdout::cout << "hello world!" << endl by using namespaces like using namespace std; the code becomes simpler like this: cout << "hello world!" << endl

you can do namespace a { void print(){ cout << "a"; } } namespace b { void print(){ cout << "b"; } } and now you can call a::print (); // a b::print (); // b or using namespace a; ... print(); //a [edit] the std namespace contains all C++ standard functions, classes, etc (only C++ headers like iostream, string, etc.. C headers like stdio.h (cstdio) or time.h (ctime) don't use namespace because C doesn't support namespace)
