Kako deklarisati promenjlivu tipa string?

Naisao sam na milion primera gde se to radi sa



medjutim to kod mene neće da se kompajluje... prijavljuje da string nije deklarisan tip...
Molim vas, pomagajte!

kako su mi je potreban operator+ ne mogu da koristim char string1[];
Znam da bi mogla da se napiše klasa koja bi deklarisala string tip i overloadovala operator+ ali mora da postoji jednostavniji način...

And don't be mad at me for crying for humanity,
call it pretensions but I got good intentions,
to keep my sanity, I'm hoping, fuck, there's gotta be
an answer to their strategies and their evil inventions... ~Looptroop

Ili da ne bi stalno pisao "std::" pre int main() stavi:

Hvala obojici!
Šta predstavlja "std::" prefix? Korišćenje stdlib headera?
