help with getline.

Could someone explain the proper usage of getline? I am trying to use it, but i do not understand it's formatting.

Getline is for C++. You are sure you are programming for C++ and not C?
Getline reads a line from the file stream and stores it into a std::string buffer.

Code:

std::string str;
getline(cin, str); // To read one line from the command prompt

well, that makes sense then. I'm trying to use something from the wrong language...
