1 - puts is an ANSI C function defined in the <stdio.h> header
2 - cout is not a function: it's a stream, associated to a file. When you do something like:
cout << "Hello" << endl;
You are using operator << (operator 'send to', which is a function, but written in C++, so unlike puts, it's Object-Oriented) : you are sending the string "Hello" to the stream cout, which is analogous to C's stdout.
3 - Same for getline and cin, except that getline is redefined in C++'s <iostream> header, so you need to be careful.

Prototype: int puts(const char *astring);
Puts is a function which will output the string pointed to by astring. It will then add a newline character. This is built in to the function. It returns a nonnegative integer if it was successful. It returns EOF if there was an error.

cout is an object of the std:stream class.It has many manipulators that allow specific formatting of output.
