What is the difference between the two code and which should I use?

#include <iostream>
using namespace std;
int main() {
     char c;
     while ( cin.get(c) ) cout<<c;
} 

And 

#include <iostream>
using namespace std;
int main() {
     char c;
     while ( cin.get(c) ) cout.put(c);
}

[edit: whoops, not quite]~~Well, in this case they end up being exactly the same thing.~~ In general, though, you should prefer the stream insertion operator (operator<<), as it performs formatted input (assuming this is what you want).

From MSDN:

cout.put() is said to put a character in the stream, and the overloaded << operator writes to the stream. Basically, cout.put() can only write a single character the the console, while cout<< will write an entire string; if you pass a string to cout.put(), you will get a compiler error.

EDIT: Beaten to it...
