Objective-C: What is the significance of the "@" (at) symbol for NSLog (@"abc");?

And also, why is it not necessary for, eg: 

printf ("abc")

UPDATE:
 NSLog(@"%@",dictionary)

Tells the compiler that i got string to fulfill the requirement of string argument.

Update: Sorry I was supposed to write the "NSLog" instead of printf. my mistake!

NSLog takes an NSString as argument. @"abc" denotes an NSString because of the @ sign, so that is a valid argument for NSLog. printf is a normal C function that takes a C string, which is simply created using "".

Because it requires NSString. Adding @declares value as type of NSObject (simplification).
