Is Objective-C similar to C?
Syntax. Objective-C is a thin layer atop C and is a “strict superset” of C, meaning that it is possible to compile any C program with an Objective-C compiler and to freely include C language code within an Objective-C class. Objective-C derives its object syntax from Smalltalk.
What is NSString?
