Note: Declaring is the way a programmer tells the compiler to expect a particular type, be it a variable, class/struct/union type, a function type (prototype) or a particular object instance. (ie. extern int i) Declaration never reserves any space for the variable or instance in the program's memory; it simply a "hint" to the compiler that a use of the variable or instance is expected in the program. This hinting is technically called "forward reference".

Note: extern int x; - is an external variable declaration. double pow(double, double); - is a function prototype declaration. Therefore, 1 and 3 are declarations. 2 is definition.
