[Solved] Colon after #define in Objective-C [duplicate]

Question

Macros are just replaced by their definition. When you #define k 1024; and write if(k==1024)... what the compiler actually sees is:

if(1024; == 1024) ...

which doesn’t compile.

The compiler doesn’t complain because sometimes you may actually want to add a semicolon (; is called semicolon, not colon, which is :) to your macro.
