What is the principle distinction between the function calls and messages?

Question Posted / jagdish kumar


What is the principle distinction between the function calls and messages?..

Answer / Praphull Kumar Mishra

In Objective-C, a function call is a direct invocation of a function using its name, followed by parentheses that contain any required arguments. A message, on the other hand, is a request sent to an object to perform a task or access its instance variables. Messages are sent using square brackets ([ ]) and are used to call methods in Objective-C.
