What is the difference between macro and subroutine?..

Answer / paramjeet

Macros can only be used in the program the are defined in
and only after the definition are expanded at compilation /
generation. Subroutines (FORM) can be called from both the
program the are defined in and other programs . A MACRO is
more or less an abbreviation for some lines of code that are
used more than once or twice. A FORM is a local subroutine
(which can be called external). A FUNCTION is (more or less)
a subroutine that is called external. Since debugging a
MACRO is not really possible, prevent the use of them (I?ve
never used them, but seen them in action). If the subroutine
is used only local (called internal) use a FORM. If the
subroutine is called external (used by more than one
program) use a FUNCTION.

What is the difference between macro and subroutine?..

Answer / digant mehta

Subroutine: When a task is to be done repeatedly then it is written as subroutine and this subroutine will be called each time to perform that task.Subroutine program will be stored in some memory location and program control will be transfered to that location each time.where as in macro the number of instructions will be less than subroutine.Here each time u call a macro that set of instructions will be inserted in that location.It is faster than subroutine.But memory requirement is more than subroutine.

We can say that the Header files attached in c and c++ and libraries are are subroutine.
