going by the language of your question seems like i am actually attempting a examination paper


The main advantage of using the macro is the speed of the execution of the program (if macro is not used in the program many times or if the program is small). The main disadvantage of the macro is it increase the size of the program because the pre-processor will replace all the macro name in the program by it actual definition before the compilation  of the program. Another disadvantage is tht since there is very little error checking in macros , a macro if not written  properly can lead to a  program  with fair amount of bigs.
