what is differnence b/w macro & functions



what is differnence b/w macro & functions..

Answer / babitha

macro: one line function;not having any return type and
argument so it would not report error even if any
misbehaves in fnction;not having return statement;
macros would be replaced by that functions/value where ever
macro name presents;if we need any later change in funcions
then modifing only at macro is neccssary, sicne it is
replacing wherever macro name presents.

functions:we would recieve error if the function call and
function prototypes are mismatch;xplicitly it should have
one return statement if the retrun type of fucntion is
aother than void;control from main function would jump to
function defintion of called fucntion if that function is
called rather than replacing the function;it may have moe
than one line function.If we want later change i fucntion
execution,then we need to modify on function prototype(if
modified),fucntion defintion and whereever that function is
called.
