Macro- does not involve in compilation if there is any
logical error also just replaces the code
inline- look like function, but control doesn't goes to
fucntion and execute, it simply replaces the code like
macro but involves in compilation.

Answer / rahul sharma
Macro is a must do thing whearas inline is a hint to the compiler. he may choose not to inline if the function seems complex (it uses recursion or many loops)
Macro can have side effects e.g. the typical
SQUARE(++i); problem
but these problem are not there in inline functions

Answer / vishal
1> Macros are always expanded by pre-processor, whereas compiler may or may not replace the inline definitions. You cant force compiler to make a function inline. It is purely compiler based decision.
2> Debugging macros is also difficult.
3> Expressions passed as arguments to inline functions are evaluated once. In some cases, expressions passed as arguments to macros can be evaluated more than once.
