Question

Difference between macro and function in C++.

Answer 1

Here is ur answer :-

The basic difference is that function is compiled and macro is preprocessed. When you use a function call it will be translated into ASM CALL with all these stack operations to pass parameters and return values. When you use a MACRO, C preprocessor will translate all strings using macro and than compile.

I hope it helps u dear ☺️....

Macro is pre-processed..
Macros are usually one liner.
Macros are highly recommended for less allocation of memory space.
The main disadvantage of macro is 
no type checking..
