Macro vs inline

This page on Macro vs inline describes difference between Macro and inline. Both are used to avoid burden of calling the functions.

Macro is expanded by the compiler while inline functions are parsed by the compiler.

MACRO is implemented with the use of C++ preprocessor directive, while Inline functions by inline keyword.

#define square(x) (x*x)
int z=4;
int J=square(z);

Wherever in the C program square(x) comes it is replaced by x*x, hence it is prone to errors.

Inline functions evaluate argument once,and hence removes all the macro errors.
