1. Inline follows strict parameter type checking, macros do not.

2. Macros are always expanded by preprocessor, whereas compiler may or may not replace the inline definitions.

Error can be checked in inline function during compilation,but in macro no error checking does not occur during compilation.

Macros does not return any return values, so how can compiler judge that the return value should be stored in what type of data. some Compiler directly assign return value without checking data type.

This is not happen with inline function.

1. Macros does not perform any type checking, while inline functions are strict on type checking.

2. Macros have no access to member functions of a class, while member functions can be declared inline.
