Inline Functions versus Macros

add my commend into the content

1. Inline functions follow all the protocols of type safety enforced on normal functions.
• more safe then the macro, especially, for the type defination.
• for the type check, macro is checked by prepocessor, and inline functions is checked by compilar.
2. Inline functions are specified using the same syntax as any other function except that they include the inline keyword in the function declaration.
• only difference is keyword “inline”
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.
• more variable for arguments
4. There is no risk if called multiple times. But there is risk in macros which can be dangerous when the argument is an expression.
5. functions can include multiple lines of code without trailing backlashes.
6. functions have thier own scope for variables and they can return a value.
7. debuging
