Function-like macros can take arguments, just like true functions. To define a macro that uses arguments, you insert parameters between the pair of parentheses in the macro definition that make the macro function-like. The parameters must be valid C identifiers, separated by commas and optionally whitespace.
What is macro and its uses?
A macro is an automated input sequence that imitates keystrokes or mouse actions.

| Macro | Function |
|---|---|
| Macro is Preprocessed | Function is Compiled |
| No Type Checking is done in Macro | Type Checking is Done in Function |

| Macro | Function |
|---|---|
| Macro does not check any Compile-Time Errors | Function checks Compile-Time Errors |
Is it better to use a macro or a function?
Macros have the distinct advantage of being more efficient (and faster) than functions, because their corresponding code is inserted directly into your source code at the point where the macro is called. There is no overhead involved in using a macro like there is in placing a call to a function.
What are the advantages of a macro over a function?
Hence, The advantage of a macro over an actual function, is speed. No time is taken up in passing control to a new function, because control never leaves the home function. The macro just makes the function a bit longer.
