Can you have optional parameters in C?

Functions do not accept optional parameters . Even if a parameter has a default values, you have to specify something when you call the function.

The thing with optional parameters is, they are BAD because they are unintuitive – meaning they do NOT behave the way you would expect it. Here’s why: They break ABI compatibility ! so you can change the default-arguments at one place.

Optional parameters are defined at the end of the parameter list, after any required parameters . If the caller provides an argument for any one of a succession of optional parameters, it must provide arguments for all preceding optional parameters.

C does not support optional parameters . Nor does it support function overloading which can often be used to similar effect.
