Is it a good idea to put all of your includes in one header file?

Question

What is the best practice for C what you put into a C header file?

Is it useful to put all the includes used for a program across multiple source files in one header

Answer 1

Personal preference really... It doesn't matter how it is formatted as long as you are consistent (which makes it easy to read). You could put it all in 1 header file or you can just put it in every file that needs it. It also depends on how other includes are loaded anything that comes after the main doesn't need its includes and so on so using the same header file for ALL your other C files may or may not (depends on compiler) include the same include multiple times.

Edit: I have to agree with Mac too, put it where you use it is a very, very nice thing to do as well
