C

Official tag for the C programming language.

submission guidelines

Articles and discussions should be directly related to the C programming language. (Not to be confused with C++ (#cpp), Objective C (#objectivec), or C# (#csharp).)

Questions are encouraged! (See the #help tag)

Be careful when criticizing C as a language or platform; most such complaints are old news. Criticisms are permitted, but please keep such discussions polite and objective.
