Tips for including headers in c

If we use high level languages and get used to developer environments such as visual studio, eclipse, android studio, inclusion and import are very easy. In order to develop c language in vi environment, basic knowledge about header is required. I hope the following headers and their comments can help you.

Major headers for using standard c libraries
