Header files

A file with an extension that has some predefined declarations and definitions is called a header file. Every computer program imports a set of header files to perform common tasks such as getting input, displaying output, and so forth. Every language has different header files (such as C, JAVA, Python, and C++). In this article, header files are explained mainly in the context of the C/C++ language.
