A standard header, in C, Objective-C and C++ programming, is a header file that contains common definitions and data structures that all programs may use as required. Also called "include files," header files use the #include preprocessing directive to incorporate them with the program. Header files typically use a .h extension.
Unlike C++, C# is written inline so it does not require header files.
