What are Header files?
Header file contains different predefined functions, which are required to run the program. All header files should be included explicitly before main ( ) function.Header files are also called as Pre-compiled header.
Here is some C programming header files ...

<float.h> | | Defines macro constants specifying the implementation-specific properties of the floating-point library. |
<inttypes.h> | C99 | Defines exact width integer types. |
<iso646.h> | NA1 | Defines several macros that implement alternative ways to express several standard tokens. For programming in ISO 646 variant character sets. |
<limits.h> | | Defines macro constants specifying the implementation-specific properties of the integer types. |
<locale.h> | | Defines localization functions. |
<math.h> | | Defines common mathematical functions. |
<setjmp.h> | | Declares the macros setjmp and longjmp, which are used for non-local exits. |
<signal.h> | | Defines signal handling functions. |
<stdalign.h> | C11 | For querying and specifying the alignment of objects. |
<stdarg.h> | | For accessing a varying number of arguments passed to functions. |
