The C compiler is accompanied by a number of useful functions and macros called the C standard library. These functions are defined in standard-library header files. To use the C standard-library functions, we simply include the appropriate header into our program. Here are some of the C standard-library headers:

Available in all C standards:
<assert.h>	Assertion macros
<ctype.h>	Utils for individual characters
<errno.h>	Macros reporting error conditions
<float.h>	Floating type limits
<limits.h>	Sizes of basic types
<locale.h>	Localization utils
<math.h>	Math functions ...
