Header file in C and C++. These header files contain the declarations of the functions, types, and macros that are defined in the standard library.

For example, the standard library in C has a header file named "stdio.h" which provides declarations for input/output functions such as printf() and scanf(). Similarly, in C++, the standard library has a header file named "iOStream" which provides declarations for input/output operations using streams.

Other examples of standard library header files in C include "stdlib.h" for general-purpose functions like malloc() and free(), and "string.h" for functions dealing with character strings. In C++, there are many header files in the standard library, such as "vector" for dynamic arrays and "algorithm" for various algorithms like sorting and searching.

Including these standard library header files in a program allows the programmer to use the functions and types defined in the library without having to write the implementation code themselves. This can save a lot of time and effort and can make programs more efficient and reliable.
