Inbuilt Library Functions- String.h Library, Time.h Library

The string functions require the header file h. This function appends up to n characters from the src string to the end of the dest string, plus a terminating Null-character. The Null-character at the end of string(src) is overwritten with the first character of string(src) (dest).

The header h in the C standard library comprises macro definitions, constants, and declarations of functions and types that are used not only for text handling but also for different memory handling functions; the name is thus a misnomer.

The string. h header contains one variable type, one macro, and a number of methods for handling character arrays.

The data types used in system source code are defined in the /usr/include/sys/types.h file. Because some system data types can be accessed by user code, they can be utilised to improve portability between machines and operating systems.

The length(string) function is the simplest basic example of a string function. The length of a string literal is returned by this function. length("hello world"), for example, would return 11. String functions in other languages may have similar or identical syntax, parameters, or consequences.
