Concept of API / Libraries

Application Programming Interface (API) is an interface in computer science that defines the ways by which an application program may request services from libraries and/ or operating system.It is a set of routines, protocols and tool for building software applications.
A good API makes it easier to develop a program by providing all the building blocks.
Although APIs are designed for programmers, they are ultimately good for users because they guarantee that all program using a common API will have similar interface. This makes it easier for users to learn new programs.

Concept of  'C' Library
   The C standard library consists of a set of sections of the ISO C standard which describe a collection of header files and library routines used to implement common operations, such as input/output and string handling, in the C programming language.

Following are some important header files :

   Stdio.h, which stands for "standard input/output header" , is the header in the C standard library that contains macro definitions, constant and declarations of functions and types used for various standard input and output operation.
   String.h is the header in the C standard library for the C programming language which contains macro definition, constant and declarations of functions and types used not only for string handling but also various memory handling functions; the name is thus something of a misnomer.

    Function declared in string.h are extremely popular, since as a part of the standard library, they are guaranteed to work on any platform which supports C.
    Math.h is a header files in the standard library of C programming language designed for basic mathematical operation. Most of the functions involve the use floating point numbers. C++ also implements these functions for compatibility reasons and declares them in the header cmath.
