Syntax to include any Header file, irrespective of its type Introduction to "stdio.h"Ī header file in C is the one in which it contains function declarations/ definitions, variables and macro definitions to be shared between several source files and has a filename with extension ".h". In this article we are discussing in brief up on the "Header Files Inclusion" section for "stdio. It also consists of body of the function inside which we include our custom logic.
In C program, the program execution starts from main() and its signature is having a return type of integer(from our example). And these Header files may also contain macros and variables specific to the library. The prototype or signature and data definitions of these functions are present in their respective header files.
Basically these functions are called as "inbuilt" or "built-in" functions in C programming. End of Scope/Body of Function main()įrom the above example, Generally Header Files consists many features so that, by including or importing the Header Files( "stdio.h") we can consume the functionality. Int main(void) // Main Method Declaration Let us consider the following example, // Structure of C Program We'll discuss the Structure of C program with a small example code. In short, stdio.h stands for standard input and output and is used to provide utilities supporting input and output features in C Programming Language.įollowing are the sections of this article:. Later, we look into specific attributes of Header file like - Built-in functions, Library Variables and Macro. Secondly, we discuss up on the Introduction to Header file(as we stick specific to "stdio.h"). Firstly we'll start by explaining about the structure of C program. In this article we'll discuss a bit about the Standard Header Library "stdio.h". And for most of us, It is the entry point or basic to learn other programming languages. We all know that C is a general-purpose and Procedural programming language.
