Introduction To "C" Language


Basic Introduction:-


Dennis M. Ritchie to develop the UNIX operating system at Bell Labs. C was
originally first implemented on the DEC PDP-11 computer in 1972.
In 1978, Brian Kernighan and Dennis Ritchie produced the first publicly available
description of C, now known as the K&R standard.
The UNIX operating system, the C compiler, and essentially all UNIX application
programs have been written in C. C has now become a widely used professional
language for various reasons:
1. Easy to learn
2. Structured language
3. It produces efficient programs
4. It can handle low-level activities
5. It can be compiled on a variety of computer platforms

IMPORTENT FACTS ABOUT C:-

*) C was invented to write an operating system called UNIX.
a) C is a successor of B language which was introduced around the early
   1970s.
b) The language was formalized in 1988 by the American National Standard
   Institute (ANSI).
c) The UNIX OS was totally written in C.
d) Today C is the most widely used and popular System Programming
   Language.
e) Most of the state-of-the-art software have been implemented using C.
f) Today's most popular Linux OS and RDBMS MySQL have been written in
    C.

WHY WE STUDY ABOUT "C":-

C was initially used for system development work, particularly the programs that
make-up the operating system. C was adopted as a system development
language because it produces code that runs nearly as fast as the code written
in assembly language. Some examples of the use of C might be
1.Operating Systems
2.Language Compilers
3.Assemblers
4.Text Editors
5.Print Spoolers
6.Network Drivers
7.Modern Programs
8.Databases
9.Language Interpreters
10.Utilities

Calling Method Of Function In C Language

Calling Method In C Language:- As We Already See That Any Function has Some Arguments Or void If We Use Variable As Argument Then It Is Called FORMAL PARAMETERS. *Formal parameters behave like other local variables inside the function  and are created upon entry into the function and destroyed upon exit. In C Language there are two ways in which arguments can be passed to a function:- 1)Call by value:-      (using value) 2)Call by reference:-  (using pointer) Now We Will See One By One These Arguments By Taking Suitable Example: 1)Call by value:-  *In This Method actual value copies to formal parameter: *Due To That changes made to the parameter inside the function  have no effect on the argument. This will cleared by following example:- Example Program:- //in this program we swap two variable using third variable: #include <stdio.h> /* function declaration */ void swapping(int a, int b); int main () { /* local variable definition */ int x =...

Types Of Array In C language

Two Dimensional Array :- * It Is The Combination Of Two One Dimensional Array * It Is Used To Implement Matrix Operation . *A two-dimensional array can be considered as a table which  will have 'a' number of rows and'b'number of columns. Declaration Of Two Dimensional Array:-   data_type Array_name [size of row][size of column]; For Example:- int matrix[3][4]; in above example we will store a matrix of 3*3. This Will Cleared From Following Figure:- *It can be represented a[i][j].where i and j represents  row and column respectively. Initialization Of Two Dimensional Array:- let us consider an array "float a[3][3]"then it will be initialized float a[3][3]={                {1.2,2.3,4.3} //initializers for row indexed by 0                {2.1,2.2,2.3} //initializers for row indexed by 1                {3.1,3.4,3.6} //initializers for row indexed by 2 ...

Basic Syntax Of "C" Language

1).Tokens In C Language:- A C program consists of various tokens and a token is either a keyword, an identifier, a constant, a string literal, or a symbol. For example, the following C statement consists of five tokens:        printf("Hello, World! \n"); 1.printf 2.( 3."Hello, World! \n" 4.) 5.;(semicolon) Let Us Describe about these Tokens One By One:- A.) Semicolons:- the semicolon is a statement terminator. That is, each individual statement must be ended with a semicolon. It indicates the end of one logical entity. For Example: printf("Helo"); getch(); Given Above Is Example Of Termination Of Two Statements. B.)Comments:- Comments are like helping text in your C program and they are ignored by the compiler. They start with /* and terminate with the characters */ as shown below: /*This Is My First Program*/        OR We can use double slash(//) for comment one line as:- //this is My First Program C.) Identifiers:- A C identifier is a name used ...
