Introduction to C

C is a programming language developed by "Dennis Ritchie" at AT & T's lab of USA in 1972. It gives us basic programming skills, problem solving technique and concept to write a program. It is very powerful programming language, still today. It is a middle level programming language that is able to manipulate the computer at a low level like assembly language. During the last half of the 1980s, it became the language of choice for developing commercial software. It is the most commonly used programming language for writing system software, though it is also widely used for writing applications. C, and its object-oriented successor C++, are used to write a huge variety of applications and almost all operating systems.

Some of the advantages of C language are:-
  • It provides predefined header files and keywords.
  • It provides declaring different types of data variables.
  • It provides flexibility and simplicity, so it can be easily learned.
  • C provides several language elements that makes interaction with hardware device feasible without compromising their features.
  • It provides facility to use user defined header files.
  • It is used to code the drivers for various operating systems such as windows, unix.
Some of the disadvantages of C language are:-

  • It doesn't provide object orientation.
  • It's doesn't provide rich graphics programming
  • It's code writing is lengthy.

Components of C language

Image
There are five main component of C language :- 1. The character set: Any alphabet ,digit or special symbol ,used to represent information is denoted by character. The character in C are grouped into four categories:- i) Letters A...Z and a...z ii) Digits 0,1,2,.....9 iii) Special Symbol ~ ` ! @ # $ % ^ & * () . < > ? / " : ; { }[ ]. iv) White Space,blank space, Carriage return, form feed, newline, horizontal tab. C uses the uppercase letter A to Z, the lowercase letters a to z, the digits 0 to 9, and certain special characters as building blocks to form basic program elements ( e.g., constants, variables, operators, expressions, etc. Some of the special characters are listed below: + - * ~ % / & ( ) { } [ ] ? " < > ! ; : Most versions of the language also allow certain other characters, such as @ and $, to be included within strings and comments. C uses certain combinations of these characters, such as \b,\n and \t, to represent spe...

Decision making using if statement

Image
The if statement is a powerful decision making statement and is used to control the flow of execution of statements. It's a basically two way decision statement and is used in conjuction with an expression. It's syntax is:- "if(test expression)" It allows the computer to evaluate the expression first and then, depending on condition, it transfers the control to a particular statement. This point of program has two paths to follow,one for the true and other for false condition.As shown in figure:-     Practical examples of if statement:- 1. if(bank balance is < 500)     deposit money 2. if(room is dark)     put on lights The if statement may be implemented in different forms depending on the complexity of conditions to be tested. The different forms of if statements are:- 1.Simple if statement 2.if....else statement 3.Nested if....else statement 4. else if ladder 1.Simple if statement.  The general f...

Backslash character constants

Image
Enclosing character constants in single quotes works for most printing characters.A few , however, such as carriage return, can't be. For this reason, C includes special backslash character constants, so that you may easily enter these special characters as constants. You should use the backslash codes instead of their ASCII equivalents to help insure portability. List of backslash character constants are as follows:- Code Meaning \b Backspace \f Form feed \n New line \r Carriage return \t Horizontal tab \" Double quote \' Single quote \\ Backslash \v Vertical tab \a ...
