Escape Sequences

 Sometimes, it is required to use newline, tab, quotation mark etc. in the program which  either  cannot  be  typed  or  has  special  meaning  in  C  programming.  In  such  cases, escape sequence are used. For that incident \n is used for newline. The backslash “\” causes escape from the standard way the characters are interpreted by the compiler.


This escape sequences are only used in printing statements like printf for example: 

printf(“\n Hello \t World!”). 

Table of Escape Sequences:

Escape
Character
\b
Backspace
\f
Form feed
\n

\r
Return
\t
Horizontal tab
\v
Vertical tab
\\
Backslash
\’
Single quotation mark
\*
Double quotation mark
\?
Question mark
\0

Examples created on escape sequence:

#include <stdio.h>
void main(){
printf (“\nHello\nWorld!”);
}
#include<stdio.h>
void main ( ){ 
Comment
printf (“Hello\tWorld!”);
}
#include<stdio.h>
void main(){
printf(“Hello World” \n);
}
o/p: 
Hello
World
O/p: Hello        World!
O/p:  Error
Note: Sequence escape always in between “ double quote”

Note: to print sequence escapes give \\

#include <stdio.h>
void main(){
printf (“Hello \\n World!”);
}
#include<stdio.h>
void main ( ){ 
printf (“Hello \\t World!”);
}
#include<stdio.h>
void main(){
printf(“Hello World” \\n);
}
o/p: Hello \n World
O/p: Hello \t World!
O/p:  Error
Note: Sequence escape always in between “ double quote”

Remaining sequence escape please try yourself.

Why should I learn Computer language (Programming)? And why C language good for beginners?

1. Software is the spirit  ( आत्मा )  of hardware . 2. Just by joining some hardware (Electronics  Components) we can’t make our  Computers, Laptops, Mobiles, Tablets, etc. so programming is essential to make this hardware functional. 3. Program instructs and controls the hardware and C is the very basic language to start. 1. By learning a computer language you'll able to build your own software, OS, Virus, Antivirus. For example, WhatsApp, Hike, Calculator,  Media  Player, Facebook, Twitter. 5. After learning the C language you'll be able to build your own computer applications. 6. C language Helps to learn more advanced languages like Java, Dot Net, MATLAB. because this all language depends upon C language. 7. It is good for starters because it is just like the English language and easy to understand.

Format Specifying in C

  Data Types Format Specify Char %c  or %s Int %d or %i Float %f Using of Variable # include <stdio.h> void main() { int a = 5, b = 7; int c = a+b+3; printf (“C= %d”, c); } # include <stdio.h> void main() { int a = 5, b = 7; printf (“SUM= %d”, a+b); } # include <stdio.h> void main() { char a1 = ‘s’, a2 = ‘g’; printf (“%s%c%s%s”,a1,a2,a2,a1); } O/p: C = 15 O/p: C = 15 O/p: sggs

New trends and advantages of C language.

1. You can program the ROBOTS and  Automatic Running Machines  using C language. click here for more information.  2. For building more advanced  software or  Games you need to  learn more advanced languages like  Visual  Basic,  .NET, JAVA, ANDROID programming which is based on C.  3. To build a website you need only HTML and you can make your own website but for making it more advance you need to learn more web designing languages like CSS, JavaScript, Ajax, PHP and this all languages are very easy to learn if you have some basic knowledge about C. 4. After learning C you will be able to make your own software like Calculator, Games, Embedded Softwares, Compilers.
