Escape Sequence In Dev C%2b%2b

  1. Escape sequences in C Programming are character combinations which comprise a backslash ( ) followed by some character. They give results such as getting to the next line or a TAB space. They are called escape sequences since the backslash causes an “escape” from the normal way characters are interpreted by the C compiler.
  2. Commonly used escape sequences are n, t and a. The escape sequences are enclosed in single quotes. Is a new line character and helps in transferring control to the next line.

The following table describes simple escape sequences with a single action command directly after the ESC character. These sequences have no parameters and take effect immediately. All commands in this table are generally equivalent to calling the SetConsoleCursorPosition console API to place the cursor.

In C programming language, there are 256 numbers of characters in character set. The entire character set is divided into 2 parts i.e. the ASCII characters set and the extended ASCII characters set. But apart from that, some other characters are also there which are not the part of any characters set, known as ESCAPE characters.

List of Escape Sequences

Some coding examples of escape characters

// a escape sequence
intmain(void)
printf('My mobile number '
return(0);

Output:

// escape sequence
intmain(void)
// - backspace character transfers
// or without deleting on different
printf('Hello GeeksF');
}

Escape Sequence In Dev C%2b%2b
//escape sequence
intmain(void)
// Here we are using, which
printf('Hello');
return(0);

https://ameblo.jp/dradunsmoothin1980/entry-12632551491.html. Output:

// escape sequence
int
{
// a horizontal tab character.
// between two words.
return(0);

Output:

The escape sequence “ ” is very frequently used in loop based pattern printing programs.

Escape Sequence In Dev C 2b 2b 4

// v escape sequence
intmain(void)
// Here we are using v, which
printf('Hello friends');
printf('v Welcome to GFG');
return(0);

Output:

// sequence
intmain(void)
// Here we are using , which
printf('Hello fri ends');
}

Output: (Depend upon compiler)

// escape sequence to print backslash.
intmain(void)
// Here we are using ,
// means and.
return(0);

Escape Sequence In Dev C 2b 2b 3

Output: (Depend upon compiler)

Explanation : It contains two escape sequence means it after printing the the compiler read the next as as new line character i.e., which print the GFG in the next line

// sequence/ and ' escape sequence to
#include <stdio.h>
{
printf(' Hello Geeks');
}

Output:

// ? escape sequence
intmain(void)
// Here we are using ?, which is
// in the early of C programming. But
printf('??!');
}

Output:

#include <stdio.h>
{
// each O in 'OOO' is one to three octal
char* s = 'A725';
return0;

Output:

Escape Sequence In Dev C 2b 2b 1b


Explanation : Here 000 is one to three octal digits(0….7) means there must be atleast one octal digit after and maximum three.Here 072 is the octal notation, first it is converted to decimal notation that is the ASCII value of char ‘:’. At the place of 72 there is : and the output is A:5.

// sequence
intmain(void)
// We are using xhh escape sequence.
// digits(0.9, a.f, A.F).
printf('%s', s);
}

Output:

Escape Sequence In Dev C 2b 2b 1

Explanation : Here hh is one or more hexadecimal digits(0….9, a…f, A…F).There can be more than one hexadecimal number after x. Here, ‘x4a’ is a hexadecimal number and it is a single char. Firstly it will get converted into decimal notation and it is the ASCII value of char ‘J’. Therefore at the place of x4a, we can write J. So the output is BJ.
