Escape Sequences
Sometimes, it is necessary to use characters that cannot be typed or has special meaning in C++ programming. For example, newline (enter), tab, question mark, etc.
In order to use these characters, escape sequences are used.
Escape Sequences Characters
\b : Backspace
\f : Form feed
\n : Newline
\r : Return
\t : Horizontal tab
\v : Vertical tab
\\ : Backslash
\' : Single quotation mark
" : Double quotation mark
\? : Question mark
\0 : Null Character
Characters
A character literal is created by enclosing a single character inside single quotation marks. For example:
'a', 'm', 'F', '2', '}' etc.
Floating-point Literals:
A floating-point literal is a numeric literal that has either a fractional form or an exponent form. For example:
-2.0
0.0000234
-0.22E-5
Integers:
An integer is a numeric literal(associated with numbers) without any fractional or exponential part. There are three types of integer literals in C programming:
decimal (base 10)
octal (base 8)
hexadecimal (base 16)
For example:
Decimal: 0, -9, 22 etc
Octal: 021, 077, 033 etc
Hexadecimal: 0x7f, 0x2a, 0x521 etctotal contributions (5)
String Literals :
A string literal is a sequence of characters enclosed in double-quote marks. For example:
"good" : string constant
" " : null string constant
" " : string constant of six white space
"x" : string constant having a single character
"Earth is round\n" : prints string with a newline
