# The C character set

## C character set

A character set in C Programming Language is set of all valid character which is used to form a words, numbers and expression’s in source program.

The character set is fundamental raw material of any language and they are used to represent information like natural language, computer language will also have well defined Character set, that is useful to build the programs.

Now, in this section we learn about the type of the Character set and discuss about all type of it in brief.

V 86 v 118
W 87 w 119
X 88 x 120
Y 89 y 121
Z 90 z 122

### Digit

C programming support 10 digit which are used to construct numerical value.
• Digit 0-9.

0 48
1 49
2 50
3 51
4 52
5 53
6 54
7 55
8 56
9 57

### Special character

! 33 _ 95
@ 64 + 43
# 35 = 61
\$ 36 { 123
% 37 } 125
& 38 | 124
* 42 \ 92
( 40 ; 58
) 41 : 59
39 / 47
34 ? 63
< 60 > 62

### White space
