c语言字符集的有效集特殊字符（中英对照）

c语言 字符集 特殊字符

Every language has the set of the characters which are used to form a sentence to write a program/code, we cannot use any character except the valid set of the characters defined by the programming language.

每种语言都有一组用于构成编写程序/代码的句子的字符&＃xff0c;除了编程语言定义的有效字符集外&＃xff0c;我们不能使用任何字符。

C字符集 (C character set)

Similarly, C programming language also has a set of characters, which are used to form a C language statement.

同样&＃xff0c;C编程语言也具有一组字符 &＃xff0c;这些字符用于形成C语言语句。

C programming language character set contains the following characters i.e. following are the valid character set in C programming language,

C编程语言字符集包含以下字符&＃xff0c;即以下是C编程语言中的有效字符集 &＃xff0c;

特殊的角色

1) Alphabets

1)字母

C programming supports all the uppercase and lowercase alphabets.

C编程支持所有大写和小写字母。

Uppercase alphabets: A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, ZLowercase alphabets: a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z

So, there are total of 52 alphabets (all uppercase and lowercase) are allowed in C programming language.

因此&＃xff0c;在C编程语言中&＃xff0c;总共允许使用52个字母(全部大写和小写)。

2) Digits

2)数字

C programming supports all digits from 0 to 9, which are used to represent/construct a numeric value/expression or digits can also be used to define an identifier.

C编程支持从0到9的所有数字&＃xff0c;这些数字用于表示/构造数字值/表达式&＃xff0c;或者数字也可用于定义标识符。

Digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

So, there are total 10 digits (all digits) are allowed in C programming language.

因此&＃xff0c;C编程语言中总共允许10个数字(所有数字)。

3) Special characters

3)特殊字符

There are some of the special characters, which are used for special purposes (like mathematical, logical operations, etc), or to define an identifier in a batter way (like underscore to construct a long variable name, etc).

有一些特殊字符&＃xff0c;用于特殊目的(例如数学&＃xff0c;逻辑运算等)&＃xff0c;或以连击方式定义标识符(例如下划线以构造长变量名等)。

In C programming language, there are following special characters:

在C编程语言中&＃xff0c;有以下特殊字符&＃xff1a;

~ &＃96; ! &＃64; # $ % ^ & * ( ) _ - &＃43; &＃61; | \ { } [ ] : ; “ ‘ , . ? /
