方幂序列 c+~+
Trigraph Sequences in C++ are the set of three characters starting from double question marks (??). These set of the characters replaces by a single character specified in the below table,
C ++中的Trigraph序列是从双问号( ?? )开始的三个字符的集合。 这些字符集替换为下表中指定的单个字符,
| Trigraph | Replacement |
|---|---|
| ??= | # |
| ??/ | \ |
| ??' | ^ |
| ??( | [ |
| ??) | ] |
| ??! | | |
| ??< | { |
| ??> | } |
| ??- | ~ |
| 三部曲 | 替代 |
|---|---|
| ?? = | # |
| ?? / | \ |
| ?? | ^ |
| ??( | [ |
| ??) | ] |
| ??! | | |
| ?? < | { |
| ??> | } |
| ??- | 〜 |
Syntax:
句法:
??=define
Becomes,
#define
Trigraph序列的C ++程序 (C++ program of trigraph sequences)
// C++ program to demonstrate the example
// of trigraph sequences
# include <iostream>
using namespace std;
??=define MSG "Hello, world!"
??=define COUNTRY "INDIA"
int main()
??<
cout << "My message is: " << MSG << endl;
cout << "My country is: " << COUNTRY << endl;
return 0;
??>
Output:
输出:
My message is: Hello, world!
My country is: INDIA
