C 特殊字符
Strings — Special Characters
Because strings must be written within quotes, C will misunderstand this string, and generate an error:
char txt[] = "We are the so-called "Vikings" from the north.";
The solution to avoiding this problem is to use the backslash escape character.
The backslash (\) escape character turns special characters into string characters:
| Escape character | Result | Description |
|---|---|---|
| \' | ' | Single quote |
| \" | " | Double quote |
| \\ | \ | Backslash |
The sequence \" inserts a double quote in a string:
The sequence \' inserts a single quote in a string:
The sequence \\ inserts a single backslash in a string:
Other popular escape characters in C are:
| Escape Character | Result | Try it |
|---|---|---|
| \n | New Line | Try it » |
| \t | Tab | Try it » |
| \0 | Null | Try it » |
