c转义字符的使用程序举例

下面是一个简单的C程序，演示如何使用转义字符：

#include <stdio.h>

int main() {
    printf("Hello\tworld!\n");
    printf("This is a backslash: \\ \n");
    printf("This is a double quote: \" \n");
    printf("This is a single quote: \' \n");
    printf("This is a new line: \n ");
    printf("This is a carriage return: \r ");
    printf("This is a form feed: \f ");
    printf("This is a vertical tab: \v ");
    printf("This is a backspace: \b ");
    return 0;
}

输出：

Hello   world!
This is a backslash: \
This is a double quote: "
This is a single quote: '
This is a new line: 
 This is a carriage return: 
 This is a form feed: 
 This is a vertical tab: 
 This is a backspace: 

在这个程序中，我们使用了几个常见的转义字符：`\t` 表示水平制表符，`\n` 表示换行符，`\r` 表示回车符，`\f` 表示换页符，`\v` 表示垂直制表符，`\b` 表示退格符，`\\` 表示反斜杠，`\"` 表示双引号，`\'` 表示单引号。
