掌握C语言划横线技巧，轻松实现文本高亮排版

作者：用户RJGX 更新时间：2025-05-29 08:29:12 阅读时间： 2分钟

在C语言编程中，实现文本的高亮排版是一个常见的需求，尤其是在文本编辑器或者命令行界面程序中。以下是一些使用C语言实现文本划横线高亮排版的技巧和方法。

1. 使用ANSI转义序列

ANSI转义序列是一种广泛使用的字符序列，可以用来在支持ANSI转义序列的终端中改变文本的显示属性。以下是一个使用ANSI转义序列为文本添加下划线的例子：

#include <stdio.h>

int main() {
    printf("\033[4m文本高亮\033[0m\n"); // \033[4m 开启下划线，\033[0m 重置所有属性
    return 0;
}

在上面的代码中，\033[4m 用于开启下划线，\033[0m 用于重置文本的所有属性（包括下划线）。

2. 使用终端库函数

如果你的程序需要运行在支持POSIX标准的系统上，可以使用termios和ioctl等库函数来控制终端的属性。以下是一个使用termios库函数设置终端属性并添加下划线的例子：

”`c #include #include #include

void enable_underline() {

struct termios ttystate;
tcgetattr(STDOUT_FILENO, &ttystate);
ttystate.c_lflag |= ECHO | ISIG;
ttystate.c_lflag &= ~(ICANON);
ttystate.c_cc[VMIN] = 1;
ttystate.c_cc[VTIME] = 0;
ttystate.c_ostate &= ~OPOST;
ttystate.c_cc[ONLRET] = 0;
ttystate.c_cc[OLCUC] = 0;
ttystate.c_iflag &= ~(IXON | IXOFF | IXANY);
ttystate.c_iflag &= ~(INLCR | IGNCR);
ttystate.c_oflag &= ~(OPOST | ONLCR | OCRNL);
ttystate.c_oflag &= ~(ONOCR | ONLRET);
ttystate.c_oflag |= OLCUC;
