掌握C語言劃橫線技巧，輕鬆實現文本高亮排版

最佳答案

在C言語編程中，實現文本的高亮排版是一個罕見的須要，尤其是在文本編輯器或許命令行界面順序中。以下是一些利用C言語實現文本劃橫線高亮排版的技能跟方法。

1. 利用ANSI本義序列

ANSI本義序列是一種廣泛利用的字符序列，可能用來在支撐ANSI本義序列的終端中改變文本的表現屬性。以下是一個利用ANSI本義序列為文本增加下劃線的例子：

#include <stdio.h>

int main() {
    printf("\033[4m文本高亮\033[0m\n"); // \033[4m 開啟下劃線，\033[0m 重置全部屬性
    return 0;
}

鄙人面的代碼中，\033[4m 用於開啟下劃線，\033[0m 用於重置文本的全部屬性（包含下劃線）。

2. 利用終端庫函數

假如你的順序須要運轉在支撐POSIX標準的體系上，可能利用termios跟ioctl等庫函數來把持終端的屬性。以下是一個利用termios庫函數設置終端屬性並增加下劃線的例子：

”`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);
