c++ - 如何与ncurses画线？

Question

我知道 C++ ncurses 的基础知识，但我不知道如何在两个坐标之间绘制一条简单的线。

例子:

2------------3

我怎样才能做到这一点？

Answer 1

   int hline(chtype ch, int n);
   int whline(WINDOW *win, chtype ch, int n);

The hline and whline functions draw a horizontal (left to right) line using ch starting at the current cursor position in the window. The current cursor position is not changed. The line is at most n characters long, or as many as fit into the window.

至于角色，您可能需要 ACS_HLINE，但 - 可能也可以……也许更好。
