ncurses：奇怪的行格式

我有这个代码可以与 ncurses 一起使用：

#include <iostream>
#include <string>
#include <fstream>
#include <ncurses.h>
#include <cstdlib>

//char a='a';
int c=0;

bool ex = false;

void mva()
{
    std::cout << "Nothing here yet, move along." << std::endl;
}

void cho()
{
    std::cout << "Choose a valid option noob!" << std::endl;
}

void menu()
{
    std::cout << "Welcome." << std::endl;
    std::cout << "Choose an option" << std::endl;
    std::cout << "1." << std::endl;
    std::cout << "2." << std::endl;
    std::cout << "3." << std::endl;
    std::cout << "4. About" << std::endl;
    std::cout << "5. exit" << std::endl;
}

void pause()
{
    std::cin.get();
    std::cin.ignore();
}

int main()
{
    initscr();
    //clear();
    refresh();
    //system("clear");
    while (ex != true)
    {
        menu();
        std::cin >> c;
        switch (c)
        {
            case 1:
                mva();
                pause();
                system("clear"); //unfortunately, there is no clean variant to this :(
            break;

            case 2:
                mva();
                pause();
            break;

            case 3:
                mva();
                pause();
            break;

            case 4:
                std::cout << "About" << std::endl;
                std::cout << "Programmed by nnmjywg." << std::endl;
                pause();
            break;

            case 5:
                std::cout << "Press enter to exit" << std::endl;
                pause();
                ex = true;
            break;

            default:
                cho();
                pause();
            break;
        }
    }
    endwin();
    return 0;
}

It should work normally, but I'm absolutely baffled when I see this strange line formatting. In addition to that, I also can't see what I enter (with std::cin)

当你的程序调用initscr，ncurses（实际上anycurses 的实现）初始化终端模式以允许自行打印回车符和换行符（“换行符”）。打印换行符不会产生回车符。

但是 iostream 的endl只是换行。当您打印到cout这样，你就会看到楼梯。

当使用诅咒时，cout and cin并不是真正有用。使用getch (or wgetch) 读取输入。另外，使用诅咒echo (or noecho）来控制是否回显您提供的输入getch。诅咒echo没有影响cin（终端同样已设置为不回显输入，并且curses知道何时回显）。
