在c ++中，是否有可能/如何在输入后显示控制台输出，在同一行上，在给出用户输入之前？

Question

In C++, when writing to and taking information from the console using cout / cin, is it possible to do something like

ENTER YOUR DATA HERE --> __ <-- ENTER YOUR DATA HERE

With the user input cursor where the underscores are located, and output located on either side of the cursor, and then the user's typed input appearing between those two bits of output before being returned to cin?

If so how would I got about doing that?

I hope that between my title and explanation here that it's clear what I'm asking, if not I can try to explain further.

Ideally I'd like to do this using iostream / cin & cout, because those are what I've used in the past. If the solution is to use... printf or similar I'll do that but may need a bit of additional explanation since I'm not really experienced in using that for output.

NOTE: I tried to find an answer for this problem and I can't say for sure that there wasn't one, it was mostly just a matter of finding a huge amount of other input/output-related questions.

EDIT: This is using the DOS shell on Windows 7, compiling from the Windows Visual Studio 2012 command-line compiler.

Answer 1

If Windows, use the Console API. http://msdn.microsoft.com/en-us/library/windows/desktop/ms682073(v=vs.85).aspx

If Linux, use the curses library: http://en.wikipedia.org/wiki/Ncurses

If you are using windows you have the option to use the conio.h.

#include<iostream.h>
#include<conio.h>

int main()
{
    clrscr();
    gotoxy(5,3);
    cout<<"HELLO WORLD";
    gotoxy(60,10);
    cout<<"HELLO WORLD";
    gotoxy(35,20);
    cout<<"HELLO WORLD";
    getch();
    return 0;
}

If you wish to use ANSI libraries only, you can try to take a look at this discussion: http://www.cplusplus.com/forum/lounge/78225/

In both cases all you have to do is print the first text, then use gotoxy, then you print seconde text, gotoxy again where you want the input to happens, and read the user input.
