Header file problem "conio+.h"

[shooninjo]

Hello. I got a problem with a header file or library in c++. We are supposed to use this in our c++ course but I dont get it to work. The library name is conio+.h. I have tried codeblocks, dev c++ and visual studio 2010. It does not work and the examples in our programming book is built around gotoxy() and such. Why does it not work? An example:

// lol.cpp : Defines the entry point for the console application.
//

#define _GLIBCXX_FULLY_DYNAMIC_STRING 1
#undef _GLIBCXX_DEBUG
#undef _GLIBCXX_DEBUG_PEDANTIC

#include <fstream>
#include <iomanip>
#include <iostream>
#include <cstdlib>
#include <string>
#include <vector>
#include "stdafx.h"
#include "conio.h"
#include "conio+.h"


using namespace std;


int main()
{
	cout<<"hello";
	getch();
	return 0;
}

The error message from Visual c++:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

I dont know if this will work but here is a screenshot:

I don't remember Windows file names being able to have pluses, nor do I remember there being a conio+ header. :/

Now, it's true, I haven't been on that system in ages. However, I do like to keep an eye on where it's going. :)

What exactly were you hoping to do with that header file?

[shooninjo]

I think it is possible to have pluses now :)

Mainly using the gotoxy() function. The headers code is

For the, this is totaly "mumbojumbo", I dont get it, I only know that there are some uses in it, like gotoxy().

[Stewbond]

I also don't recognize "conio+.h".

How new are you at this? Sometimes in a class for starters, people just add all of the #includes they can because they don't know which functions belong to which headers and this keeps your bases covered.

I suggest omitting conio+.h unless you find that a function you need is not defined. Only then should you worry about it.

I see you are using getch(). This is a member of conio.h, so just make sure you keep that one.

[Albatross]

...that header is definitely conio. I suspect that "conio+" was just the name of the project to re-implement it using WinAPI functions (despite some of the comments and preprocessor directives, I don't see any Macintosh functions there).

Just including conio.h should suffice. ;)

@shooninjo
Move stdafx.h to the very top row, above the #defines. That pre-compiled header HAS to be first, or programs will not compile in MS VC++, and get rid of the #include "conio+.h" . The prgram will compile and run fine. If you're wanting to use gotoXY, here is a small function to make that easier. Put this into your program, the just call it with gotoXY(x,y); // x = column across wanted, y = row down wanted.

HANDLE console = GetStdHandle(STD_OUTPUT_HANDLE);
COORD CursorPosition;

void gotoXY(int x, int y) 
{ 
CursorPosition.X = x; 
CursorPosition.Y = y; 
SetConsoleCursorPosition(console,CursorPosition); 
}

[shooninjo]

To programming as a whole I have been doing things for a while, however to the language c++ I am a new. And I dont get gotoxy() to work with conio.h :( thats my main problem. Is there any other function that is like the same "thing".

Gotoxy() is just what it sounds like, go to cordinates.
