C++ help

I have been trying for hours to get this thing to work. Im trying to put a little pause in the middle of some text so it doesn't all come at once. It just skips past the pause instead of waiting for the user to press enter.

Here are the files:

main.cpp

Code:

---

#include "library.h"

void main ()
{
        int choice (0);

        while(choice != 3)
        {
                cout << "\n\n\n\n";
                cout <<        "********************\n";
                cout << "**  Project Waya  **\n";
                cout << "********************\n";
                cout << "**    1: Play    **\n";
                cout << "**    2: Load    **\n";
                cout << "**    3: Exit    **\n";
                cout <<        "********************\n\n\n";
                cout << ">";
                cin >> choice;
                cout << "\n\n\n";

                switch(choice)
                {
                case 1:
                        prelude();
                        break;
                case 2:
                        //hmmm....
                        break;
       
                }
        }
        cout << "Thank you for playing Waya. Please play again soon!\n\n";
}

---

library.h

Code:

---

#include <iostream>
using namespace std;

//Protoypes

bool prelude();
bool home();
void wait();

---

prelude.cpp

Code:

---

#include "library.h"

bool prelude()
{
        cout << "Your eyes slowly slide open. You start to wonder what all the commotion in the\n";
        cout << "village is about. Not that the commotion is that out of place, after all in two\n";
        cout << "days you will be fifteen and that of course means everyone in the village will\n";
        cout << "consider to be a man, which means there will be a huge celebration and an even\n";
        cout << "bigger feast. 'They are probably just decorating for the party... but at night?'";
        cout << "you thought to yourself.\n\n";

        cout << "Just as you turn over and close your eyes you hear a scream. Your eyes jolt open";
        cout << "and you see a huge dark silhouette stand over you. Before you can react you get\n";
        cout << "punched right in your temple, your vision goes blurry and you loose\nconsciousness.\n\n";

        wait();

        home();

        return true;
}

---

wait.cpp

Code:

---

#include "library.h"

void wait()
{
        cout << "Press enter to continue.\n";

        cin.ignore;
}

---

Thanks in advance,

C++ has a special function for this: system("PAUSE");

I suggest you use it, its what its there for :wink:

I feel like a retard now...

Thanks for the help, it is fixed. :D

Relies on an external program, not recommended since it'll only work on DOS/Windows and having to load cmd.exe (and ntvdm.exe sometimes) is just an inefficient waste of system resources. "pause" was intended for use in batch files, not as something to be called from other programs which can handle waiting for a single character themselves.

Seems to be one of the many bad habits that these newer C/C++ programmers have gotten into. It all started with one noob "programmer" who couldn't figure out how to do this, asked around, got the system("pause") as a joke answer, then basically propagated it and now almost all the new C/C++ material seem to suggest using it.

I can place this phenomenon as starting around 2001 or so, when I first saw it in some new material.

Use this fragment instead, which was the standard before that happened..

Code:

---

puts("Press any key to continue...");
getchar();

---

To make it easier just define it like this

Code:

---

#define WAIT puts("Press any key to continue..."); getchar();

---

Then write WAIT whenever you need it.

This helped me aswell, im starting to learn C++ now so I will need this :) Thanks.

D'oh :smile: Thank you for correcting me on this one, it would appear I still have a lot to learn when C++ is concerned :icon6:

I tried it username1's way and I still have the same problem its skips every other WAIT, anyway to fix this?

hey username like how you said the same thing to a title about him, yeah thanks for closing it like i asked but surly doesnt look like you suggested him the asking a question section yeah uhm thanks loregoreth btw for your help

i dont know if under win32 theres sleep() function. under gnu/linux I use a function that sleeps the thread for a number of microseconds, and that function uses the select() call. if you are writting a console program, you might find this interesting:

Code:

---

int myprint( char *txt ){
    while ( txt != '\0' ) {
          printf( "%c", txt );
          mysleep( 5000 ); // about 5/1000 seconds
          txt ++;
    }
}

---

of course you have to write the mysleep function. I used printf because im not familiar with cin and cout.

Strange, it worked on all the compilers I've tested:

- Borland Turbo C v2.01
- Borland Turbo C++ v3.xx
- M$ C 6.00a
- M$ C 7.xx
- M$ C 8.xx

Maybe I'd actually read your post if you'd express your thoughts a bit more clearly and used punctuation.

There is. kernel32.sleep(). But, that's not exactly what he's trying to do.

I use Microsoft Visual C++.Net 2003. I think its becuase when I press enter it goes on as if I held enter and skips two or three or the WAITs.

Now it's fine...

If it's your hardware that's faulty, that's nothing to do with the code.

Ok, I found the problem and fixed it.
