Thread: Need Help With C++ Console Homework Project

Howdy.
My C++ teacher asked me to write this console project two weeks ago, I'm still trying but I couldn't write the program and I have just one week left. So I need your help with this, any help will be appreciated.

As you can see at the image above, my teacher asks for a digit extracting program. Sounds easy, right? Yeah, he asked for the same assignment before and I wrote that program. But this time he has strange conditions for the program so I need more experienced coders's help.

My teacher said:
-It needs to work up to 19 digits.
-You need to use 10 semicolons maximum.
-You need to use 3 variables maximum.
-You need to use these ONLY: iostream.h, conio.h, if, getch.
-You MUST NOT use these: for, while, do-while, goto, switch, until, repeat-until, try-catch etc.
Or I'll get an F. Ain't that a ..........?


I've made a digit extraction homework just like the image above only with "if" command. I have used 14 semicolons in total and it supported up to 5 digits. My teacher said he wants 10 semicolons max and 19 digit support or I'll get an F. I tried a lot but couldn't make an application with less semicolons.

Some of you will say this is not the right way to teach C++, and If I want to learn it I need to write this myself. Yeah, you are right and this is not the best way to teach C++. I am aware of it and I want to learn java actually but this is my exam project and If I don't complete it, I will get an F and I won't get any java courses. So I need your help. I know this program is very stupid but I have to finish it.

Notes:
-My teacher said that he used if within an if and wrote it with 7 semicolons in total.
-my classmate said that he found a command and wrote this program with just one variable and 7 semicolons but he doesn't tell me what it is, lol. Screw him.

I hope you guys can help me with that. I'm looking forward to it. Thanks!

Also posted here.

Yeah and also posted to a few other forums. I need every help I can get.

I have to deliver it until this Sunday. I don't see any sign of arrogance. If you are going to help, I'll appreciate it. Thanks.

Think about it.

You've just asked, say, 20 people (since you've posted on "a few other forums") to help you with your problem with no knowledge that other people are helping you with it. Think of the duplication of effort. That's an incredible waste of people's time.

Now that I know you've posted on multiple forums I simply can't help you. It would be a waste of time since you'll presumably get the answer elsewhere.

If you knew the above and did it anyway, then you are simply a bad person. Why are you so special that you deserve to use people like that?

In future, only post on one forum and wait at least an hour (preferably more) before posting on another. It would also be good to let people on the other forums know about the other posts so they can check to see if you've already gotten an answer before putting in their own time.

I have already waited about a week when I posted it on the other forums. The people who helped me tried, but couldn't write the full working program yet so I decided to open another thread here. I thought about posting the solution when I get it to every forum I started the thread, but I still didn't get the program my teacher wanted. Like I told you, It's beyond my level. I didn't know about that cross-posting rule too.

Maybe we should do it, but obfuscate a message that says Sikkirigi didn't write this code. The effort to remove the message would be essentially a rewrite -- or so I would hope.

Na, it seems like he's getting what he wants at one of his many other sites so why bother.

Don't worry, I'm not going to tell my teacher that I made this.

Code:

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

int main()
{
    unsigned long long sayi;

    cout << "Input number: ";
    if (!(cin >> sayi) || (sayi > 99999))
        return !!(cout << "Bad number" << endl);

    cout << sayi;

    size_t div, plus;
    if (plus = div = sayi / 10000)
        cout << " = " << div << "*10000";

    if (div = (sayi = sayi % 10000) / 1000)
        cout << (plus ? " + " : " = ") << div << "*1000";

    if (plus |= div, div = (sayi = sayi % 1000) / 100)
        cout << (plus ? " + " : " = ") << div << "*100";

    if (plus |= div, div = (sayi = sayi % 100) / 10)
        cout << (plus ? " + " : " = ") << div << "*10";

    if (plus |= div, div = sayi % 10)
        cout << (plus ? " + " : " = ") << div << "*1";
        getch();
}

I've made something like this, but as you can see it only works up to 5 digits. I know it can be done this way (and I know this isn't the right way) using : and ? operators but I don't know how to use them. Can you guys help me turn this program to 19-digit supporting program without exceeding the limits my teacher wanted? Thanks.

That's the same code you had about a week ago, what have you tried since then?

Jim

I don't have a luxury like selecting my teachers.
