qwerty/azerty keyboard type problem + question about loop.

Well, first of all I'd like to ask how to make the program lookfor the keyboard type (azerty or qwerty) because since I have an azerty one, when I type q it shows up as a and so on...how can I solve this problem?
Also I've written a morse translation program (the idea is from someone else, sorry, but it is just to exercise myself), and I have a problem, each time a letter is translated into morse, I'd like it to rework the whole system so if you type a letter and press enter it continues to give you the answer and then you can again until ESC is pressed, how do I do that? It's the first time I need to apply a loop to several actions, so it's hard. Here's the code:

Code:

---

#include <iostream.h>
#include <conio.h>
#include <time.h>
#include <stdlib.h>
#include <windows.h>

void main()
{
  char morse;
  cout<<"Welcome to the Morse Translator (c) v1.0 created by Patrick Marinkovic.";
  cout<<"To find  how a letter of the alphabet is spelt in the Morse language, please type a      letter and press Enter. Whenever you wish to exit, press ESC:";
  cin>>morse; //now will start the answers code
  if(morse=='a')
  {
  cout<<"._ is a. If you wish to translate another letter please type it and press Enter,otherwise press ESC to exit:";       
  }
  else if(morse=='b')
  {
  cout<<"_... is b. If you wish to translate another letter please type it and press Enter,otherwise press ESC to exit:";
  }
  else if(morse=='c')
  {
  cout<<"_._. is c. If you wish to translate another letter please type it and press Enter,otherwise press ESC to exit:";
  }
  else if(morse=='d')
  {
  cout<<"_.. is d. If you wish to translate another letter please type it and press Enter,otherwise press ESC to exit:";
  }
  else if(morse=='e')
  {
  cout<<". is e. If you wish to translate another letter please type it and press Enter,otherwise press ESC to exit:";
  }
  else if(morse=='f')

  }

  }
  else if(morse=='p')

  cout<<"._ _. is p. If you wish to translate another letter please type it and press Enter,otherwise press ESC to exit:";
  }
  else if(morse=='q')
  {
  cout<<"_ _._ is q. If you wish to translate another letter please type it and press Enter,otherwise press ESC to exit:";
  }

  }
  else
  {

Hope anyone knows the answer.

I wrote a similar program a few days ago.
I'll post the code once I get home.

meanwhile, if you want to check the EXE version
go to http://mahurshi.tripod.com/software.htm
(and look for MORSE)
[can't give you direct link because of tripod restrictions]

But I did not use the ESC etc..

here's how the ESC usually works

while (kbhit() != 27)
{
//place your code here
}

so this one runs as long as ESC (code 27) is not pressed.

I think the keyboard layout is an OS issue. You have to configure that in you OS.

void main is wrong - use int main(void)

Is stead of if...elseif...elseif...elseif... you can also use the switch statement (or use an array).

Here's an example:

Code:

---

#include <stdio.h>
#include <stdio.h>
#include <conio.h>

int main(void)
{
        char morse;

        printf("Enter character or ESC to quit: ");
        while((morse = getch()) != 27)
        {
                printf("%c\t", morse);
                switch(morse)
                {
                        case 'a': printf(". _"); break;
                        case 'b': printf("_ . . ."); break;
                        case 'z': printf("_ _ . ."); break;
                        default: printf("invalid character");
                }
                printf("\nEnter character or ESC to quit: ");
        }
        return 0;
}

I'm sure there is some kind of define for the Escape character but I can't find it.

Thanks both of you!µ
moonwalker, who do you think I got the idea from? And thanks for proposing the code :)
Thanks for pointing that out, Monster, I had kept the void main from a previous program.
I have not yet learned switch neither how arrays work, but thanks, I'll maybe use that way in the next version (that will translate sentences I hope).
I didn't know printf existed in C++!?!?
Here's the code of my program if anyone's interested:

  while((morse = getch()) != 27)

Hope it helps someone :)

Wouldn't it be easier to take the "If you wish to translate another letter please type it and press Enter,otherwise press ESC to exit:" part out of the if/else/if/else/etc. bit and stick it below all of the branching statements, so you only have to have one instance of it?

Yes it's better, thanks!
But since the program is finished, I'll leave it that way.

here's my code, as i promised.... (it doesn't have ESC etc..)

What's the problem?

small glitch... there should have been a '\'

delay also doesnt work with dev c++

this will work for you:

i am attaching the code.... this forum is not printing all characters

see this... you'll understand
