...this is how the program should work (a pain in the ass to explain here):

1. Program will ask for selection (1 to display list of Russian planes, 2 for US planes, 3 to close the program)



2. Inputting either of the first two numbers will display the respective lists





3. Entering one of the indicated keys should display the selection's information which in this case, didn't... shady.gif



Now, HERE'S THE PROBLEM, as mentioned above, when I input a correct key, in this case "1" for "MiG-29", it displays an invalid input message as if I've typed in a wrong key instead of diplaying the info, which should be:

QUOTE
MiG-29 Fulcrum

The Mikoyan MiG-29, NATO codename Fulcrum, is a Soviet multirole
fighter aircraft developed in the 1970s. It became a deadly adversary
against its US counterparts, the F-16 and the F-15. It also saw service
with other nations, and evolved into more sophiscated variants like the MiG-35.

I had a really rough time trying in finding out the problem, need help! smile.gif

I presume you're required to write this in C, right?

If you're not you could write it in batch with a quarter of the code.
partyzanPaulZy
Are you sure about that getch() ?

I don't use conio.h either gotoxy, but I can't find reference on that function on www.cplusplus.com.

... I'm not sure those gotoxy were neccessary anyways.


I would use different functions (dunno about that gotoxy positioning function),
but I think you have been mismatching variables: choice instead of ret, air1 or air2.

Look on switches in your code, I don't know if you have right variables there...
CODE
void mig29(void)
     {
      int ret;
      clrscr(); //you have cleared the screen so why those gotoxy functions ?
      printf("  MiG-29 Fulcrum \n");
      printf("\n");
      printf("The Mikoyan MiG-29, NATO codename Fulcrum, is a Soviet multirole\n");
      printf("fighter aircraft developed in the 1970s. It became a deadly adversary\n");
      printf("against its US counterparts, the F-16 and the F-15. It also saw service\n");
      printf("with other nations, and evolved into more sophiscated variants like the MiG-35.\n");
      printf("\n");
      printf("Press 1 to go back\n");
      printf("\n");
      printf("Current selection: ");
      ret = getchar();

     switch(ret) // haven't you mismatched vars ret and choice ?

      {
      case 1: clrscr();
          rus();
          break;
      default: gotoxy(2,12);
           printf ("Invalid key!");
           break;
      }
      //getch(); //ok, I don't know what this one does
     }

This is why one uses object oriented languages. Sorry I can't help you though. I know C++ and Java.

CODE

cprintf("Current selection: ");
scanf("%d",&air1);

switch(choice)


This is located in the rus() function. The error is caused because you read in a choice into the variable but you are, from what i can tell, using a different variable that was not given any value. that would give you the first error. I don't know if you have any other errors because I don't have any way of test running the code.

Actually there are rus() and usa() functions with this bug, fix them and it should work properly. wink.gif

now I am gonna back to my school project around primitive server-client file transfer...

So far that was the only errors I encounter, i.e. properly displaying the corresponding pages as I've explained on my first post.
