How can I repeat a menu on wrong input?

Would anyone be able to know a way I can make the program display the menu again to the user when their input is invalid?
Any other than copying and pasting the menu and if statements in the else.

Thanks,

Code:

---

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

int meteorological_module();
int miscelleneous_module();

int main()
{
  int reply_menu1 = 0;
  int items_menu1 = 0;

  clrscr();
  printf(" This Program is still under development\n\n");
  printf(" Here are the menu options that this program offers: \n\n");
  printf(" %d. Select this option to go to the METEOROLOGICAL modules"
            " program\n", 1);
  printf(" %d. Select this option to go to the MISCELLANEOUS modules"
            " program\n", 2);
  printf(" %d. Enter three or a higher number to exit from this"
            " program\n", 3);
  printf(" Choose your option: ");
  scanf("%d", &reply_menu1);

  if (reply_menu1 == 1)
  {
  printf("\n You have chosen for the METEOROLOGICAL program\n");
  meteorological_module();
  }

  if (reply_menu1 == 2)
  {
  printf("\n You have chosen for the MISCELLANEOUS program\n");
  miscelleneous_module();
  }

  if (reply_menu1 == 3)
  {
        printf ("\n Youv'e decided to QUIT, good-bye.");
  }

  else
  {
      printf ("\n Your choice is out of range. Please re-enter, make sure"
              " your input is valid.");
  }
  getch();
  return 0;
}

you can put everything inside a do...while()

Code:

---

int exit=0;
do
{

All your other code here....



printf(" %d. Enter three to exit from this menu"
            " program\n", 3);

if (reply_menu1 == 3)
  {
    exit=1;
  }

} while (exit==0);

the rest of the program here

if reply_menu1 is greater than 3, then the loop repeats itself, and you see the menu again..

hope this helps

Thanks for your reply, but it's no exactly what I'm after.

3 or a higher number should exit from the program immediately, I can do that. However, I want the menu to be displayed again ONLY when the user enters an invalid value, such as a value less than 1 or a letter. from any sub-menu's I want to give the user the choice of returning back to the main menu, so not have the main menu displayed in front of them again when theyv'e inputted something in one of the sub-menus.
Hope you understand, any ideas appreciated.

Anyone got any ideas on this?

Yeah, here's an idea! How about listening to the first reply? Don't tell me you can't figure it out from that.

Code:

---

while something
    while input != valid
        prompt for correct input
        get new input
    do something with the input

They say what seperates man from beast is his thinking ability. I'm not so sure in your case.

Quzah.

just a small tip ... put your menu in a seperate custom function like 'void menu()' to make your code easier to read.
