How can I restrict the cursor not to go further...i.e. when I carry out the program and the program waits for numbers or chars isertion, I want to allow just a determined number (for instance 4) of digits or chars to be entered. It won't allow me to enter the fifth char and will wait for ENTER.

Thank you in advance, Alexandar

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

int main()
{
   char Text[5];
   int i;
   for(i = 0; i < 4; i++)
   {
      Text[i] = getch();
      putch(Text[i]);
   }
   Text[i] = 0;
   while(getch() != 13)
      ;
   printf("\nYou entered: %s\n", Text);

}

As a side note; one might think that this should do the trick:

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

int main()
{
   char Text[5];
   int i;
   for(i = 0; i < 4; i++)
   {
      Text[i] = getche();
   }
   Text[i] = 0;
   while(getch() != 13)
      ;
   printf("\nYou entered: %s\n", Text);
}

But it does not, all the characteres entered are echoed on screen,
but only 4 put into Text, as if both getch's was getche.
