Hi!
This is my first post here and I'm not good with english
I hope that you will understand
I'm trying to enter a string with only numbers. I solved this but i dont know how to enable delete (backspace button) ?
I solve and this problem but backspace works (arrow go back) but text are not being deleted?
How can i solve this problem?
Here code example:
C++ Syntax (Toggle Plain Text) 
  1. char backspace=8;
  2. while(1)
  3. {
  4. x=getch();
  5. if (x=='\r') 
  6. {
  7. s[i]='\0';
  8. break;
  9.  
  10. }
  11. if(isdigit(x) || x==backspace) 
  12. {
  13. s[i]=x;
  14. i++;
  15. putch(x);
  16. }
  17. }
