Having getche() recognize tabs, enter, and backspace.

I'm trying to write a program that will recognize when you press the tab, enter or backspace keys, and display the name of the key pressed, instead of actually doing a tab, enter or backspace. I've got everything figured out except how to recognize the keys. Can somebody help me out?


Note: I'm extremely new to C.

Hi there,

first of all, you can use a conditional statement to recognize if any of the above keys have been entered....

Code:

---

  ch = getche();
  if(ch == '\t') { /*do something*/ };

---

secondly, as tab, backspace, are whitespace characters you will not be able to display on the screen these characters using the conventional method of printf("%c", ch); Alternatively you could use their hexadecimal equivalent to display the character entered.

Code:

---

  ch = getche();
  if(ch == '\t') {
    printf("%x", ch)
  };

---

lastly, if your compiler fully implements the conio.h libraray you could use the function getch() instead of getche(); getch doesnot echo the input character to the display.

Code:

---

  ch = getch();
  if(ch == '\t' || ch == '\b' || ch == '\r' || ch == '\n')
 {
    printf("%x", ch)
  };

---

Thanks for your help :)

You could also use isspace() to check for these characters, with the exception of '\b', which is not considered whitespace.

Quzah.
