[HELP] key press

Code:

---

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

int main()
{
int bal,wit,dep;

printf("enter balance: ");
scanf("%i",&bal);
printf("[W]=Withdraw [D]=Deposit\nPress a key to continue");

/*
if(kbhit()=)
{
}


if(kbhit()=)
{
}
*/

getch();
}

---

I want the user to press either the W or the D key, W for withdrawing, D for depositing. If the user press the W key, it will immediately prompt the user for withdrawal amount (without typing the alphabet W then press ENTER key), how can I do that? Is kbhit() is right function? Btw, I'm learning C on Windows platform.

kbhit, if it exists at all in the system (it is not a standard function, so compiler producers do not need to provide it), will tell you if there has been a key pressed or not (that is, the user "hit" a key on the KeyBoard).

To be standard compliant, use scanf() or getchar().

Correct. If you do not want that, you need to use non-standard solutions. getch() will do it if it, if your code compiles with it.

getch() or getche() worked.

It won't work everywhere. But if ONLY you are going to use this, it won't matter.

It's also in the FAQ:
How can I get input without having the user hit [Enter]?
