Breaking while loop with CIN

If I made a while loop like this:

Code:

---

while (seconds > 0) {
          system("CLS");
          seconds = (seconds - 0.1);
          cout << setprecision(1) << fixed << seconds;
          Sleep(100);

---

...how could I set it up so that someone entering a letter below it (yes, I know about string and all that) broke the loop? Right now, I have this within the braces right below Sleep(100)...

Code:

---

      if (letter == "w") {
        level++;
        break;

---

...but it doesn't work.

well if it is a letter
a char should suffice
instead of using the break
use a bool flag.

so
while (seconds >0 && !done)
if(letter=='w')
done = true

Thanks Eman, but your code lacks syntax in several ways (curly braces, etc.).

ha ha it is pseudo code..don't expect me to write it properly

OK, I appreciate the help.
