Problem with WHILE loop.

Code:

---

while(grade[i] != -1)
{
                printf("GRADE: ");scanf("%f",&grade[i]);
                i++;count++;
}

---

I don't get a compilation error, but if I enter in -1 as a number the program just continues to ask for the grade over and over again.

Is grade an array of floats or ints?

As you've incremented i, the test within the while won't be looking at the number you've just entered.

You are reading a value into grade[ i ], you then increment i past the read in value, and compare the wrong grade (which is zero)

>>and compare the wrong grade (which is zero)
Where'd you get the idea it's zero? More than likely it's undefined (at least, that's my guess).
