Array question in C++?

Okay, basically I have a grades array which takes 6 grades from a file, like this:





for (int x = 0; x%26lt;6; x++)


{


fin %26gt;%26gt; grades[x];


if (grades[x] %26lt; 0)


{


cout %26lt;%26lt; "Error: Negative Grade detected. Terminating program.";


system("PAUSE%26gt;NUL");


return 0;


}


}





Simple enough, right? Anyway, I'm supposed to submit an error if I have only 5 grades in the input file. Problem is, it just makes my program loop indefinitely. What's a way that I can check to see that the sixth value is a proper grade or not?

Using the %26gt;%26gt; operator returns the input stream. If the input stream has reached the end, then it evaluates to false in a condition test.





Assuming there is nothing in your input file after the grades, you could do something like:





for (int x = 0; x %26lt; 6; x++)


{


if (!(fin %26gt;%26gt; grades[x]))


{


cout %26lt;%26lt; "Error: Less than 6 grades in input file";


system("PAUSE%26gt;NUL");


return 0;


}


if (grades[x] %26lt; 0)


{


cout %26lt;%26lt; "Error: Negative Grade detected. Terminating program.";


system("PAUSE%26gt;NUL");


return 0;


}


}
