Read from a file

Hello everyone:
I am trying to write a while loop to control reading from a file to an array. The array can only hold ten integers. The file may contain any number of integers with one per line. I need a loop test condition that will read from the file until either the end of the file is reached or the array is full. Here is what I have so far:

Code:

cin >> temp;
arrayIndex = 0;
while ( array index < arraySize ||                           )

{
array[arrayIndex] = temp;
arrayIndex++;
cin >> temp;
}

Can someone help me please?

You can just use the stream cin itself like a boolean expression to determine whether it has reached the end or encountered an error. And any input operation returns the stream, so (cin >> temp) refers to the stream.

So the canonical form of reading integers until the end of stream or error would be

Code:

while (cin >> temp) {
  // do something with temp here
}

That should put you on the right track.
