c++ - How do you stop reading integer from text file when encounter negative integer?

Im trying to write a simple code in c++ to read in integer from a text file, the code should stop reading when it encounter a negative integer. The txt file contains 1 positive integer on each line, and the last line is a negative integer.

My code right now using eof, and it reads in negative integer also, which I dont want.

while(!inFile.eof())
{
    inFile >> data;
}

Text file

10
22
33
34
-1   

Thanks in advance :)

Answer

hmm..

int data = 0;
while(inFile >> data && data >= 0) 
{
 // do stuff with data.
}
