So this is a program in c++, here is a code fragment:

cout << "Input file name: ";

cin >> fileName;

inFile.open(fileName);

if(!inFile) {

cout << "Unable to open file " << fileName << "." << endl;

else {

while(inFile) {

Calculate(study, sleep, target, sum, sigmoid, fileName, inFile);

MakePrediction(sigmoid, predict);

DoesItAgree(target, predict, agree);

Output(study, sleep, target, sum, sigmoid, predict, agree);

}

}

I run my code, and I'm reading from a file, let's say the file has 5 lines, so that means the program should do the loop five times, and if it has 10 lines, it should do the loop 10 times, we dont know ahead of time how many lines the file has, but instead it does it one more time, there is something wrong with the loop, how do I fix the loop?
