C++ :: Reading Data From A Text File?

Each line of the text file has first name, last name, and a salary. Something along the lines of this:

john doe 4000
bob miller 9000

I want my program to take the first name, last name, and salary of each line and assign them to strings. I have tried this so far:

while (inFile){
inFile >> firstName;
inFile >> lastName;
inFile >> grossPay;
cout << firstName << " " << lastName << " " << grossPay << endl;
}

When it outputs the names and the salary, the last line of the text file gets output twice by the program.
