Reading, converting, and outputting strings

[soccer5]

I am trying to complete this assignment and I am having some issues. If someone could just point out whats going wrong I would greatly appreciate it. Below are the instructions for the assignment, then the input file, and my failed attempt.


You are given a file consisting of students’ names in the following form: lastName, firstName middleName. (Note that some students may not have a middle name.) Write a program that converts each name to the following form: firstName middleName lastName. Your program must read each student’s entire name into a variable and must contain a function that takes as input a string, consisting of a student’s name, and returns a string consisting of the altered name.
• Use the string function find to find the index of ,
• the function length to find the length of the string
• the function substr to extract the firstName, middleName and lastName.

Output the altered name into a file. This program has no user interface.

getline(inFile, fullName);
lName = fullName.find(",");
lastName = fullName.substr(0, lName);
midName = fullName.length();
firstName = fullName.substr(lName + 2, midName);
cout << firstName << " " << lastName << endl;
outFile << firstName << " " << midName << " " << lastName << endl;
}
while (inFile.eof() == false);
inFile.close();
}

What exactly is going wrong? Be specific. If you haven't yet, you can always use cout or asserts to help aid yourself in finding bugs.
