Thread: Searching a file for a String Occurence

Okay, I can't read anymore about file I/O.

I have the follow class:

Code:

class Student
{
private:
    std::string studentName;
    int numberDaysPresent;
    int numberDaysAbsent;
    int totalDaysOfClass;
    double currentGrade;
}

I read the data in from a comma delimited text file, and create 543 Student objects that contain that data.

What I want to do now is search a different data file for all occurences of Student[x].studentName. But I do not want to load the other file completely in memory because it contains 11000 lines of data (and takes forever to load) in the following comma delimited format:
DATE OF CLASS, STUDENT NAME, CLASS PARTICIPATION GRADE, QUIZ GRADE.

I have been chewing on this one for several days, and haven't been able to figure it out. Any suggestions would be greatly appreciated.

Cheers!

EDIT:
I then want to grab just the data from the file that relates to the matched student and assign it to the following class:

Code:

class OldStudentData
{
    std::string dateOfClass;
    std::string studentName;
    double participationGrade;
    double quizGrade;
}
