Exactly

p.s. thanks for being so patient with me.

I apologize if I was unclear. What I meant to say was that I need to search inside the text file (not the disk) and find all instances of the grade that was given by the user then display all matching results.

Sort of:
// what follows is really bad pseudo code

user inputs grade to search for
program searches whatever.txt
displays all matching results.

I am currently working on an assignment for school. I am writing a grade book program. So far I have written code to show all current grades from a file, input new grades to the file and exiting the program. My problem is that I need to search the file for a specified character (the grade) and this has me confused.
How would I go about searching a text file for a grade and displaying only the relevant entries?

Any and all...
