In a nutshell, you load the file into an array containing one line per
element of the array.
You then work through the array until you find the line you want - if you
know how many lines into the file it is you can of course directly
reference the element (no_of_line -1 because the first array element is
0).
Change the info you want.
Write the changed array back to the file. Coding is left as an exercise
for the student :-)
