Program won't output

[DMaguire27]

We have written a program that should create some .txt files, but it is not working right. The program executes properly otherwise; Visual Studio is not giving us any errors.

We're reading two files (Master and Transactions) into separate arrays, creating two new files as the program runs (Error Log and Master2), then reading Master2 into a third array in order to merge it with the original Master to create NewMaster.txt.

None of these files are being created when the program executes (not even empty text files).

Code follows in the first comment.
