Program won't read data from text file

[vputman2009]

//I am having problems with reading the data from the file. It always outputs //"Invalid file name". I also am having problems with my print_Saverage //function. It always evaluates as true and just prints a 1 instead of the //average of the 5 scores.

You're trying to open a file called "filename". You need to specify the file extension (i.e. txt, dat) and change it to "filename.type".
