Question

I need help to fix this program it is written in c++ and needs to run in visual studio. Program uses character strings from a file containing on the first line and answer key and every other line after is the students ID number followed by a space then their test answers.Program currently reads only test answer key and student ID and their answers of second line.  Sample data can be found below.
