I'm supposed to be debugging this source file so that it works properly. There are a total of 6 errors in the file and I've found 4 so far. I can't figure out the last two errors. I have an idea of where the next one is but i can't figure it out. I'll include both source files. The original and the one i've debugged so far. Any help would be appreciated in helping me understand this.

Edit: Last minute edit that I thought might be needed maybe? This is the information that is in the resource file that infile is pulling from.
I wasn't given an explanation for what the program is supposed to do. I was just supposed to debug it. From what I have gathered of the program though it is supposed to take the resource file with those numbers at the bottom of my first post and then spit out a table with a varying ranges and the "# of students" who fall within those ranges according to the numbers read in from the resource file.
Edit: So range 1-24 would be 1 student, 25-50 would be 1 student, 51-75 would be 0 students and so on.
I found another error but can't seem to find the 6th one. The program works fine with 5 errors fixed so I'm assuming there is a logic error somewhere but I can't figure it out because from what I can tell the program is running as intended.

Edit: Just wanted to update this just in case anyone was trying to help me so I could let them know I figured it out aside from the allusive 6th error.
