ok. i'm having trouble understanding how to manipulate my data. this is what i have so far with my program. my input data is coming from two different file. the first file looks like this that has the student ID, last name, first name...
567 white Robert
43 blackBurBn DOnna
etc...
the second file is set up so that the ID number is first with exam(E), number and grade and hw(H), number and score to follow in no particular order and can be dupes for more than once to get all grades. Q signifying end of line...
43 E 1 95 E 2 89 Q
567 E 1 67 H 1 20 H 5 20 Q
43 H 4 15 H 3 14 Q
etc...
this is my program so far...

}i know i have some extra lines and functions here that i just left in but notated that they arent being used at this time. after compiling my program, this is my results...

White, Roberti know that even if it compiles and gives back this data, i am doing it wrong. the first thing i'm trying to figure out is how am i supposed to initialze my homework starting grades so that they are zeroes instead of the my number increment count.
the second thing i'm not understanding is how do i set up my program, once i initialize my data, to know when reading from the second input that 43 = Blackburn, Donna, and to start plugging the appropriate grades in the appropriate slot. i know i'm not the best when it comes to syntax so any modifications/suggestions to make my program more efficient would be greatly appreciated.
