Homework Function Compile Errors

  #1
Nov 20th, 2008
I am having a problem with a program. I have to create a program with about 8 different functions. Which reads in votes, finds the max, the min, prints the votes, prints the max prints the mid, finds the normalization, outputs how many are below .25 and above .75 and prints the normalization. I've got the program typed but I'm coming up with alot of errors when I compile. Can anyone help me out with these problems?

Thanks, SportsFilmer

Most of the errors you get are typing errors I presume.
For instance, a lot of times you use max or min, where you're giving min or maxloc as argument to the function.
Also some variables are just not declared in a function, remember that each function has it's own variables if they are not declared globally or given as arguments.

EDIT:
a second look at your code tells me that some errors you are having are also forgetting { or not knowing the syntaxis.

Also, in your main function you have this:
cpp Syntax (Toggle Plain Text) 
  1. int main() {
  2.   int maxloc, minloc, range, bottom = 0, top = 0;
  3.   double votes [50], min=votes[minloc], max=votes[maxloc];
  4. }

The problem with this code is that maxloc and minloc are not initialised, which means they can be any value. You have to give them a startvalue, (I don't know how your program works, just corrected some errors quickly)

Hopefully this can help you further...
