Need Help Revising Array program: Visual C++

  #1
Mar 22nd, 2005
i got the program to work without any errors before i started to try to get the sort function to work in the main. function.

I need to get the function call for the sortIndex.cpp to work so i can sort the user output by descending order of profit.
The sort function has 5 arguments and i am getting confused on how to get it to work right.

I also need to get the numbers that print out the Average to have only two places after the decimal. The last problem is getting the columns of numbers in the tables to line up.

The errors im getting are:
G:\CSIS240\LAB 04\main.cpp(115) : error C2660: 'sortIndex' : function does not take 3 parameters i know there are 5 paramaters
sortIndex.cpp
G:\CSIS240\LAB 04\sortIndex.cpp(9) : error C2082: redefinition of formal parameter 'k'


Here is my code:

  1. void sortIndex (int[], float a[], int n, int k)// int[] - a list of indexes that will be sorted with the sort values.
  2. {                                // float [] - the list of values to sort.
  3.                                  // int n - the number of values ; int k - sort type 1. ascending , 2.  descending
Call your function like you've defined it.

Regarding the redefinition... 
void sortIndex (int[], float a[], int n, int k)// int[] - a list of indexes that will be sorted with the sort values.
{                                // float [] - the list of values to sort.
                                 // int n - the number of values ; int k - sort type 1. ascending , 2.  descending

   int m;
   int k = 0, number = j;
Which k is k?
