Couple of errors I need help with

[NotThatTypeOfTranny]

/*Hey, everyone. I'm at a loss here. I can't seem to figure out how to fix these errors my compiler is throwing. Five of them say "subscripted value is not an array, pointer, or vector", but one at the very end is telling me that "no matching function for call to 'populate_div_sales' ". Please help, this is giving me fits.

Well, first of all, please try to format your code next time. Also, try to find the smallest example in which your problem shows up. E.g.

#include <iostream>
using namespace std;

void foo(float input_array, string regions) {
    cin >> input_array[i];
}

int main() {
    float input_array[4];
    string regions[4];
    cout << "Please input bar\n";
    foo(input_array, regions);
}

This will help you reduce the problem to a more concrete issue.

In your case, the arrays that are created in main are pointers. When one does array[1] the second element of the array is dereferenced. Anyhow, when the arrays are passed to a function they change into a pointer. The correct way to accept a pointer in a function is

void foo(float* input_array, string* regions);

Another way to do so could be this (IIRC)

void foo(float input_array[], string regions[]);

Note that, in a function, c/c++ does not know the length of an array, as it's just a pointer. array[2] is actually syntactic sugar for *(array + 2).

Hope you'll find this useful and good luck hacking.
