Unresolved external errors

[thechamp1202]

Hi there. I am trying to do a program for school but am getting 4 unresolved external errors having to do with my function call in the main. Please help for the sake of my grades.







//*************************************************************************************************************************************
// Program: Program 3
//
// Purpose: This program reads in sales data from a text file for all divisions in a company.
//
// Input: The program will read data in via text file
//
// Processing: The program will read in the data supplied via text file. It then will call a function getDivision to read in data for one division.
// The program will then call printDivision to output all of the data read in via a while loop. The function will also call addDivision to add all
// divisions sales amounts. Last, the function printCorpSummarry with print the total sales for each quarter.
//
// Output: The program will output each division with their data, as well as the otal sales per quarter, average sales per quarter, and the
// grand total, highest quarter, and lowest quarter.

code tags <> in the little editor thingy are appreciated in the future.

I see one issue. There is a thing called overloading in c++, where you can have 2 functions with the same name but different parameters, for example:
void foo(int x)
void foo(string s)

you are doing this inadvertently.

void getDivision(Division, ifstream &infile);

…
void getDivision(Division* p2div, ifstream &infile)

a division and a division pointer are NOT the same, so they don't match, and the compiler is confused. While it isn't required, it is very safe and self-defensive coding to just copy the function from the definition (where the code for it is) to make the prototype.

that would give you

void getDivision(Division* p2div, ifstream &infile); //named variables in the header are ok.

Got it, I did that for all of my functions and it works now! Thank you so much!!
