Not getting proper results.

[learning2019]

So I am about 8 weeks into classes and this is the first time I've really been so confused and frustrated.

The task at hand is as follows:
Program must make use of files, arrays and functions.

The airplane will have 5 rows in the first class section with 4 seats in each row, 2 on each side of the aisle and 10 rows in the coach section with 3 seats on each side of the aisle. The prices for all the first class seats will be the same. The first 5 rows of coach will be more expensive than the last 5 rows. The prices for the seats will be stored in a file called SeatPrices.txt . The program should read these values from the file and store the values in an array of doubles.

This is easily my best work yet - and that's saying something considering how trash it probably is to most experienced authors. Every function (seemingly) works fine except for the most important one, which is gathering the prices from the .txt file and assigning them to the array (seatPrices[]) for use in my main function and otherwise.

I suspect largely that the issue arises somewhere in pricingInformation though from my inexperienced eyes I honestly don't see any glaring defects.
Any help/pointers in the right direction are greatly appreciated,
Thank you wise ones!

(I've had to remove a large chunk of the program due to post size constraints)

There's no need for a function type double to read prices into an array. Just use a type void because the issue is with the return, also you have functions that have no definitions "seatRequests()", "emptyRow()", "emptyPlane()".

[learning2019]

Hi nicholas, thanks for taking the time to reply.
Those functions are there in my full program, this is only a bit of the program (there's a post limit and the full program far exceeded the allowed 9000 characters)

Changing the double back to a void function still gives me the same results, which are no results at all.

void pricingInformation() 
{	
	int count = 0;

	ifstream file("SeatPrices.txt");
	if (file.is_open())
	{
		while (count < 3)
		{
			file >> seatPrices[count];
			count++;
		}
		file.close();
	}
}

Verify that you have been able to open the file and read from it; emit some diagnostic information.

For example:

#include <iostream>
#include <fstream>

// ...
double seatprices[3] ;
// ...

bool read_pricing_information()
{
    const char file_name[] = "SeatPrices.txt" ;

    std::ifstream file(file_name);

    if( file.is_open() )
    {
        for( int i = 0 ; i < 3 ; ++i )
        {
            if( file >> seatprices[i] ) std::cout << "read price " << seatprices[i] << '\n' ;

            else
            {
                std::cout << "failed to read price from file '" << file_name << "'\n" ;
                return false ;
            }
        }

        std::cout << "successfully read prices from file '" << file_name << "'\n" ;
        return true ;
    }

    else
    {
        std::cout << "unable to open seat prices file '" << file_name << "'\n" ;
        return false ;
    }
}

int main()
{
    if( !read_pricing_information() )
    {
        std::cout << "pricing file read failure. quitting program.\n" ;
        return 1 ;
    }

    // ...
}
