At a very minimum check to make sure the file is getting opened...
#include
#include
using namespace std;
float sellingprice (float);

int main()
{

{

Where is file.txt located? If it is NOT in the same directory as your .exe file you MUST include the path to the file.
file.open("C:\\path\\file.txt"); //for example.
I know it has something to do with my file because it works when I put my own numbers in
#include
#include
using namespace std;
