Incompatible type conversion

[jewel87]

Hello everyone,

I'm working on a function reading data from file.
I am getting an error: E2110 Incompatible type conversion
Here is what i have:

function in the form:

 
void __fastcall TForm1::EnterProductFromFileClick(TObject *Sender)
{
        char ProductName[256]="";
        int ProductID;
        float Weight;
        char WeightCategory[256]="";
        float PriceWithoutVAT;
        float PriceWithVAT;
        char ExpiryDate[256]="";
        int AmountInStock;
        int ReorderLimit;
        char ProductCategory[256]="";
        char InputDate[256]="";
        char DueDate[256]="";
        char Manufacturer[256]="";
        char ManufacturerAddress[256]="";
        char OriginCountry[256]="";
 
        myProductList.getFoodProduct(i)->
ReadDataFromFile(ProductName, ProductID, Weight, WeightCategory,
                                   PriceWithoutVAT, PriceWithVAT, ExpiryDate,
                         AmountInStock, ReorderLimit, ProductCategory,
InputDate, DueDate, Manufacturer, ManufacturerAddress,OriginCountry); 
                    //error in the last line
 

The function itself in class Food:

void Food :: ReadDataFromFile(char *ProductName,int &ProductID, 
                                  float &Weight, char *WeightCategory,
                                   float &PriceWithoutVAT, float &PriceWithVAT, 
                                  char *ExpiryDate, int &AmountInStock,
                                  int &ReorderLimit, char *ProductCategory,
                                   char *InputDate, char *DueDate,char *Manufacturer,
                                   char *ManufacturerAddress, char *OriginCountry)
{
        ifstream inputfile;
        inputfile.open("input.txt");
 
         char check[256]="";
 
             while(inputfile>>check)
              {
                     inputfile>>ProductID;
                     inputfile>>ProductName;
                     inputfile>>Weight;
                     inputfile>>WeightCategory;
                     inputfile>>ExpiryDate;
                     inputfile>>PriceWithoutVAT;
 
                     PriceWithVAT = CalculateVATPrice(PriceWithoutVAT);
 
                     inputfile>>AmountInStock;
                     inputfile>>ReorderLimit;
                     inputfile>>ProductCategory;
                     inputfile>>InputDate;
                     inputfile>>DueDate;
                     inputfile>>Manufacturer;
                     inputfile>>ManufacturerAddress;
                     inputfile>>OriginCountry;
 
                };
        inputfile.close();
 
}
 
 

What is wrong here???

I would suggest using a structure or a class to store information about the product, rather than reams of individual variables. Simply pass an instance of this struct or class by non-const reference to the function which reads the data from the file, or better yet, make that function a member function of the new class.

I am using classes, and this function is a member of class. I have some problem with function call, why does it say Incompatible type conversion??

why does it say Incompatible type conversion??

The error should say what argument is causing the problem. Maybe you could post the error.

There is the problem, it is not saying anything about any types at all, just as it is here:
E2110: Incompatible type conversion

Then I have no idea. I can't even see the line number where the error was to have occurred.
