Question

C++

I need help when I grab data from a text file, and have the float number which is Price (the last getline) return as a float (Only one line of the file is a float Ex: 45.99). Currently with the code I have, its returned the data as an int. Here is a section of my code:

void ReadInventory(book books[], int& size, int MAX_Size)

{
   ifstream dataFile;
   dataFile.open("inventory.text");
   string str;

   if (!dataFile.fail())
   {

       while (dataFile && size < MAX_Size)
       {
           getline(dataFile, str);
           books[size].ISBN = atoi(str.c_str());

           getline(dataFile, books[size].Title);

           getline(dataFile, books[size].Author);

           getline(dataFile, books[size].Publisher);

           getline(dataFile, str);
           books[size].Quantity = atoi(str.c_str());

           getline(dataFile, str);
           books[size].Price = atoi(str.c_str());

           size++;
       }

       dataFile.close();
   }

Or is there somewhere else in this code that I need only one line from the file as a float?!

Explanation / Answer

books[size].Price = atof(str.c_str());
