trouble reading file into an array

BrianDehn (38)
This is a struct array and when I try to print out the data stored in it I get the first bookArray[i].item_name and the rest is just repeating numbers. it is TAB delim and since I have to do calculations on price and quantity I had to make those int and double types. When they were string types they read in fine and the output was good. This problem started when I changed them from string to numbers. The function that reads the information into the array is:

1
2
3
4
5
6
7
8
9
10
11
12
13

 int i = 0;
	  while(!infile.eof() && i < MAX_BOOKS)
		 {
				getline(infile,bookArray[i].item_name, '\t');
				getline(infile,bookArray[i].listing_id, '\t');
				getline(infile,bookArray[i].seller_sku), '\t';
				infile >> bookArray[i].price, '\t';
				infile >> bookArray[i].quantity, '\t';
				getline(infile,bookArray[i].open_date, '\t');
				getline(infile,bookArray[i].item_note, '\t' );
				getline(infile,bookArray[i].item_condition, '\t');
				getline(infile,bookArray[i].product_id,'\t');
				getline(infile,bookArray[i].market, '\n');

				i++;
		 }


a sample of the file being read is:

If reading from the file as a string worked, could you read from the file as string and then convert the string to int/double before calculation?

x = atoi(line.c_str()); // for int, atof(line.c_str()) for double

infile >> bookArray[i].price, '\t'; It doesn do what you think, and it doesn't skips \t symbol. All getlines after that will be messed up. It is better to not mix up stream extraction and getlines unless you exactly know how it is works.

Carm. I'm going to try to do what you are sugesting now with this code:

1

string Text = "456"; // string containing the number

int Result;          //number which will contain the result

istringstream convert(Text); // stringstream used for the conversion constructed with the contents of 'Text' 
                             // ie: the stream will start containing the characters of 'Text'

if ( !(convert >> Result) ) //give the value to 'Result' using the characters in the stream
    Result = 0;


MiiNiPaa. I am interested in how you would code it?

Probably get it to stringstream and convert from it
