filling a struct from a text file in C++
<p>guys, I have a text "sales.txt" file which contains (id, lastname, quarter, sales) in the following format.</p>

<pre><code>123 smith 1 333.20
221 doe 1 345.50
342 johnson 1 774.50
123 smith 2 333.20
221 doe 2 555.50
342 johnson 2 25.50
123 smith 3 254.20
221 doe 3 652.50
342 johnson 3 32.50
123 smith 4 354.20
221 doe 4 51.50
342 johnson 4 1000.50

<p>I'm trying to put the file into a struct for output to another text file, but so far I'm having problem with extracting the "id" and lastname. here's a portion of the code. The second method is to extract the sale by quarter and put it into array, but is not working, if someone could give me a hand with both methods</p>

<p>thanks</p>
