reading specific line in a text file
<p>I have a text file that I am reading from it and writing to it using c++.
the file is like a table that has 4 fields: id,title,year,price. something like this:</p>

<p>1;c++ how to program;1990;50$</p>

<p>2;java how to program;1996;70$</p>

<p>the id is entered at the console, and then I have to search for this id in the text file and displays all the record of this id. further more, the user should be able to update a specific line in the text file. can any one help me please ? Thanks</p>
