Question
Thanks for your fast reply! I used 'r+' to open the file. According to my reference book (deitel & deitel), 'r+' should allow us to read and write as well, isn't it? Anyway, I will follow your advise to write the new content to another file and then rename it to the source file. :)

Answer
May be what you said regarding "r+" is correct.
But, most of the times we use "a" for reading and writing.

Since you didn't give the error string that you got when you executed the code, I tried to guess what could be wrong.
And I noticed "r+". May be "r+" is correct and something else also could be wrong.
If you could elaborate more on the error that you got, then we can try to refine our guess:-)
