Question
sir,
  please tell me how can we compare the date of two files?
  and how can we delete som cotent of a file? (file is       created using object of a class)  

Answer
You can use the file functions stat and/or fstat to get the file attributes, which includes the date and time.

Deleting from the middle of a file is difficult.  You must copy from one file to another, skipping the copying of the part to be deleted.

Expertise

I can answer questions about C++, programming algorithms, Windows programming in MFC (which is C++). I cannot answer questions about STL (templates) and I have no experience with Linux. I do enjoy reviewing code and critiquing it or finding problems in it. I will also gladly show better algorithms or methods if you want to take advantage of that.

Experience

I've developed a commercial embedded C compiler/assembler and IDE with debugger toolset, of which the IDE and debugger are written in C++. I work in the industry writing high tech embedded programs and Windows programs to communicate with the embedded devices.
