sorry, but no homework...

I can even start, because I tried to use the samples I have in my book "CGI programming in the WWW", but they use pointers, and I don't understand that much.

I can simply give you some suggestions but no code. fread() is a function which
reads a specified number of equal-sized data items from an input stream into a block. It works on binary files.

Use fseek to set the position in the file. the position is (n-1)*sizeof(struct)
