sorry, but no homework...<br />
<br />
I can even start, because I tried to use the samples I have in my book &quot;CGI programming in the WWW&quot;, but they use pointers, and I don't understand that much.<br />

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

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

If you have problems with pointers, i can send you tutorial about this(write you EMail).

Struct

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
