Could anyone help me to solve this problem ?<br />
<br />
I would like to use pure C to write a very simple cgi script.<br />
<br />
OK. This script will get an input( integer ) from the user<br />
on the net, after user entered an integer and pressed the submit button. That number will store in a text file called num.txt. So, the text file should not be overwrote, it should be able to store as many as it can.<br />
<br />
Please tell me how to call that script from the html and do I have to change any thing in server conf file ?

perl in c

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.
