C, HTML and CGI

Question

Hi ,

I have a functionality written in C. I have to give input through the html page and the operation to be processed in C (on submit of a button) and the result has to be given to the same html page.

Please help me out by given some simple examples.

Answer 1

Here is a tutorial. You will (of course) need admin access to the web server where you wish to access your program.

Answer 2

Hi,

I have gone through the tutorial mentioned. I want to display the result in the same page instead of going to the other page. How can I do that? Do I need any interface between C and HTML?

Answer 3

I have to give input through the html page and the operation to be processed in C (on submit of a button) and the result has to be given to the same html page.

It looks like you need to make an Ajax program in C.

Simplest example of CGI programming in C:

int main ()
{
     printf ("Content-Type: text/plain\n\nHello world\n");
}

The C bit is actually quite easy, the Ajax bit is more involved.
