This topic is about providing a solution to the problem of dynamic content has been available since the earliest days of the Web. Rather than reading the data from a file, the server can run a program in order to generate the data.

-The mechanism by which the server and the HTML-generating program communicate is called CGI (common gateway interface).

-CGI is a program is being run behind the scenes enables the content to be dynamic.

-The earliest CGIs were written in a language called C. A sample CGI written in C is shown in the following list. It generates a Web page that contains the current time and date.

cpp code

#include <stdio.h>
#include <time.h>

int main(int argc, char **argv)  {
  time_t now;

  printf("<HTML>\n");
  printf("<BODY>\n");

  time(&now);
  printf("The time is now: %s", ctime(&now));

  printf("</BODY>\n");
  printf("</HTML>\n");

  exit(0);
}
