Good old c. Not even c++ can touch it in performance or program size.

I love C Language.  I am not saying anything bad about C++, but it is a just super structure.

Code

#include <stdio.h>
#include <string.h>

/*  

    Some C language to begin chatbot design. 

*/

int main()
{
  /* DATA */
  char stimulus[72];
  int match;

  /* INPUT */
  printf("Say something: ");
  fgets(stimulus,72,stdin);

  /* PROCESS */
  if (strcasecmp(stimulus, "hello\n") == 0) printf("You greeted me.\n");

  /* OUTPUT */
  printf("You said: %s\n",stimulus);
  return(0);
}

Program Output:

Tell me something: hello
You greeted me.
You told me: hello

It is simple, but simple is a good place to start sometimes.
