Overview of the templ_database () Function

The function takes as its arguments the sentence and an integer value representing the identity of the question.

The first part of the function is to translate the integer values associated with the question�s identity, into words. The question�s identities used by the template can then be matched to these. This means that a response generated for a �what� question can be matched to a template from the �what � responses in the template. This is achieved by systematically working through the template, taking each line into a buffer and comparing the contents to the identity of the sentence. Once a match is found, an appropriate template is randomly selected. The templates contain a �[� symbol. This denotes the point of insertion for the response. The insertion is executed by using temp_man(templates[rand() % no_r],sentence)

Overview of the temp_man () Function

The temp_man(templates[rand()% no_r],sentence) takes as its arguments, the randomly selected template and the sentence (the response). The function creates three arrays, splits the template at the �[� symbol and places the first half in an array called part 1. The second half is placed in an array called part 2. The array output then has part one placed in it. Next a space is placed in the array. The response is then placed into output and another space added. Finally, part 2 is added to output with a null character appended to it. The output is then passed to display.

Overview of the display ()function

The display () function takes as its arguments the output and sends the format of the web page as HTML code the output is sent within this code. The first line that is passed to the web browser is the CGI directive. In our case, the content of the web page is HTML page, i.e. "Content-Type: text/HTML".
