The Creighton University home page includes a search engine for finding a student or faculty member's phone number and email address. This is an example of a Web-based client/server application. Using a Web-browser (the client), you can access a remote database of student/faculty information through a CGI program that works in conjunction with the Web server.
This assignment is the first step in developing a similar, albeit simplified, search engine. You must design and write a C++ program that reads the name (or partial name) of a person and searches for that name in a file of email addresses. Your program should then display the names and email addresses of all people whose names match. Since this program will eventually be connected to a Web server and accessed via a Web page, there are very specific requirements on the form of the input and output of your program.
The first input string specifies that all names containing the letter sequence "Dave" should be reported. Note that the letter sequence may appear anywhere in a name and case is not relevant. Thus, a search for "Dave" might find "Dave Reed", "Davender Malik", and even "Chris Muldavey" (if such a person existed). The second input string requires a match for "Dave R", thus ruling out "Davender Malik" and "Chris Muldavey".
Jim Carlson email@example.com Davender Malik firstname.lastname@example.org Premchand Nair email@example.com Dave Reed firstname.lastname@example.org Mark Wierman email@example.com
There should then be a blank line, followed by one line of output for each matching name (with <BR> at the end). For example, given the email.txt file above, the input string "lookfor=Dave+R" should yield the following output:
Content-Type: text/html Dave Reed: firstname.lastname@example.org
Similarly, the input string "find=RE" should yield the following output:
Content-Type: text/html Premchand Nair: email@example.com
Dave Reed: firstname.lastname@example.org
If no name matches the input string, then a message to that effect should be displayed. For example, the input string "name=foo" should yield the following output:
Content-Type: text/html No match found
Since this program involves parsing a string of text, ignoring case, and searching a data file, I strongly recommend that you consider using the <string>, <cctype> and <fstream> libraries that are standard in C++. You may refer to a C++ text or online resources for a review of the classes and functions defined in these libraries. For quick tips on these and other useful libraries, see my handout.
