1. This problem is pertaining to the HTML language. You can create your own web page by placing an HTML page in the “public html” directory within your home directory of your Linux account.
(1) Write an HTML ?le that contains all needed basic component of an HTML page and test it;
(2) Change the previous HTML ?le so that it contains some syntax errors and load the changed ?le to see if there is any displayed di?erence.
(3) Write a HTML ?le that uses both tables and frames. You may also use other HTML elements if necessary. Brie?y describe the functionalities and purposes of the ?le you write.
2. Assume that the input is of the format:
name1 = value1&name2 = value2& · · · namen = valuen
Some of the valuei could be empty, i.e. it is possible to have
namei = &namei+1 = valuei+1
Write a Perl script that extracts all namei and valuei pairs, and print them out like:
name1 is value1
name2 is value2
· · ·
namen is valuen
A ?le of student grade information has the following format:
Humphries, Tired L TH25769 [email protected] student
Nadash, Maly L M NM1253 [email protected] student
Kumar, Anihara Sim AK2775 [email protected] student
Curry, Sunny SC2062 [email protected] student
The value of the ?rst column is the last name, followed by the comma sign ’,’, followed by middle and initial of the student. Please note that the ”blank” spaces between the words, numbers, email addresses and so on may be white space character, or may be a tab character. Please also note that the number of ?elds in the ?rst name and middle initial names is a variable. It can be any where from one and up.
(1) Write a Perl script that takes an input ?le of the above format, and correctly do the following:
a. Construct and print out a ”username” based on the last name/?rst name/middle initial of each student, like this:
Humphries_Tired_L
Nadash_Maly_L_M
b. Extract the email address of each student.
(2) Do the same with a PHP script.
