Example of an examination paper

Question 1 4 marks

Code, then use a simple function that contains one required and one default parameter.

Question 2 10 marks

2.1 Consider the following function:

<?php
function subtract($first_number, $second_number){
$result = $first_number - $second_number;
return $result;
}
?>

Define appropriate variables, and then use them with the function so that the following
sentence is printed:

The result of the calculation is -76. (6)

2.2 Consider the following function that works with a variable-length parameter list:

<?php
function dynamic_args() {
for($i = 0 ; $i < func_num_args(); $i++) {
echo "Argument $i = ".func_get_arg($i)."<br />";
}
}
?>

i. Use the function to produce the following lines:
Argument 0 = a
Argument 1 = b (2)

ii. Use the function again, but this time the following lines must be produced:
Argument 0 = a
Argument 1 = b
Argument 2 = c
Argument 3 = d
Argument 4 = e (2)

Question 3 28 marks

3.2 Adapt (not extend) the class above so that it makes use of a constructor method, and
two get and set methods. Use the adapted class. The output produced must be as
follows:

Hello Felicia Ngobeni! (8)

3.3 Adapt the class from (b) by making the variables private. Extend the class with a
subclass named member. Add a function that will greet the member:

Hello member f3lng0Beni! (8)

3.4 Repeat 3.3 here above but extend the Users class with a class Administrator. When
used, the member will be greeted as follows:

Hello administrator Nthabiseng007! (8)

Question 5 9 marks

Consider the following SQL code that will create a table in a database:

CREATE TABLE IF NOT EXISTS `course` (
`course_id` int(11) NOT NULL,
`course_name` text NOT NULL,
`course_descr` text NOT NULL,
`course_cost` text NOT NULL,
`course_duration` text NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
ALTER TABLE `course` ADD PRIMARY KEY (`course_id`);
ALTER TABLE `course` MODIFY `course_id` int(11) NOT NULL
AUTO_INCREMENT;

Using question mark parameters, write a prepared statement that will select the course names,
their descriptions and cost where the course_id is 12.

Question 6 8 marks

Consider the following form:




Write code that will process the form and send all the information processed in an email to
