5.1 Procedures and functions are used to enhance modularity in programs - NSC Information Technology - Question 5 - 2017 - Paper 2

A private function is only accessible within the class or unit where it is defined, whereas a public function can be accessed from outside the class or project that defines it.

The expression evaluates to True because both y and z have the value 4. Thus, bAnswer will be set to True.

In this case, since x is false, NOT (x) evaluates to True. However, since y equals 4, (y <> 4) evaluates to False. Therefore, bAnswer will be set to False.

To check if a word is a palindrome, you can follow these steps:

reverseWord <- empty string
for loop from length of word down to 1 do
    reverseWord <- reverseWord + word[loop]
if word = reverseWord then
    Output 'Word is a palindrome'
else
    Output 'Word is NOT a palindrome'

To sum the values in the left diagonal area, the algorithm could be structured as follows:

	iSum := 0;
	iRows := 5;
	for r := 1 to iRows do
		iSum := iSum + arrLightBulbs[r, r];

(a) Syntax Error: Incorrect array index format. (b) Logical Error: The statement is missing a closing bracket for the assignment. (c) Syntax Error: Index out of bounds for the defined array.

The Reset statement opens an existing text file for reading and moves the file pointer to the first record, allowing you to read from it.

The Rewrite statement creates a new text file and clears the contents of an existing file if it already exists, allowing you to write new data.

The error in this statement is that objSchool.create('MySchool',500); incorrectly implies instantiation instead of calling a constructor directly. An object cannot create or instantiate itself; it needs to be initialized with the new keyword.

This statement is incorrect due to an improper order of arguments, as the first argument should match the class type for instantiation.

Here, there is a data type mismatch error; the second parameter must be an integer, whereas a string is provided.

This task should use a Mutator method which changes the value of the NumberLearners attribute in the TSchool class.

This task requires an Accessor method to retrieve the values necessary for calculating the ratio from the TSchool class.
