There are many errors in the segment of code above. Indicate whether the following statements are CORRECT or INCORRECT: The person responsible for the IT department at the contest has been given the task to determine the output for a program segment, represented by the flowchart below. The trace table below has been compiled to determine what the output of this program segment will be if the text Y&$6@ has been entered as input. Copy and complete the trace table in your ANSWER BOOK.

Worked Solution & Example Answer:The application form below was used by a talent search organisation for candidates to enter a song writing competition - NSC Information Technology - Question 5 - 2023 - Paper 2

Step 1

Motivate the use of selection components rather than entry fields for obtaining information from users.

Answer

Using selection components, such as radio buttons or dropdown menus, improves accuracy as it limits user input to predefined choices. This not only ensures validation but also enhances the user experience by making it easier and faster for users to make selections.

Step 2

State the benefit of saving the applicants' details in a text file.

Answer

Saving the applicants' details in a text file allows for permanent storage of information, making it easier to retrieve and manage data over time compared to transient methods of data entry.

Step 3

Why would a bit button be more suitable to be used instead of a standard button?

Answer

A bit button can be linked to a prewritten or provided event or code, which can visually indicate the purpose of the button. This can enhance user interaction and clarity.

Step 4

Give the line number in the code where EACH of the following errors occur and explain the reason for the error:

Answer

5.2.1 Line 9 - A syntax error occurs because the square root of the number value must be assigned to a real variable; it is not correctly defined in the current state. 5.2.2 Line 13 - A logical error occurs because the formula should be either 'iSquare := iNumber * iNumber' or 'iSquare := SQR(iNumber)'. The computation logic is incorrectly applied. 5.2.3 Line 15 - A runtime error occurs because division by zero is undefined, resulting in a program crash if 'iNumber' is zero.

Step 5

Indicate whether the following statements are CORRECT or INCORRECT:

Answer

5.3.1 The statement is CORRECT. 5.3.2 The statement is INCORRECT.

Step 6

Give the default access modifier status of an attribute of a class.

121 rated

Answer

The default access modifier status of an attribute in a class is private, meaning it cannot be accessed directly from outside the class.

Step 7

Why will a method such as a toString() method be declared as public?

96%

114 rated

Answer

A toString() method is declared as public to make it accessible from other classes outside the object class, allowing for the conversion of an object's state to a format easily understandable to users or other system components.

Step 8

Copy and complete the trace table below:

Answer

The trace table will have the following completed entries based on the flowchart logic: Text: Y& $6@ Count: 0 Index: 1 Text (Index): one of Y&$ 6@? True Index <= Length? True Count >=3 AND Length >= 8? False Display: VALID

This process continues incrementing the index and count appropriately until the final conditions are met.
