T-Level DPDD: Sequential Programming Concepts Quiz

What are the three basic forms of control in programming?

• Sequence, iteration, and selection

• Sequence, iteration, and compilation

• Iteration, selection, and debugging

• Compilation, selection, and iteration

In programming terms, what does the concept of 'sequence' refer to?

• When one instruction follows another

• When a program makes a decision

• When a program repeats a set of instructions

• When a program is compiled

What is the role of a compiler in sequential programming?

• To start at the beginning and work through the program line by line

• To make decisions within the program

• To repeat certain instructions

• To debug the program

What is the process of carrying out lines of code, one at a time, in the order in which it was written called?

• Procedural or sequential programming

• Iterative programming

• Branching programming

• Debugging

What does this pseudocode do?

• Allows a user to input two numbers, add them, and print out the result

• Allows a user to input a string and print it

• Allows a user to input two numbers and multiply them

• Allows a user to input a number and find its square

What is the purpose of having a logical order in a program?

• To make the code look neat

• To ensure the program operates correctly

• To confuse the programmer

• To save memory

In this pseudocode, what will happen if the order of instructions is changed such that 'SET result TO number1 + number2' comes before 'RECEIVE number2 FROM (INTEGER) KEYBOARD'?

• The program will run correctly

• The program will crash on line 02

• The program will display an incorrect result

• The program will not compile

What error will the compiler raise if 'SET result TO number1 + number2' is executed before 'RECEIVE number2 FROM (INTEGER) KEYBOARD'?

• Syntax error

• Type error

• Runtime error: local variable 'number2' referenced before assignment

• Logical error

What is the purpose of initializing variables at the start of a program?

• To save memory

• To avoid using undeclared variables

• To make the code run faster

• To make the code look cleaner

In this pseudocode, what is the initial value of the variable 'result'?

• 1

• 5

• 0

• 10
