Computer programs are created to make computers and robots do things. Which of these are programming languages?
- A.
Roamer
- B.
Scratch
- C.
Python
- D.
Flowchart
Correct Answer(s)
A. Roamer
B. Scratch
C. PythonExplanation
Roamer, Scratch, and Python are programming languages. Programming languages are used to create computer programs and instruct computers and robots on what tasks to perform. Roamer is a programming language specifically designed for educational robots, while Scratch is a visual programming language used for creating interactive stories, games, and animations. Python is a general-purpose programming language widely used in various applications, including web development, data analysis, and artificial intelligence. Flowchart, on the other hand, is not a programming language but a graphical representation of a process or algorithm.Rate this question:

When we write a program we need to keep track of values as they change. The image shows some values that the program is changing and checking. Select the general name for the values of this type.
- A.
Sequence
- B.
Subprogram
- C.
Variable
- D.
Loop
Correct Answer
C. VariableExplanation
When writing a program, we often need to keep track of values as they change. These values can be assigned different values and checked at different points in the program. The general name for these values is "variable." Variables are used to store and manipulate data in a program. They can hold different types of values such as numbers, strings, or boolean values, and their values can be modified throughout the program's execution.Rate this question:

Which of the following prints "1" ?
- A.
IF 4>3 THEN PRINT "0" ELSE PRINT "1"
- B.
IF 7>4 AND 5
- C.
IF 7>3 OR 3>5 THEN PRINT "1" ELSE PRINT "0"
- D.
IF 7>9 OR 2>5 THEN PRINT "1" ELSE PRINT "0"
Correct Answer
C. IF 7>3 OR 3>5 THEN PRINT "1" ELSE PRINT "0"Explanation
The correct answer is "IF 7>3 OR 3>5 THEN PRINT '1' ELSE PRINT '0'". This statement will evaluate whether 7 is greater than 3 or if 3 is greater than 5. Since 7 is indeed greater than 3, the condition will be true and the program will print "1".Rate this question:

Computer programming is an important aspect of computer science.Which of these are true?
- A.
Algorithm -> specification -> product -> programming
- B.
Algorithm -> specification -> programming -> product
- C.
Specification -> algorithm -> programming -> product
- D.
Specification -> programming -> algorithm -> product
Correct Answer
C. Specification -> algorithm -> programming -> productExplanation
This answer is correct because it follows the logical order of steps in the process of computer programming. First, a specification is created to outline the desired outcome or requirements of the program. Then, an algorithm is developed to determine the step-by-step instructions for achieving the desired outcome. Next, the programming phase takes place where the algorithm is translated into a programming language and implemented. Finally, the end result is the product, which is the functioning program.Rate this question:

At the end of the Sugar Squash game a player had gained the following sweets choco=9; minto = 3; chews=5; sherbet=0The game applies this algorithm to award the score - read the program carefully.Use logic & paper & pencil to work out which of these are true
- A.
Choco < minto
- B.
(chews+minto) < ( choco - sherbet)
- C.
Sherbet > chews
- D.
Chews + sherbert = 7
Correct Answer
B. (chews+minto) < ( choco - sherbet)Explanation
In order to determine if the statement is true, we need to substitute the given values into the equation and evaluate it.
Given: choco = 9, minto = 3, chews = 5, sherbet = 0
Substituting the values into the equation, we get:
(5 + 3) < (9 - 0)
8 < 9
Since 8 is indeed less than 9, the statement is true.Rate this question:
