Which of the following is NOT a type of algorithm?
- A.
Program
- B.
Flowchart
- C.
Decision Table
- D.
Pseudocode
Correct Answer
A. ProgramExplanation
A program is not a type of algorithm. An algorithm is a step-by-step procedure or set of rules for solving a problem, while a program is a set of instructions written in a specific programming language to be executed by a computer. Although a program may implement an algorithm, it is not considered a type of algorithm itself. Flowchart, decision table, and pseudocode, on the other hand, are different ways to represent algorithms.Rate this question:

A nAge variable is declared to store the age of a person. How would you intialize the variable to 25? (Choose all that apply)
- A.
25 = nAge
- B.
NAge = 25
- C.
NAge is 25
- D.
Display "Enter the age" Accept nAge
- E.
Set nAge to 25
Correct Answer(s)
B. NAge = 25
D. Display "Enter the age" Accept nAgeExplanation
The correct answers are "nAge = 25" and "Display 'Enter the age' Accept nAge".
- "nAge = 25" assigns the value 25 to the variable nAge, initializing it to 25.
- "Display 'Enter the age' Accept nAge" prompts the user to enter the age and accepts the input into the variable nAge. This also initializes nAge to 25 if the user enters 25.Rate this question:

Indicate whether the following statements are true or false. Statement 1: A variable needs to be declared before being used in a program Statement 2: A variable can be used without being initialized.
- A.
Statement 1 is false and Statement 2 is true
- B.
Both statements are false
- C.
Statement 1 is True and Statement 2 is false
- D.
Both statements are true
Correct Answer
C. Statement 1 is True and Statement 2 is falseExplanation
In programming, it is necessary to declare a variable before using it, as stated in Statement 1. This means that the variable's type and name must be specified before it can be used in the program. On the other hand, Statement 2 is false because a variable cannot be used without being initialized. Initialization refers to assigning a value to the variable before it is used. Therefore, the correct answer is that Statement 1 is true and Statement 2 is false.Rate this question:

Study the following pseudocode. begin numeric nNum1, nNum2, nNum3 nNum1 = 20 nNum2 = 4 nNum3 = nNum1 % nNum2 Display nNum end What will be the output?
- A.
0
- B.
5
- C.
Undefined
- D.
1
Correct Answer
A. 0Explanation
The output will be 0 because the % operator in programming represents the modulus operation, which calculates the remainder when one number is divided by another. In this case, nNum1 (20) is divided by nNum2 (4), and the remainder is 0. Therefore, the value of nNum3 will be 0, and it will be displayed as the output.Rate this question:

If an expression contains an addition operator, a less than operator, and a subtraction operator, which operator has a higher priority when evaluating the expression?
- A.
Addition operator
- B.
Subtraction operator
- C.
Less than operator
- D.
All the three operators
Correct Answer
D. All the three operatorsExplanation
In most programming languages, operators have precedence rules that determine the order in which they are evaluated within an expression.
In this case, the priority of operators is typically as follows:
Less than operator (<)
Addition operator (+)
Subtraction operator (-)
So, the less than operator has the highest priority, followed by the addition operator, and then the subtraction operator.Rate this question:

Correct Answer(s)
A. =
C. !=
D. <=Explanation
Relational operators are used to compare values and determine the relationship between them. These operators include "=", "!=", and "<=".
"=" is used for equality comparison, "!=", for inequality comparison, and "<=" for less than or equal to comparison.
The "%" operator is the modulus operator used for finding the remainder of a division operation and is not a relational operator. Similarly, the "*" operator is the multiplication operator and is not a relational operator.Rate this question:

What is the result of the following pseudocode? begin numeric nNum1, nNum2, nNum3, nResult nNum1 = 8 nNum2 = 9 nNum3 = 10 nResult = nNum1+nNum2*nNum3/45+15 Display nResult end
- A.
9.5
- B.
0
- C.
90
- D.
25
- E.
60
Correct Answer
D. 25Explanation
The pseudocode calculates the value of nResult by performing a series of arithmetic operations. First, it multiplies nNum2 and nNum3, resulting in 90. Then, it divides the product by 45, resulting in 2. Finally, it adds nNum1 and the previous result, resulting in 25. Therefore, the correct answer is 25.Rate this question:

NNum1 = 2, nNum2 = 3
- B.
NNum1 = 3, nNum2 = 3
- C.
NNum1 = 3, nNum2 = 2
- D.
NNum1 = 2, nNum2 = 2
Correct Answer
C. NNum1 = 3, nNum2 = 2Explanation
In the given program, nNum1 and nNum2 are initially assigned values 2 and 3, respectively. Then, nSwap is assigned the value of nNum1, which is 2. After that, the value of nNum1 is updated to the value of nNum2, which is 3. Finally, the value of nNum2 is updated to the value of nSwap, which is 2.
So, after the program executes:
nNum1 = 3
nNum2 = 2Rate this question:

- A.
The result is even
- B.
The result is odd
- C.
Even
- D.
Odd
- E.
Nothing is displayed
Correct Answer
A. The result is evenExplanation
When the program executes, it first prompts the user to enter number 1 and number 2. The values 6 and 4 are then entered respectively for number 1 and number 2. The program then calculates the sum of number 1 and number 2, which is 10. Since 10 is an even number, the condition in the if statement is true, and the program displays "The result is even". Therefore, the correct answer is "The result is even".Rate this question:
