Solve the following arithmetic expression expression: 5 + 6 * 2 / 2 - 5; What is the final result?
-
5
-
6
-
11
-
None of the above
Correct Answer
A. 5Explanation
The given arithmetic expression is solved using the order of operations, which states that multiplication and division should be performed before addition and subtraction. Therefore, first, we multiply 6 by 2, resulting in 12. Then, we divide 12 by 2, giving us 6. Finally, we add 5 to 6 and subtract 5 from the sum. This results in a final answer of 6. However, the given options do not include 6 as a choice. Therefore, the correct answer is none of the above.Rate this question:

Solve the following expression: (4 * 5 + 2) > (5 * 2 / 2 ) && ! F; What is the final result?
-
True
-
False
-
Null
Correct Answer
A. TrueExplanation
The expression evaluates to True because the left side of the && operator is true. In the left side, (4 * 5 + 2) equals 22 and (5 * 2 / 2) equals 5. Since 22 is greater than 5, the left side of the && operator is true. The right side of the && operator is ! F, which means not false. Since F is not defined, it is considered false. Therefore, the right side of the && operator is true. Since both sides of the && operator are true, the final result is True.Rate this question:

It must begin with a letter
-
You can use reserve words
-
It can hold values
Correct Answer(s)
A. It can contain letters, numbers and underscore
A. It must begin with a letter
A. It can hold valuesExplanation
Variables in programming can contain letters, numbers, and underscores. This allows for flexibility in naming variables. Additionally, variables must begin with a letter, which is a standard convention in most programming languages. They are also used to hold values, allowing for the storage and manipulation of data within a program. However, using reserved words as variable names is not allowed, as these words have predefined meanings in the programming language and would cause conflicts or errors.Rate this question:

What is the result of the following? !T && !F II T = _______
-
True
-
False
Correct Answer
A. TrueExplanation
The given expression is "!T && !F || T". The "!" operator represents the logical NOT, which negates the value of the operand. "!T" evaluates to False, "!F" evaluates to True, and "T" evaluates to True. The "&&" operator represents the logical AND, which returns True only if both operands are True. Since "!T" is False and "!F" is True, the expression "!T && !F" evaluates to False. The "||" operator represents the logical OR, which returns True if at least one of the operands is True. Since "False || T" is True, the overall expression evaluates to True.Rate this question:

The expression (9 / 3 == 9 % 3) && !T || F is equal to False.
-
True
-
False
Correct Answer
A. TrueExplanation
The expression (9 / 3 == 9 % 3) evaluates to true because 9 divided by 3 is equal to 3 and 9 modulo 3 is equal to 0. The expression !T evaluates to false because the value of T is not given. The expression F evaluates to false. The && operator has higher precedence than the || operator, so the expression is evaluated as (true && false) || false. Since the first part of the expression is false, the whole expression evaluates to false. Therefore, the given answer is incorrect.Rate this question:

In solving two or more expression in a line, start solving from right to left.
-
True
-
False
Correct Answer
A. FalseExplanation
When solving two or more expressions in a line, the correct approach is to start solving from left to right, not from right to left. This is because mathematical operations follow a specific order of operations, known as PEMDAS (parentheses, exponents, multiplication and division from left to right, and addition and subtraction from left to right). Therefore, starting from the left ensures that the operations are performed in the correct order.Rate this question:
