BSCS 3-5: PPL Final Quiz - 1-28-2025

Which of the following is an example of an explicit sequence control structure?

• Sequential execution of statements in the order they are written

• Use of parentheses in mathematical expressions to specify the order of operations

• Built-in rules of precedence in a high-level programming language

• Automatic function calls in functional programming languages

Consider the following expression: A = B + D / K. What would be the output if the language adheres strictly to implicit sequence control without parentheses? Assuming: B = 10, D = 20, K = 5

• 6

• 14

• 18

• 50

Which of the following best demonstrates a postfix (reverse Polish) notation for the expression (A + B) * C?

• * + A B C

• A B + C *

• C * A B +

• + A B C *

In a programming language like Java, which of the following scenarios involves prefix notation?

• A++;

• A = A + 1;

• A += B;

• ++A;

What will be the output of the following Java code? (see the image)

• 17

• 16

• 15

• Compilation Error

Which of the following control structures is least dependent on sequence control?

• If-Else statements

• Loops

• Switch-case structures

• Recursive function calls

What is the primary benefit of using prefix or postfix notations in certain languages like Java for increment or decrement operations?

• Allows efficient evaluation of expressions without ambiguity

• Eliminates the need for operator precedence

• Simplifies debugging

• Enhances readability of expressions

Which of the following scenarios correctly describes the concept of functional composition in sequence control?

• Assigning the output of one function to multiple variables

• Replacing a variable value using an explicit sequence

• Using nested function calls to define a computation

• Writing multiple statements sequentially within a block

For the infix notation A * (B + C), what would be the equivalent prefix notation?

• A B C + *

• * + B C A

• * A + B C

• A * + B C

Which of the following statements is true about implicit sequence control?

• It requires the programmer to manually specify the order of execution

• It is automatically determined by the rules of the programming language

• It overrides any parenthesized expressions

• It is used only in machine or assembly languages
