What is the correct term for a named storage location in memory that holds a value which can be changed during program execution?

• Constant

• Variable

• Function

• Parameter

Which of the following is the correct data type to store the value `3.14` in most programming languages?

• Integer

• Boolean

• Float

• String

What does the term "syntax" refer to in the context of programming?

• The logical flow of a program

• The set of rules that define the structure and format of valid statements in a programming language

• The process of finding and fixing errors in a program

• The output produced by a program when it is executed

Which of the following correctly describes a `for` loop?

• A loop that continues executing as long as a condition remains false

• A loop that executes a block of code a specified number of times or over a sequence

• A loop that only executes if a Boolean value is set to True

• A loop that always executes at least once before checking its condition

What is the purpose of an `if-else` statement in programming?

• To repeat a block of code multiple times

• To define a reusable block of code

• To execute one block of code if a condition is true and another block if it is false

• To store multiple values in a single variable

Which of the following best describes the concept of a function in programming?

• A variable that stores multiple values

• A named, reusable block of code designed to perform a specific task

• A type of loop used to iterate over a list

• A conditional statement used to make decisions

What will be the value of `result` after the following pseudocode is executed? ``` result = 0 for i = 1 to 4: result = result + i ```

• 4

• 8

• 10

• 16

A student declares the following array: ``` marks = [55, 72, 88, 61, 90] ``` What value is stored at index 2?

• 72

• 55

• 61

• 88

What is the difference between a local variable and a global variable in programming?

• A local variable can store more data than a global variable

• A local variable is declared inside a function and is only accessible within that function, whereas a global variable is declared outside all functions and is accessible throughout the entire program

• A global variable is faster to access than a local variable because it is stored in a different type of memory

• There is no difference; both local and global variables behave identically in all programming languages

Examine the following pseudocode and determine what is printed: ``` function calculate(a, b): if a > b: return a - b else: return b - a print(calculate(3, 9)) ```

• 12
