What is the purpose of data types in programming?

• Data types are used to determine the color of text in programming

• Data types in programming are used to define the type of data that a variable can hold.

• Data types are used to define the size of images in programming

• Data types are used to control the speed of animations in programming

Explain the difference between a function declaration and a function call.

• A function declaration and a function call are the same thing.

• A function declaration executes the function, while a function call defines the function.

• A function declaration is used for variables, while a function call is used for loops.

• A function declaration defines the function, while a function call executes the function.

How are arrays used in programming?

• Arrays are used to perform mathematical operations in programming.

• Arrays are used to store only one value in programming.

• Arrays are used to create loops in programming.

• Arrays are used to store multiple values of the same data type under a single variable name in programming.

What is the syntax for declaring an integer variable in Python?

• int variable_name = 0

• variable_name = 0

• variable_name = '0'

• variable_name == 0

Define the concept of a return type in functions.

• A return type in functions specifies the data type of the value that the function will return after its execution.

• A return type in functions specifies the color of the function

• A return type in functions specifies the number of parameters the function takes

• A return type in functions specifies the name of the function

How can you access elements in an array?

• array.at(index)

• array[index]

• array{index}

• array[element]

What is the significance of parameters in function definitions?

• Parameters in function definitions are just for decoration

• Parameters in function definitions have no impact on the function behavior

• Parameters in function definitions are optional

• Parameters in function definitions are significant because they define the inputs that the function can accept.

Give an example of a built-in data type in programming.

• float

• str

• int

• bool

How can you pass an array as a parameter to a function?

• Use a string instead of an array

• Pass each element of the array as a separate parameter

• Declare the function with the array parameter type.

• Convert the array to a string before passing

What is the purpose of the if statement in programming?

• To repeat a block of code multiple times

• To stop the execution of the program

• To execute a block of code based on a condition

• To declare variables
