Programming Constructs, Procedures and Functions

What is a parameter?

• A constant in a program
• A variable applied to a procedure or function
• A mathematical expression
• A data type

When a parameter is passed by value what happens?

• The variable can be changed by the procedure
• The value of the variable remains unchanged
• The variable is deleted
• The variable is copied multiple times

What is an argument?

• A parameter definition
• A mathematical operator
• A value passed to a procedure or function from the main program
• A constant

What is the purpose of a procedure?

• To always return a value
• To execute a group of repeated statements
• To perform complex mathematical calculations
• To define a new data type

In pseudocode how do you indicate the end of a procedure?

• Close procedure
• End procedure
• Stop procedure
• Terminate procedure

How are parameters passed in Python?

• By reference
• By value
• By pointer
• By memory address

What distinguishes a function from a procedure?

• Functions always return a value
• Procedures are more complex
• Functions are only used in math
• Functions cannot have parameters

In the header statement of a function what must be specified?

• Loop conditions
• Return value
• Variable names
• Constant values

What happens if arguments are passed in a different order than specified in the header?

• The program will automatically rearrange them
• The program will crash
• The program will ignore the order
• The arguments will not be processed

What is a header statement?

• A comment at the start of code
• The first statement of a procedure containing its name and parameters
• A type of variable declaration
• A mathematical formula
