AS_Ch11_Subroutines

What are sub-programs also commonly called?

• Modules
• Subroutines
• Algorithms
• Procedures

What is the primary purpose of a sub-program?

• To create complex calculations
• To perform a specific task and be reused
• To slow down program execution
• To generate random numbers

How are sub-programs typically called in a program?

• By their full code
• By referring to their name
• By copying their entire code
• By creating a new instance

What is a parameter in a sub-program?

• A constant value
• A variable used for input to the sub-program
• A return value
• A global variable

What distinguishes a procedure from a function?

• Procedures always return a value
• Functions return a value while procedures do not
• Procedures are faster
• Procedures use more memory

What are the two main categories of pre-existing sub-programs?

• Advanced and basic
• Complex and simple
• Built-in and library
• Permanent and temporary

What is the key characteristic of a built-in sub-program?

• It requires manual installation
• It is fundamental to the basic operation of most programs
• It can only be used in specific languages
• It changes frequently

How are library sub-programs accessed?

• They are automatically available
• They must be imported or included in the program
• They are always global
• They require special permissions

What is a local variable in a sub-program?

• A variable accessible everywhere
• A variable only accessible within that sub-program
• A global variable
• A constant variable

What is the recommended practice regarding global variables?

• Use them as much as possible
• Minimize their use
• Ignore them completely
• Only use them in large programs
