Y10 - Subprograms, Procedures, Functions

Definition of a subprogram

• A sequence of instructions to perform a specific task with an identifiable name

• Breaking down a problem into smaller more manageable chunks

• Allows values to be passed into a function

Definition of a Function

• A subprogram that executes a block of code when called. It does not return a value

• A subprogram that returns a value

• Used in a subprogram to allow values to be passed into them

Definition of a Procedure

• The values held in the brackets of a subprogram call.

• A subprogram that returns a value

• A subprogram that executes a block of code when called. It does not return a value

Definition of a Parameter

• Used when defining a subprogram to allow values to be passed into them

• A sequence of instructions to perform a specific task with an identifiable name

• The values held in the brackets of a program call.

Definition of an Argument

• A subprogram that returns a value

• Used when defining a subprogram to allow values to be passed into it

• The values held in the brackets of a subprogram call

Definition of a return value

• A value that is returned by a procedure

• A value that is returned by a function

• Used in a subprogram to allow values to be passed into them

Definition of Decomposition from Computational Thinking

• Breaking down a problem into smaller subproblems to make the more manageable

• Returning a return value from a function

• Creating step by step instructions to perform a task or solve a problem
