Revise: Using SubprogramsA subprogram is a named sequence of instructions that performs a particular task. Instead of placing every instruction in one long main program, a programmer can separate tasks such as calculating a total, displaying a menu and processing scores into subprograms.
A named section of code that performs a particular task and can be called when needed, such as a function or procedure.
When explaining why subprograms help, link your answer to reuse, reduced duplication, readability or easier testing.
Apply improvements to the code given: identify a suitable subprogram, suggest a specific descriptive name, or show which lines should be indented.
