A program needs to read user input, calculate a total, update a file, and print a report. Which design best follows the material's guidance for focused functions?

  1. A

    Put every operation in one function so the program has fewer function calls

  2. B

    Use global variables so all functions can share the same state

  3. C

    Make each function depend on hidden state maintained by other functions

  4. D

    Separate input, calculation, state changes, and reporting into focused functions
