Design

• Parallel 1D arrays


  Arrays that store data of the same data type
• Records


  Can hold related data of different types
• Arrays of records


  An array that stores records
• Parallel 1D arrays


  • Names array stores player names
  • Scores array stores player scores
• Player record


  Can hold name and score data
• Array of player records

  • Can store names and scores of multiple players
• Structure diagram


  Graphically shows the steps needed to solve a problem
• Top level design


  Shows the major steps of a program solution
• Top level design for program to read names/IQs, calculate average IQ, find highest IQ


  • Read names/IQs from file
  • Calculate average IQ
  • Find/display name of person with highest IQ
• Data flow


  Shows the information that will flow in and out of sub-programs
• Data flow for program to read names/IQs, calculate average IQ, find highest IQ


  • Arrows show data flow in/out of each sub-program
• Design refinements


  Break down each main step into smaller steps
• Refinements for program to read names/IQs, calculate average IQ, find highest IQ


  • Detailed steps for each main program component
