• The system design specification consists of the following:
• Executive (or Management) Summary: Provides a brief overview of the project for company managers and executives. Outlines the development efforts to date, current status report, summary of project costs to date and remaining costs, review of the overall benefits of the new system, presents the systems development phase schedule, and highlights any issues that management will need to address.
• System Components: Contains the complete design for the new system, including user interface, outputs, inputs, files, databases, and network specifications. Also should include source documents, report and screen layouts, DFDs, O-O diagrams, and all other relevant documentation.
• System Environment: Describes the constraints, or conditions, affecting the system, including any requirements that involve operations, hardware, systems software, or security.
• Implementation Requirements: Specifies start-up processing, initial data entry or acquisition, user training requirements, and software test plans.

• Appendices: Supplemental material, such as copies of documents from the first three phases, can be included if they would provide easy reference for readers.

(Unpacking Characters from Unsigned Integers) Using the right-shift operator, the bitwise AND operator and a mask, write function unpackCharacters that takes the unsigned integer from Exercise 22.11 and unpacks it into two characters. To unpack two characters from an unsigned two- byte integer, combine the unsigned integer with the mask 65280 (11111111 00000000) and right- shift the result 8
bits. Assign the resulting value to a char variable. Then, combine the unsigned in- teger with the mask 255 (00000000 11111111). Assign the result to another char variable. The pro- gram should print the unsigned integer in bits before it’s unpacked, then print the characters in bits to confirm that they were unpacked correctly. What will be an ideal response?
