Which of the following might be output as a result of using a CASE tool? A. programming code B. flowcharts and data flow diagrams C. prototypes and cost / benefit analysis D. All of the above E. None of the above

The correct answer is: D. All of the above

A CASE tool is a software application that helps software developers to design, develop, and maintain software applications. CASE tools can be used to generate a variety of outputs, including programming code, flowcharts and data flow diagrams, prototypes, and cost/benefit analysis.

• Programming code: CASE tools can be used to generate programming code in a variety of programming languages, such as Java, C++, and Python.
• Flowcharts and data flow diagrams: CASE tools can be used to create flowcharts and data flow diagrams, which are graphical representations of the logic and flow of data in a software application.
• Prototypes: CASE tools can be used to create prototypes of software applications, which are working models that can be used to test the functionality and usability of the application.
• Cost/benefit analysis: CASE tools can be used to perform cost/benefit analysis, which is a process of comparing the costs and benefits of a software project.

CASE tools can be a valuable asset for software developers, as they can help to improve the efficiency and effectiveness of the software development process.
