Software Development Process

还好这节不是很多哈哈哈

​Software Development Process

1. Analysis

• Figure out what needs to be done (requirement/specifications)

• Break the problem into smaller problem into smaller problems to be solved

• What is known/given?

• What is known/given?

• What can/must be assumed?

• What is being asked for?

• Express requirements as tests

2. Design

• Decide how to solve the problem

• Overall structure of system

• How do the parts interact?

• What is the flow?

• What libraries/tools/frameworks can help solve the problem?

• Focus on problem solveing, not on coding details.

• Should be readable by anyone, even if they are not familiar with C++ (or any programming language).

• Algorithm

  • A detailed sequence of actions to perform to accomplish some task.

• Tools

  • Pseudocade

    • Simple English

    • Semi-formal, precise

  • Flowchart

    • Graphical

    • Formal

3. Implement

• Know what to do and have plan for how to do it

• Write tests (using test cases from Analysis phase)

• Write code to pass the tests

• Write and test small sections

4. Test

• Test

  • Run tests

• Debug

  • Fix code that fail tests

5. Repeat

• Most important thing to remember

• Repeat!!!

  • Go back to any step at any time
