Answer 1

`Hey,

Note: Brother if you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

The goals of software engineering are straightforward and easy to understand – but they aren’t always easy to meet. This is because there are so many different ways to approach software engineering and so many outcomes that are possible.

, there are distinct and important goals of software engineering. Everyone designing, developing, testing, or maintaining software and/or application portfolios need to ensure that their software is:

Good design leads to software that is:

1. Correct – does what it should

2. Robust – tolerant of misuse, e.g. faulty data

3. Flexible – adaptable to shifting requirements

4. Reusable – cut production costs for code

5. Efficient – good use of processor and memory

Software Elegance measures the ability to deliver software value with less code complexity. A low Software Elegance score indicates decreased quality in the code resulting in higher defects that become costly to fix at mid-term.

Criteria of Elegant code:

• Correctness. IMHO no wrong code can truly be elegant.
• Succinctness. Less code means less to go wrong, less to understand*.
• Readability. The easier it is to understand code, the easier to maintain.
• Performance. To a point. Prematurely pessimized code cannot truly be elegant.

Kindly revert for any queries

Thanks.
