Question

consider the following actions which might be performed by a developer when creating a new piece of software to solve a problem: 1. thoroughly testing code with a variety of inputs 2. designing an algorithm to tackle the core problem the program hopes to solve 3. considering what outputs a program solving the problem might produce and what inputs it may require to do this 4. writing code in a high-level programming language to implement an algorithm in which order in the development cycle would these actions first appear? options: 3,4,1,2; 2,4,1,3; 2,3,4,1; 3,2,4,1

Explanation:

To determine the correct order, we analyze the software development process:

1. First, we need to understand what the program needs to do in terms of inputs and outputs (action 3). This is the problem - definition phase where we figure out the requirements.
2. Then, we design an algorithm to solve the identified problem (action 2). An algorithm is a step - by - step plan to solve the problem, and we can only design it after we know what the problem is (from step 1).
3. Next, we write the code in a programming language to implement the algorithm (action 4). We need an algorithm (from step 2) to know what to code.
4. Finally, we test the code with various inputs (action 1) to make sure it works as intended.

So the order is 3, 2, 4, 1.

Answer:

1. 2, 4, 1 (the option "3, 2, 4, 1")
