Chapter 1: Problem 17

What four items should you identify when defining what a program is to do?

Short Answer

Expert verified

Answer: The four crucial items to consider when defining a program's purpose and functionality are: 1. Identifying the input(s), 2. Determining the output(s), 3. Defining the desired functionality, and 4. Establishing the performance requirements.

Step by step solution

1. Identify the input(s)

The first item to consider is the input(s) of the program. These could be data or specific information, user interactions, or other external inputs needed to perform the program's tasks. Define what type of input the program expects and from where the input comes, and determine how the program processes that input.

2. Determine the output(s)

The second item is to identify the output(s) of the program. This is the end goal or result that the program aims to produce after processing the input. Define what the program will produce or display as output and determine how the output is presented or delivered (e.g., text, images, file format, etc.).

3. Define the desired functionality

The third item to consider is the functionality the program needs to provide to achieve the desired result. This includes identifying the specific tasks, operations, or calculations the program will perform to transform the input into the desired output. Determine the necessary steps, algorithms, or methods the program must use to accomplish its tasks, and ensure that these are well-defined for implementation.

4. Establish the performance requirements

The fourth item to identify is the performance requirements for the program. This encompasses factors such as runtime, memory usage, or response time, which all have a significant impact on the user experience and the program鈥檚 overall efficiency. Define the performance requirements based on what the program is intended to do, its target audience, and the resources available to ensure that it will work efficiently and effectively.
