Study Notes
Meaning of a Program
- A computer program is a set of instructions that a computer uses to perform a specific task.
- It is usually written by a computer programmer using a programming language.
Characteristics of a Good Program
- Portability: The ability of an application to run on different platforms (operating systems) with or without minimal changes.
- Readability: A program should be written in a way that makes it easy for other programmers or users to follow the logic without much effort.
- Efficiency: A program should utilize the least amount of memory and processing time.
- Structural: A program should be broken down into subtasks that are developed independently, making it more readable, and easier to test and document.
- Flexibility: A program should allow changes without requiring a complete rewrite.
- Accuracy/Correctness: A program should do what it is meant to do according to its design specification.
- Generality: A program should be applicable to similar tasks within the same domain.
- Maintainability: A program should be easy to modify to satisfy new requirements.
- Reusability: A program should be easy to reuse in developing other programs.
- Clarity: A program should be clear enough to be understood by others.
- Security: A program should protect the information it is responsible for.
- User-friendliness: A program should be easy to use by the intended users with a sensitive user interface.
- Robustness: A program should be able to respond to unexpected conditions, such as incorrect input.
