**1 – State your simple business problems to be solved (P1) 1.1 Overview about algorithm
- Definition:** An algorithm is a procedure used for solving a problem or performing a computation. Algorithms act as an exact list of instructions that conduct specified actions step by step in either hardware- or software-based routines. *** Example:
- Characteristics:**
- Possibility: Program can solve problem with the resources are given
- Independent: Algorithm doesn’t need to use a certain programming language to solve the problem
- finiteness: The problem must be handled by the algorithm after a predetermined number of steps. 1.2 Represent a small and simple problem The problem I will represent is about sorting student’s grade in descending order. This is a simple way for teacher to sort the list of the class.
To solve this problem, I use the bubble sort algorithm due to it is the simplest. This algorithm will swap two consecutive grade if the next grade is greater than the current until the sequence grades has been sorted in order and sort the name in order. 2 – Analyse the problem and design the solutions by the use of suitable methods (P1) 2.1 Analyse the problem
*** Input function:**
*** Search function:**
3 – Demonstrate the compilation and running of a program (P1 – M1) 3.1 Introduce how the problem is solved To solve this problem, I apply procedural programing to divide it into small tasks so that I can easily solve the problem. In the input information stage, I use if-else conditional statement and for and do-while loops to consider if the ID is duplicate or not and to see if the grade is in a range from 0 to 10. **3.2 Source code and screen shots of the final result
- Sort grade in ascending order:
- Sort name from A to Z:
- Sort name form Z to A:
- Exit the program: 3.3 Explain briefly what is Software Development Life Cycle SDLC is a process followed for a software project, within a software organization. It comprises of a thorough plan outlining how to create, maintain, replace, and modify or improve particular software. The life cycle outlines an approach for enhancing both the general software development process and the quality of the final product. There are 6 stages in Software Development Life Cycle:
- Stage 1: Planning and requirement analysis: gathering pertinent data about the issue and determining the inputs, outputs, and other elements required to address the issue
- Stage 2: Defining requirement: determining what the application is intended to achieve and its requirements is taken into account during planning
- Stage 3: Designing the product architecture: solve the problem, develop appropriate algorithms based on the requirements analysis
- Stage 4: Building or developing the product: If the design is carried out in a comprehensive and organized manner, code generation may be finished without much problem.
