CS304 Assignment 2 Solution 2024

Question

Let suppose there is a well-known government organization with a rich history in education and public services. This prestigious institution has always strived for excellence in every aspect of its operations, and now they are committed to modernizing and streamlining their student records management system. They want to keep track of their student record for obtaining such objective they hired you as an employee. You’ve been assigned the crucial task of creating specialized software for the institution responsible for overseeing and maintaining student records. This institution plays a pivotal role in ensuring the education and administrative needs of students are met with efficiency and precision. The program must be capable of storing and processing essential student information such as the student’s name, course enrollment, and unique student ID. It should also be able to calculate and display the sum of the student’s last three digits. Your goal is to develop a program that meets all of these requirements. In order to achieve these objectives, the following table should be used as a reference guide for understanding the key elements and concepts in the code they are asked to implement. It serves as an educational example to help students grasp these concepts, and it will prepare them for real-world software development. Additionally, this code simulates a simplified “Student Record Management System,” showing how these concepts can be applied to practical scenarios. The table is given as under.
