Case Study Based Question

Schools use “Student Management Information System” (SMIS) to manage student related data. This system provides
facilities for:

Photo

• Recording and maintaining personal details of students.
• Maintaining marks scored in assessments and computing results of students.
• Keeping track of student attendance, and
• Managing many other student-related data in the school.

Let us automate the same step by step.

Identify the personal details of students from your school identity card and write a program to accept these details for all students of your school and display them in this format.
