Program: Inheritance in Class - to find topper out of 10 students
Download as DOCX, PDF0 likes3,626 views
The document presents a C++ program that defines a class 'student' to store details of students, including their name, roll number, and percentage. A derived class 'topper' captures the records of the top three students based on percentages. The program collects student data, identifies the top three scorers, and displays their information.
