School Management System (Student Record)
Project (Explanation):
We make this project with help of singly linkl ist. In singly link list we move forward ,so we insert data in different nodes with the help of ptr in forward movement.
1: Insert Record:
You can insert unlimited student data with the help of link-list.
2: Delete Record:
You can delete any student data with the help of his roll number.
3: Modify Record:
You can modify any student data with the help of his roll number.
4: Search Record:
You can search any student data with the help of his roll number.
5: Display Record:
You can display all students data.
6: Sum of Student(sum of nodes):
You can count number of students or number of nodes present in link list.
some output of project:
