Project on Student Registration
Project on Student Registration
Project Introduction and scope
It is a simple c++ project for beginners to cover some basic topics. Which can help c++ beginners to build large projects and gives idea about how to make project in c++ programming.
It includes the concept of following topics
struct
Filing
Loops
Arrays
If else
Switch statement
String class functions
Project has for major functions in menu
Add Record
Update Record
Get any Record
Get all Record
Add Module
Get any module details
Get all module details
Update Module
Find Std Marks
Exit
