Leave Management System In C++ With Source Code

Leave Management System In C++ With Source Code

The Leave Management System In C++ With Source Code is developed using C++ programming language, this method is built on the idea of storing and generating all employee records and leave records.

A c++ employee leave management system goal is to assist you in organizing and maintaining the records of employees who have worked for an organization.

Additionally, the user has the ability to add, access, alter, and delete employee records as well as their leave. This project does not have a login system.

This employee leave management in c++ with source code is a basic employee database for an office or company where the user can conveniently store employee records and leave records because it is not time-consuming.

The Leave Management Framework was written in the C++ programming language and has a basic coding structure that makes it easy to understand the system’s functions.

This Leave Management System In C++ Open Source design is straightforward and clean, making it easy for users to learn, use, and navigate.

These are the following features of the system

• Can Add new Employee
• Modify Current Data
• View All Employee List
• Apply New Leave Application
• Modify Current Leave Application
