Login to the System using C++

By Shivaani Mathan Kandasamy

In this C++ program, you can log in to the system by using Username and Password. If login credentials match then the user is logged in else error message prompts.

This is a simple C++ program for beginners who wants to learn about if....else statements.


The user should enter the login credentials firstly. If the login credentials match the system then the user is logged in. If wrong credentials are given then the error message prompts.


Both Username and Password should be entered correctly for a successful login. If anyone is also wrong then an error message prompts.

Program Summary

  1. Enter Username and Password.
  2. If valid credentials are entered then the user can log in.
  3. Else error message prompts.
