This C++ Login System code is a simple console application written in C++ with no graphics. The user is prompted to enter a user name and password (which I have already pre-defined in the code). The if-else-if statements then check the user’s input.
If the login condition is true, the user will receive a welcome message. Otherwise, it will inform the user that their entry is invalid and give them four additional chances to attempt. There are five in all.
The Project’s Planning
It’s a good idea to plan ahead of time before beginning any program. Although our software is simple, it nonetheless necessitates the use of various components. The login Attempt loop counter is also increased by one. These if-else-if statements are all nested in a while loop that examines the login Attempt condition.
The program checks if login Attempt == 5 when the loop ends. The software will finish if the user tries to log in too many times. If the login was successful, the loop will break and print a thank you message.
The first step is to determine which C++ libraries are required for our program to run. These will be at the beginning of the presentation.
Import a library’s header files with #include. Iostream is the first library that our software requires. We’ll use this library to manage our C++ Login Program basic input and output.
What is a C++ library?
A C++ library contains code that can be used in a variety of projects. A library usually contains methods and classes that deal with a generic procedure that many developers are likely to use. C++, for example, includes libraries for processing input and output, which is a common task in many programs.
