Thank you so much for the valuable feedback

For the next post on this topic I would like to see a way to read those data previously existing in the file, for example a user search engine.

We can create such a database using C++ where we can save all the user data. Absolutely, I will work on your suggestions. In the next post, I will definitely bring this feature that how the data we have from another file can be searched.

Do you know if there is a way to integrate a database like My SQL into this language?

Of course, we can integrate C++ with MySQL. The way to integrate it would be that we have to use the MySQL Connector C++ library. Through this library, we can perform our database operations. It allows us to insert update or delete records directly in the database in MySQL. You can download MySQL Connector C++ from the official MySQL website. Procedure:

For this, we have to install MySQL and MySQL Connector C++.
We have to include MySQL header files appropriately in our C++ code.
Using this mysql::connection object we have to connect to the MYSQL database.
Then using C++ run different queries like SELECT, UPDATE etc.
