How to Get User Input and Validate It Using C++ (Simple)

Greetings, today we shall be looking at how to get user input, how to print that user input to the screen and how to validate the user input using a function. This tutorial works with all other C++ validation tutorials I have posted, as they cover many ways to validate user input.

This tutorial is aimed at getting user input using a console application.

This tutorial is demonstrating how to get user input and how to validate that input using a function. Please consult my other C++ validation tutorials for more details on how we can validate data.

To get user input and validate it in C++, we firstly create a variable that will be used to store the user input. After that we use std::getline. This will allow the user to type and the function gets the contents of a line in the C++ console after the user hits enter. We pass in std::cin and the variable we created earlier into the std::getline function.

To validate the user input, we need to pass the variable into a validation function we create. We can use an if statement to check if the validation function returns a true or a false. We can then do different things, depending on if the user input was valid or not.

Thanks for watching this tutorial on how to get and validate user input.
