How to Validate an Email Address Using C++ (Simple)

Greetings, it is Max ODidily here with another C++ validation tutorial and today we shall be validating an email address the user may input in your application. We will be using regexes to make life easy.

For this C++ email validation tutorial, we can create a regex object and assign our regex to it. We then call the regex_match function with out email we wish to validate and the regex pattern to check if it matches the rules defined by our email regex.

We also perform all of this email regex validation in its own C++ function. This function will return a true if the email address is valid and false if the email address is invalid.

Email regex pattern used in this C++ tutorial: R"(^[\w-\.]+@([\w-]+\.)+[\w-]{2,4}$)"
