Thanks for your contribution. I made some comments. Also, could you make the same change to the README.md file? |

For code sample make sure you enclose them in code blocks (using backticks).
Also for brevity, I don't include headers and a detailed implementation using main since it distracts from the example. Something like this:
// Define a simple regex pattern for an email address.
std::regex email_pattern("[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}");
// Input string to check.
std::string email = "example@example.com";
// Check if the input string matches the pattern:
if (std::regex_match(email, email_pattern)) {
// matches
} else {
// no matches
}|
|
||
| The std::regex class is initialized with a regular expression and handles parsing the regular expression. | ||
| std::regex_search() looks for a regex inside a given string, and std::regex_replace() replaces any instances of the regex inside the given string. | ||
| std::regex_iterator and std::regex_token_iterator allow iteration through matches and submatches (respectively) within the string. |

Put any class or function names in single backticks please.
