The std::regex_match() function from the header file, accepts a string as the first argument and a regex pattern as the second argument. It returns true if the given string matches the given regex pattern.. Now, to check if all string elements of an …

Programmers may assume that certain code sequences execute too quickly to be affected by an interfering code sequence; when they are not, this violates atomicity.
