public member function
<regex>

std::regex_token_iterator::operator!=

bool operator!=(const regex_iterator& rhs) const;
Compare regex_token_iterator for inequality
Returns true if rhs does not compare equal to the regex_token_iterator object.

Two regex_token_iterator compare equal if any of these is true:
  • They are both end-of-sequence iterators
  • One was constructed as or assigned to a copy of the other and are now pointing to the same submatch.
  • They were both constructed with equivalent arguments for first, last, submatch(es) and flags, both use the same regex object, and both now point to the same submatch.

Parameters

rhs
Another regex_token_iterator object of the same type.

Return value

true if both regex_token_iterator do not compare equal. false otherwise.

// regex_token_iterator example
#include <iostream>
#include <string>
#include <regex>

int main ()
{
  std::string s ("this subject has a submarine as a subsequence");
  std::regex e ("\\b(sub)([^ ]*)");   // matches words beginning by "sub"

  std::regex_token_iterator<std::string::iterator> rend; // end-of-sequence iterator

  // iterate over second submatches of each match:
  std::regex_token_iterator<std::string::iterator> rit ( s.begin(), s.end(), e, 2 );

  while (rit!=rend) {
    std::cout << *rit << std::endl;
    ++rit;
  }

  return 0;
}

Output:
