概要

非等値比較を行う

戻り値

!(lhs == rhs)

#include <cassert>
#include <chrono>

using namespace std::chrono;

int main()
{
  time_point<system_clock> p1(seconds(2));
  time_point<system_clock> p2(seconds(3));

  const bool result = p1 != p2;
  assert(result);
}
  • p1 != p2[color ff0000]
  • system_clock[link /reference/chrono/system_clock.md]
