事实上，只要有了 `<` 运算符，则其他五个比较运算符的重载也可以很容易实现。



```cpp

bool operator< (const T& lhs, const T& rhs){ /* 这里重载小于运算符 */ }

bool operator<(const T& lhs, const T& rhs) { /* 这里重载小于运算符 */

}

bool operator>(const T& lhs, const T& rhs) { return rhs < lhs; }

bool operator<=(const T& lhs, const T& rhs) { return !(lhs > rhs); }

bool operator>=(const T& lhs, const T& rhs) { return !(lhs < rhs); }

bool operator==(const T& lhs, const T& rhs){ return !(lhs < rhs)&&!(lhs > rhs); }

bool operator==(const T& lhs, const T& rhs) {

  return !(lhs < rhs) && !(lhs > rhs);

}

bool operator!=(const T& lhs, const T& rhs) { return !(lhs == rhs); }
