(C++) operator<

 

operator< is the operator to determine if the left-hand instance is less or equal the right-hand instance.

 

The following code uses operator< to determine that one plus two is less than four:

 

---

#include <iostream> int main() {   if (1 + 2 < 4) std::cout << "One plus two is less or equal than four\n"; }

 

operator< is encapsulated by the functor std::less.
