(C++) std::less_equal

 

std::less_equal is an STL predicate to perform operator<= on two values.

 

#include <algorithm> #include <cassert> #include <functional> #include <vector> int main() {   //Create a std::vector with values {0,1,2,3,4,5}   std::vector<int> v;   for (int i = 0; i!=6; ++i) v.push_back(i);   //Count the values less or equal to two   const int n     = std::count_if(         v.begin(),v.end(),         std::bind2nd(std::less_equal<int>(),2));   //Assume there are three values less or equal to two   assert(n==3); }
