C++ Functional Library - greater
Description
It is a function object class for greater-than inequality comparison and binary function object class whose call returns whether the its first argument compares greater than the second (as returned by operator >).
Declaration
Following is the declaration for std::greater.
template <class T> struct greater;
C++11
template <class T> struct greater;
Parameters
T − It is a type of the arguments and return type of the functional call.
Return Value
none
Exceptions
noexcep − It doesn't throw any exceptions.
Example
In below example explains about std::greater.
#include <iostream> #include <functional> #include <algorithm> int main () { int numbers[]={200,40,50,100,30}; std::sort (numbers, numbers+5, std::greater<int>()); for (int i=0; i<5; i++) std::cout << numbers[i] << ' '; std::cout << '\n'; return 0; }
Let us compile and run the above program, this will produce the following result −
200 100 50 40 30
