Function object for performing division. Effectively calls operator / on two instances of type T.
Syntax :
template struct divides : binary_function
{
T operator() (const T& x, const T& y) const {return x/y;}
};
Template Parameters :
T - Type of the arguments and return type of the functional call.
The type shall support the operation (operator /).
Member types :
x : Type of the first argument in member operator()
y : Type of the second argument in member operator()
result_type : Type returned by member operator()
Example :
#include <iostream> // std::cout
#include <functional> // std::divides
#include <algorithm> // std::transform
int main()
{
int first[] = { 10, 20, 30, 40, 50 };
int second[] = { 1, 2, 3, 4, 5 };
int results[5];
std::transform(first, first + 5, second, results, std::divides< int >());
for ( int i = 0; i < 5; i++)
std::cout << results[i] << " " ;
return 0;
}
|
Output:
10 10 10 10 10
Another Example :
#include <bits/stdc++.h>
int main()
{
int arr[] = { 10, 10 };
int size = sizeof (arr) / sizeof (arr[0]);
int num = 100;
int result;
result = std::accumulate(arr, arr + size, num, std::divides< int >());
std::cout << "The result of (100 / 10) / 10 is " << result;
return 0;
}
|
Output:
The result of (100 / 10) / 10 is 1
