for_each.cpp

For_each函数的用法！

#include <functional>
#include <vector> 
#include <algorithm>
#include <iostream>

using namespace std;
//template <class T> 
class out_times_x 
{
private:
	int multiplier;

public:

	out_times_x(const int& k) : multiplier(k) { }

	void operator()(const int& x) { cout << x * multiplier << " " << endl; }

};


int main ()
{
	int sequence[5] = {1,2,3,4,5};  

	vector<int>  v(sequence, sequence+5);


	out_times_x f2(3);

	for_each(v.begin(),v.end(),f2);   // Apply function

	system("pause");


	return 0;
}
