函数模板，绑定适配器

[deadoggy]

最近在看essential c++，上面有一段代码，函数模板是书上的，int main是我自己写的

#include<iostream>
#include<algorithm>
#include<functional>
#include<vector>
using namespace std;

template < typename InputIterator, typename OutputIterator,
	       typename ElemType,      typename Comp         >
		   OutputIterator
		   filter( InputIterator first, InputIterator last,
		           OutputIterator To  , const ElemType &val, Comp pred )
{
	while  ( ( first = find_if ( first, last, bind1st(val,pred) )  ) != last )
	{
		cout << *first << '\n';
		*To++ = *first++;
	}
	return To;
}

int main()
{
	const int size=8;
	int num[size]={1,2,2,3,4,5,6,7};
	vector<int> number(num,num+size);
	vector<int> number2(size);
	int num2[size];
	filter ( number.begin(), number.end(), number2.begin(), 3, less<int>());
	filter ( number.begin(), number.end(), num2,            3, greater<int>() );
	for(vector<int>::iterator itr = number2.begin(); itr!=number2.end(); itr++)
		cout << *itr << '\n';
	
	for(int *i=num2; i!=num2+size; i++)
		cout << *i << '\n';

	return 0;
}

结果调试总是不过，程序都run不起来....
求各位神牛给小弟解答解答下....
万分感谢....

将bind1st改成 bind(pred,_1,val)，现在都统一成bind了，第一个参数是函数

表示不会C++

[zhxi55]

//while ((first = find_if(first, last, bind1st(val, pred))) != last) while ((first = find_if(first, last, bind1st(pred, val))) != last)
