沒有問題.
#include<cstdio>
#include<functional>
#include<algorithm>
using namespace std;
using namespace std::placeholders;
int main(int argc, char** argv) {
int a[] = {1, 2, 3, 4, 5, 6, 7, 8, 9};
auto mul = bind(multiplies<int>(), _1, _2);
function<int(int,int)> print = bind(printf, "%d * %d = %d\n", _1, _2, mul);
auto b = bind(bind1st<function<int(int,int)>,int>, print, _1);
auto b2 = bind(for_each<int*, function<int(int)>>, a, a+9, bind(b, _1));
for_each(a, a+9, b2);
}

我用gcc version 4.5.0 20100128 (experimental) 沒問題
VS2008把auto換成function<一大串>應該也可以

沒有. auto是c++0x(c++1x?), function和bind是c++ tr1的東西

不一定要template, 反正就是代換成typeof(等號右邊)
這是懶人的好幫手啊XDD
