使用 for_each 调用带有成员数据的成员函数
亲爱的大家，我想为（比方说）属于同一类的成员的向量的每个对象调用一个成员函数（需要引用），如以下代码所示：
#include <functional>
#include <algorithm>
#include <vector>
#include <iostream>
using namespace std;
struct Stuff {
double x;
};
class Test {
public:
void f1(Stuff & thing);
void f2(void);
vector<Stuff> things;
};
void Test::f1(Stuff & thing) {
; // do nothing
}
void Test::f2(void) {
for_each(things.begin(), things.end(), f1);
}
int main(void)
{
return 0;
}
此代码给了我一个相关的编译器错误到未解析的重载函数类型。我也尝试过使用绑定，但似乎 f1 中所需的引用是一个问题。我知道我在这里错过了一些重要的东西，所以我借此机会解决我的问题并学习。目前，我无法安装boost，但我也想知道boost是否有助于解决这个问题。提前致谢。
Dear all, I would like to call a member function (that expects a reference) for each object of (let's say) a vector that is a member of the same class, as the following code shows:
#include <functional>
#include <algorithm>
#include <vector>
#include <iostream>
using namespace std;
struct Stuff {
double x;
};
class Test {
public:
void f1(Stuff & thing);
void f2(void);
vector<Stuff> things;
};
void Test::f1(Stuff & thing) {
; // do nothing
}
void Test::f2(void) {
for_each(things.begin(), things.end(), f1);
}
int main(void)
{
return 0;
}
This codes gives me a compiler error related to unresolved overloaded function type . I have tried also with bind, but it seems that the references requisite in f1 is one problem. I know I am missing something important here, so I take this opportunity to solve my problem and to learn. At the moment, I can't install boost, but I would like to know also if boost is useful to solve this problem. Thanks in advance.

f1标识，而应称为&Test::f1（如：成员函数f1Test的 code>）f1不接受单个参数：与任何非静态成员函数一样，它有一个隐式this参数typeTest * constBoost.Bind 确实是一个不错的选择：
f1but should be referred to as&Test::f1(as in : member functionf1of classTest)f1does not take a single argument : as any non-static member function it has an implicitthisparameter of typeTest * constBoost.Bind would indeed be a great option :
