C++遍历for_each

#include <iostream>
#include <stack>
#include <vector>
#include <algorithm>
using namespace std;
//打印数组
class bianli
{
public:void operator()(int val){cout << val << " ";}
};
void printVector(int val)
{cout << val <<" ";
}
void test01() 
{vector<int> v1;   //此时,v1的大小和容量都为0.for (int i = 0; i < 10; i++){v1.push_back(i);//向v1中插入数据.}//用for_each遍历v1  普通函数输出 后面不带括号vector<int>::iterator it = v1.begin();for_each(it,v1.end(),printVector );cout << endl;bianli shuchu0;//用for_each遍历v1 仿函数输出  后面带括号  实际上传的是一个匿名对象.for_each(it, v1.end(), bianli());cout << endl;for_each(it, v1.end(), shuchu0);
}int main() {test01();
}

输出结果:
