1.accumulate

#include <iostream>
using namespace std;// 常用算术生成算法 
#include<vector>
#include<numeric> //accumulate 的调用头文件void test01()
{vector<int>v;for (int i = 0; i <= 100; i++){v.push_back(i);}int total = accumulate(v.begin(), v.end(), 10000); //10000 是初始值cout << "Total = " << total << endl;
}int main()
{test01();cout << "------------------------" << endl;//test02();//cout << "------------------------" << endl << endl;//test03();//**************************************system("pause");return 0;
} 

2.fill

#include <iostream>
using namespace std;// 常用算术生成算法 fill
#include<vector>
#include<numeric>  //fill 的头文件
#include<algorithm> //for_each 的头文件void myPrint(int val)
{cout << val << " ";
}void test01()
{vector<int>v;v.resize(10);cout << "填充前：" << endl;for_each(v.begin(), v.end(), myPrint);cout << endl;fill(v.begin(), v.end(), 100);cout << "填充后：" << endl;for_each(v.begin(), v.end(), myPrint);cout << endl;
}int main()
{test01();cout << "------------------------" << endl;//test02();//cout << "------------------------" << endl << endl;//test03();//**************************************system("pause");return 0;
}
