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;
