练习3.42 将含有整数元素的vector对象拷贝到数组上

#include<iostream>
#include<iterator>
#include<vector>
using namespace std;
int main()
{
unsigned scores[11]={21,66,77,99,74,45,62,75,59,47,64};
unsigned sc[20]={};
//用整型数组初始一个vector对象
vector<int> sub(begin(scores),end(scores));
cout<<"vector输出：";
for(vector<int>::iterator it=sub.begin();it!=sub.end();it++)
cout<<*(it)<<endl;
//vector拷贝给数组
cout<<"vector拷贝给数组：";
int i=0;
for(vector<int>::iterator it=sub.begin();it!=sub.end();it++)
sc[i++]=*(it);
for(int j=0;j<11;j++)
cout<<sc[j]<<"  ";
cout<<endl;
system("pause");
}
