插入迭代器

插入迭代器，依赖algorithm头文件的replace_copy

#include<iostream>
#include<string>
#include<vector>
#include<list>
#include<algorithm>
using namespace std;
int main(){
int a[]={6,100,5,100,4,3,100,2,1};
vector<int>v(a,a+9);
list<int>l;
//replace_copy(v.begin(),v.end(),inserter(l,l.begin()),100,0);
//replace_copy(v.begin(),v.end(),back_inserter(l),100,0);
replace_copy(v.begin(),v.end(),front_inserter(l),100,0);
for(list<int>::iterator iter=l.begin();iter!=l.end();++iter){
cout<<*iter<<" ";
}
cout<<endl;
system("pause");
return 0;
}
程序结果：可以自己验证

6 0 5 0 4 3 0 21

6 0 5 0 4 3 0 21

1 2 0 3 4 0 5 0 6
