容器赋值问题.

#include<iostream>
#include<string>
#include<vector>
#include<list>
using namespace std;
int main()
{
    char *sa[]={"I","love","you","!"};
    list< char* > slist(sa,sa+4);
    vector< string > svec;
    //string str;
    //将list对象的所有元素赋值给vector对象
    svec.assign(slist.begin(),slist.end());
    for(list< char* >::iterator ix=slist.begin();ix!=slist.end();++ix)
        cout<<*ix<<'\t';
    cout<<endl;
    for(vector< string >::iterator it=svec.begin();it!=svec.end();++it)
        cout<<*it<<'\t';
    cout<<endl;
    return 0;
}
