const_iterator和const iterator的区别

#include <iostream>
#include <string>
#include<fstream>
#include <algorithm>
#include <iterator>
#include <vector>
using namespace std;
 
int _tmain(int argc, _TCHAR* argv[])
{  
    vector<int> myVec;
    myVec.push_back(0);
    myVec.push_back(1);
    myVec.push_back(2);
 
    copy( myVec.begin(),myVec.end(),ostream_iterator<int>( cout," " ));
    cout<<endl;
    const vector<int>::iterator cite = myVec.begin();
    *cite = 10; //可行
    //++cite; //错啦错误
    copy( myVec.begin(),myVec.end(),ostream_iterator<int>( cout," " ));
    cout<<endl;
    vector<int>::const_iterator icte = myVec.begin();
    // *icte = 100; //error C3892: “icte”: 不能给常量赋值
    ++icte; //可行
    copy( myVec.begin(),myVec.end(),ostream_iterator<int>( cout," " ));
    cout<<endl;
    return 0;
}
