c++ - copying c array of strings into vector of std::string

I need to store elements of a c array of strings in a vector.

Basically I need to copy all the elements of a c array into a vector<std::string>.

#include<vector>
#include<conio.h>
#include<iostream>

using namespace std;

int main()
{
    char *a[3]={"field1","field2","field3"};

    //Some code here!!!!

    vector<std::string>::const_iterator it=fields.begin();
    for(;it!=fields.end();it++)
    {
        cout<<*it++<<endl;
    }   
    getch();
}

Could anybody help me out to store c array elements into a vector?

EDIT

this below code is dumping the core!!Pls help

int main()
{
    char *a[3]={"field1","field2","field3"};
    std::vector<std::string> fields(a, a + 3);

    vector<std::string>::const_iterator it=fields.begin();
    for(;it!=fields.end();it++)
    {
        cout<<*it++<<endl;
    }   
    getch();
}
