Question

I’m trying to do a loop for this part:

    insert_front(&list,name[0]);
    insert_front(&list,name[1]);                 
    insert_front(&list,name[2]);

but, i can’t figure out which should be used as a limiter, which should stop the loop for going and how it will change the name[] perimeters.

Here’s the whole code:

#include "list.h"
#include "string"
using namespace std;
int main(){
    cout<<"What is your name \n";
    string name;
    getline(cin,name);

    Node *list;

    list = new_list();                          
    insert_front(&list,name[0]);
    insert_front(&list,name[1]);                  
    insert_front(&list,name[2]);
    }                          
    print_list(list);                                      
    delete_list(&list);
        print_list(list);
        return 0;

}

Iterator version (C++03):

for (std::string::iterator iter = name.begin(); iter != name.end(); ++iter)
    insert_front(&list, *iter);

Foreach version (C++11):

for ( char c : name)
    insert_front(&list, c);

Index version (C++03):

for (size_t i = 0; i < name.size(); ++i)
    insert_front(&list, name[i]);

Foreach version (C++03 with Boost):

std::for_each(name.begin(), name.end(), boost::bind(insert_front, &list, _1));

I’m not so sure on the C++11 foreach version.

There’s probably also a reasonable way to use std::copy or std::transform if your hand-coded list has iterators.
