This function is used getline function to get data. The data is stored
as String. I want to add it in a linked list. However, the strcpy that I
 have pointed cause the program segementation fault. What I can do to
add the item in the linked list and it don't need to change the Linked
list ADT item type ?

void load(istream& is, Position p, List * r )

    string temp_name;

        //get the restaurant name in restaurnat.txt
        while ( getline(is, temp_name, '\n')) {
        
        char *name;

        //change type of name of restaurant from string to char
        name = new char[temp_name.length() + 1 ];
        strcpy( name, temp_name.c_str()); <-- This one

        char *namet;

    p = ListHead(r);
    namet = (char *)malloc(sizeof(name));
    strcpy (namet, name);

    //Add the namet in the linked list
    if (!rest_get_name(r, p, namet)) {
        exit (EXIT_FAILURE);
    }
