Hi, I was wondering if anyone could help me. I'm constantly getting the following compiler message:

138 driver.cpp 'class pclass' has no member named 'surname'
138 driver.cpp 'class pclass' has no member named 'name'

on the following lines:

138 for (i = person[surname][name].begin(), i != person[surname][name].end(), ++i) {
139   for (iter = person[*i.first][name].begin(), iter != person[*i.first][name].end, ++iter) {

i and iter are iterators that have to loop through the contents of a two dimentional map named person using a nested for-loop. They are defined as follows:

typedef map<string, map<string, Person_class> > pclass;
pclass::const_iterator i;
map<string, Person_class>::const_iterator iter; 
pclass person;

and the definition for the Person_class defined in the header file:

//Person class declaration
class Person_class {


       //Accessor Functions

       std::istream& read_surname(std::istream&);
       std::istream& read_name(std::istream&);
       std::istream& read_phone(std::istream&);
       std::istream& read_age(std::istream&);
       std::istream& read_weight(std::istream&);
       std::string get_name() const { return name; }
       std::string get_surname() const { return surname; }
       std::string get_phone() const { return phone; }
       int get_age() const { return age; }
       double get_weight() const { return weight; }

       //Constructor Functions



        std::string surname;
        std::string name;
        std::string phone;
        int age;
        double weight;

I'm only getting the error on line 138 though, but that's maybe because the compiler ignores the rest of the for-loop...

I thought the reason for the errors could be the fact that surname and name are private sections of the Person_class, but replacing them
with the get_surname() and get_name() functions like :

138 for (i = person[person.get_surname()][person.get_name()].begin(), i != person[surname][name].end(), ++i) {
139 for (iter = person[*i.first][person.get_name()].].begin(), iter != person[*i.first][person.get_name()].].end, ++iter) {

yield the following compiler errors:

138 driver.cpp 'class pclass' has no member named 'get_surname'
138 'class pclass' has no member named 'get_name'

I'm using Dev C++ on Windows XP(Service Pack 2)

Here's a copy of the first few lines of my compiler log:

Compiler: Default compiler

driver.cpp:138: error: 'class pclass' has no member named 'get_surname'

If anybody could please help me out, that would be awesome...

'person' is a map of maps, not a Person_class, so naturally it won't have those members. person["somestring"]["somestring"] would return (or set) a Person_class, however, so trying:


Wouldn't make sense (Person_class doesn't have a begin() method). I suppose you could do (untested):

for (i = person.begin(); i != person.end(), ++i) {
  for (iter = i->begin(), iter != i->end(), ++iter) {

I'd like to suggest more of a solution, but I really have no idea what you're trying to do (and if you need to iterate over the entire "person" container, a map might not be the best solution)
