Declaring a Vector inside a C++ Class

Is it not possible to declare a vector inside a C++ class ?

Have a look at the following code:

Code:

#include <stdio.h>

#include <iostream>

#include <malloc.h>  // malloc

#include <strings.h> // bzero

#include <string.h>  // memcpy

#include <vector>



using namespace std;



class packedMessage

{

        protected:

                vector <unsigned int> numberOfBitsToBeExtractedVec;

                vector <numberOfBitsToBeExtractedVec> :: iterator numberOfBitsToBeExtractedIter;

        public:

                packedMessage  ();

                ~packedMessage ();

};



int main () {return 0;}

It is giving me the following errors:

Code:

vk.cpp:13: error: invalid use of non-static data member ‘packedMessage::numberOfBitsToBeExtractedVec’

vk.cpp:14: error: from this location

vk.cpp:13: error: invalid use of non-static data member ‘packedMessage::numberOfBitsToBeExtractedVec’

vk.cpp:14: error: from this location

vk.cpp:14: error: ‘packedMessage::numberOfBitsToBeExtractedVec’ cannot appear in a constant-expression

vk.cpp:14: error: template argument 1 is invalid

vk.cpp:14: error: template argument 2 is invalid

vk.cpp:14: error: expected ‘;’ before ‘numberOfBitsToBeExtractedIter’

What's wrong here ?

A quick look at you code would suggest to me that your iterator is set up incorrectly. It should probably be

Code:

vector<unsigned int>::iterator nobIter;

I don't know how to thank you for pointing out this senseless mistake to me ! I wish one could click thanks button more than once ..
