[SOLVED] Declaring a Vector inside a C++ Class

Aquarius_Girl · 03-23-2010, 12:19 AM

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 ..
