wont let me create a vector of my user defined class
 

This is for a frequency table that will eventually allow me to build a Huffman coding tree. I want the class FrequencyTable to simply hold a vector of the type FrequencyNode however I keep getting an error about ISO forbiding the creation of the vector. Any ideas why?
Error:

FrequencyTable.h:11: error: ISO C++ forbids declaration of ‘vector’ with no type

Class FrequencyNode

#ifndef FREQUENCY_NODE_H

#define FREQUENCY_NODE_H



#include <iostream>

#include <stdlib.h>

#include <string>



class FrequencyNode {

private:

        int frequency;                        //Key

        char character;                //Element



public:

        FrequencyNode()                                                                                                        //default constructor

                :character(0) {}                                                                                                

        FrequencyNode(int freqParam, char charParam)                         //constructor

                :frequency(freqParam), character(charParam) {}                



        int getKey() { return frequency; }

        char getChar() { return character; }

        

        int incrimentKey() { frequency++; }

Thanks

Re: wont let me create a vector of my user defined class
 

The vector class is in the std namespace. Change

vector<FrequencyNode> list;

to

std::vector<FrequencyNode> list;

. You have other errors though.

that worked thanks. Ya i know about the others. Im working on them now.
