i need a quick help plz..(Hash class)

[eng soso]

im writing a HW a bout universal hashing H=((ak+b)%p)%n) with chaining
but i got a lot of errors & it's making me crazy plz help me to solve errors

#include<iostream>
#include<math.h>
using namespace std;

// class node
class node{
public:
int id;
char * name;
char * address;
int age;
node * next;
int GPA;
node(int num,char * nam,char * addr,int ages,int gpa){
	id = num;
	name = nam;
	address = addr;
	age = ages;
	GPA = gpa;}

};

// class Hash
class hash{

public : hash();
		 hash(int aa,int bb,int prime,int size);
		 ~hash();
		 int hashfunc(int key);
		 bool insert(node *n);
		 bool retrieve(int id2,node *nn);
		 bool remove(int id3);
		 double getloadfactor();
 int a ;int b;int p; int n;
}
// constructers
hash::hash(){
	a=23;b=88,n=100,p=997;
	int * *table;
	for(int i=0;i<n;i++){
	table [i]=NULL;}

};

hash::hash(int aa,int bb,int prime,int size){

	a=aa;b=bb;p=prime;n=size;
	int **table;
	for( int i=0;i<n;i++){
	table [i]=NULL;}

};

//destructers

hash::~hash(){
	node *p;
	for(int j=0;j<n;j++)
		while (table[j]!=NULL){
				p=table[j];
			table[j]=table[j]->next;
			delete p;}
			delete []table[j];
};

// hashing function
int hash::hashfunc(int key){
	int H=((a*key+b)%p)%n;
	return H;
}
// retrieve function
bool hash::retrieve(int id2,node *nn){
int s=hashfunc(id2);
bool done=true;
if(table[s]==NULL)done=false;

else{node *pp=table[s];
while(pp!=NULL && !done){
	if(pp->id==id2)
	{memcpy(nn,table[s],sizeof(node));
	done = true;
		else pp=pp->next;

	}
// insert function
	bool hash::insert(node *n){
		int F=hash(n->id);
		if(table[F]==NULL){
			table[F]=n;
			done=true;}
		else{
			n->next=table[F];
			table[F]=n;
		}
		return done;
	}
// remove function
	bool hash::remove(int id3){
		node *p1,*p2;
		p1=p2=table[m];
		int m=hashfunc(id3);
		if(table[m]==NULL)done=true;

		else if(table[m]->id==id3){
			node *v=table[m];
			table[m]=table[m]->next;
			delete v;
			done =true;
		}
		else {
			while(p2!=NULL){
				if(p2->id==id3){
					p1->next=p2->next;
					delete p2;
					done = true;
				}
				else{ p1=p2;
				p2=p2->next;}
			}
		}
		return done;
	}
// load function
	double hash::getloadfactor(){
		double count=0;
		for(int u=0;u<n;u++){
			if(table[u]!=NULL){
				node *e=table[u];
				while(e!=NULL){
					count++;
					p=p->next;}
			}
		}
		return count/size;
	}

here the errors i got

Add a semicolon on line 35
table should probably be a member variable.
I also get errors saying that the reference to hash is ambiguous. It's because you use using namespace std; so it doesn't know if you mean ::hash or std::hash when you write hash.

thx peter for replaying .. i really don't understand ur last note .. i fixed wt u said but i still get those errors :(

Shouldn't table be of type node**?

[eng soso]

the idea is to make an array of pointers & when a collision occer i solve it by chaining using link list ..do u have another idea ..i actually don't know how to make the table member can u help me with the code ?!
