pointers

[clomer]

hello Ive been trying to learn pointers and Im having a hard time with them, after doing all the exercises from various websites and searching through posts Im still none the wiser really, my little pointer exercise program is not changing the value of an array of struct im sending it.

Where am I going wrong.

#include <iostream>
#include <conio.h>

using namespace std;

struct mystruct{
	int number;
	char name;
};

int passmypointer(int p, int l);
void changemyarray(int *pointer, int size);
void changemystruct(int *arraypointer, int size);


int main()
{
	mystruct myarraystruct[10];
	for (int i = 0; i < 10; i++){
		myarraystruct[i].number = i + 1;
		myarraystruct[i].name = 'A';
	}

	for (int i = 0; i < 10; i++)
		cout << myarraystruct[i].number << "  " << myarraystruct[i].name << endl;

	int *myarraypointer;
	myarraypointer = new int[10];
		if (myarraypointer == '\0')
			exit(0);
		else
			for(int i = 0; i < 10; i++)
				myarraypointer[i] = i * i;

		for(int i = 0; i < 10; i++)
			cout << myarraypointer[i] << "  " << &myarraypointer[i] << endl;

	int *p;
	int **l;
	int ***z;
	int n = 2523;
	int v = 450;
	int end = 101011;
	cout << "Address of V : " << &v << endl;
	cout << "Value of n   : " << n << endl;
	cout << "Address of n : " << &n << endl;

	p = &n;

	cout << "Value of *p   : " << *p << endl;
	cout << "Address of p  : " << &p << endl;

	

	l = &p;

	cout << "Value of **l   : " << **l <<endl;
	cout << "Address of l  : " << &l << endl;

	

	cout << "Value after passing  :" << passmypointer(**l, *p) << endl;

	cout << "Value after function :" << **l << endl;

	z = &l;

	cout << "Z = " << ***z << endl;

	int *y;
	y=&v;

	
	cout << "Address of *y :" << &y << endl;

	cout << "Value pointed to by *y :" << *y << endl;

	cout << endl << "Point at something else " << endl << endl;

	p = &end;
	y = &end;
	*l = &end;

	cout << "P = " << *p << " Address = " << &p << endl;
	cout << "Y = " << *y << " Address = " << &y << endl;
	cout << "l = " << **l << " Address = " << &l << endl;

	changemyarray(myarraypointer,10);

	cout << "After passing my array" << endl;
	for(int i = 0; i < 10; i++)
			cout << myarraypointer[i] << "  " << &myarraypointer[i] << endl;

	cout << "After passing my struct" << endl;
	changemystruct(myarraystruct,10);
	for (int i = 0; i < 10; i++)
		cout << myarraystruct[i].number << "  " << myarraystruct[i].name << endl;

	getch();
	return 0;


}

int passmypointer(int p, int l)
{
	return p + l;
}

void changemyarray(int *pointer, int size)
{
	for(int i = 0; i < size; i++)
				pointer[i] = 0;


}

void changemystruct(int *arraypointer, int size)
{
	for(int i = 0; i < size; i++){
				arraypointer[i].number = 0;
				arraypointer[i].name = 'B';
	}
	

}

Error Im getting is

Thank you.

struct mystruct{
	int number;
	char name;
};

int passmypointer(int p, int l);
void changemyarray(int *pointer, int size);
void changemystruct(int *arraypointer, int size); //<<====  

.....
//skip a lot of stuff here

void changemystruct(int *arraypointer, int size)//<<=====
{
	for(int i = 0; i < size; i++){
				arraypointer[i].number = 0;
				arraypointer[i].name = 'B';
	}
	

}

Check carefully - is int* the correct type for the first parameter ????

A eureka moment, mystruct is my int thanks alot.
