I have to write a program where the user will input integer numbers. How many numbers they enter is unknown, therefor you should use a repetition structure for the input. When the user is done, they will enter -1 to exit.
Create a dynamic array if the size=2( the initial size must be 2)
Repeat until user enters -1.
I have to do this without using vectors.
This is what i have, I cannot figure out what to put in main. I was thinking of a do-while?
This is my first time in c++
Any hints?

Code:
#include <iostream>
using namespace std;
void resize(int *[], int);
int main()
{
int *listDyn;
int size=2;
listDyn=new int[size];
for (int i=0; i<size; i++)
{
cout << "Enter as many integers as you'd like or enter -1 to exit" ;
cin >> listDyn[i];
}
void resize(int *listDyn, int size)
{
int *listDynNew=new int[size*2];
for (int i=0; i<size; i++)
listDynNew[i]=listDyn[i];
size++;
listDyn=listDynNew;
delete[] listDynNew;
}
