Increase vector with while loop

[amanseau]

I want to be able to have the numberSorting.at increase with each loop, but I can't figure out how to do that. Any suggestions?

 #include "pch.h"
#include <iostream>
#include <vector>
#include <string>
#include <algorithm>

using namespace std;

int amountNum;
int i = 0;

int main()
{
	cin >> amountNum;
	vector<int> numberSorting(amountNum);
	while (i < amountNum) {
		cin >> numberSorting.at();
		i++;
	}

	return 0;
}

numberSorting.at(i)

Thank you!
