Stuck on 33.2 challenge, dynamic memory

Question

Hey peeps,
I understand how you can input the array size (n) and then input each value, but I’m having difficulty linking that to the given code in the challenge- which selects the maximum value of the values.
This code is as far as I can get without my brain hurting 🤪
#include <iostream>
using namespace std;
int main() {
int n;
int *ptr;
cin>>n;
ptr = new int[n];
for(int i=0;i<n;i++)
{
cin>>ptr[i];
int max = nums[0];
for(int i=0; i<n; i++) {
if(nums[i]>max)
max = nums[i];
}
cout << max;
}
return 0;
}

Answer 1

(1) You're nesting for loops, which I don't think you've noticed.
for(int i=0;i<n;i++)
{
cin>>ptr[i];
} <- Missing
And there is an extra brackets before return 0.
(2) nums[] does not exist, ptr[] does.
(3) You did not delete ptr at the end of the code.

thank you so much!
