Answer 1

You did not declare nums, try this it will take the length and the array from the user

#include <iostream>
using namespace std;

int main() {
int n;

cin>>n; //size of the array
int nums[n];
for(int i=0; i<n; i++) {
cin>>nums[i];
}
int max = nums[0];
for(int i=0; i<n; i++) {
if(nums[i]>max)
max = nums[i];
}
cout << max;

return 0;
}

Yes it works but i want to try like
int *ptr = new int;
Something like this if you have any idea.

Answer 3

maybe like that?

#include <iostream>
using namespace std;

int main() {
int n;
int * nums;
cin>>n; //size of the array
// your code goes here
nums = new int[n];

for(int i=0; i<n; i++) {
cin>>nums[i];
}

int max = nums[0];
for(int i=0; i<n; i++) {
if(nums[i]>max)
max = nums[i];
}
cout << max;

return 0;
}
