This is the code in VS:

int main(){ 
    int hi = 5;
    int arr[hi]{};
}

The error:

Error(active) E0028 expression must have a constant value

The same code in code::Blocks:

int main() {
    int hi = 5;
    int arr[hi]{};
}

There is no error.

So, how can I run this code normally in VS without changing anything in the syntax?
