Answer 3

I would just like to mention that the code

int n; cin >> n; int array[ n ];

is not exactly standardized C++. Variable-length arrays are a part of C as of C99, but haven't been introduced to the C++ standard. Most compilers will support the construct as a language extension, but I don't think you should rely on this.
The "proper" way would be to either use dynamic memory allocation:

Or just to use std::vector:

Answer 7

Jayakrishna Nothing besides what I have already mentioned. Just wanted to point out that it, although working, is not pure standard C++, and therefore should be avoided from my perspective, that's all.
