int numList1[10];

int *numList2 = new int[10];

I have seen too many solutions from others used the second way to assign array, do they work as the same?

    The first one is on the stack the second one is on the heap and will therefore leak memory unless `delete` is used, but I advise you to read some good C++ learning resource since this is very basic C++ – Lala5th Apr 12 '22 at 00:36

    use std::array for the first one and std::vector for the second one – pm100 Apr 12 '22 at 00:40

    Your terminology is wrong. In neither case in an array being assigned. In the first an array is being defined. In the second a pointer is being defined and being initialized. [You cannot actually assign an array in C++](https://stackoverflow.com/questions/18962441/assign-array-to-array), but you can with `std::array` and `std::vector` – user4581301 Apr 12 '22 at 00:50

    thank you for the comments. It is so painful to study c++ from the internet, they always jump to another unknown section suddenly and I can't catch it... – Sloth Cheung Apr 12 '22 at 01:04
