Stack Exchange: Code Review - Julia's new school

Nov. 24, 2016

Julia started her first day to look into stack exchange: code review, and then, she joined one of discussion - quicksort, she was amazed how she learned quickly in the place.

Her first reading starts from here:

http://codereview.stackexchange.com/questions/5648/any-way-to-make-this-recursive-function-better-faster/5661?newreg=7b2fea2453a54c15bc466355fea0891d

Julia also wrote a blog about quick sort in 2016:

Compilers Job

Don't do work the compiler can do for you:

int arr[8] = {110, 5, 10,3 ,22, 100, 1, 23};

The compiler is better than you at it anyway and it will prevent errors. Here you have said the number of elements is 8. As a human I can't see that at a glance I could count them to verify but as a human I am lazy and going to assume you got it correct. If you did not get it correct then we will have problems.
So let the compiler work it out.

int arr[] = {110, 5, 10,3 ,22, 100, 1, 23};

Now if the array changes size you only have to change one thing (the data). Rather than two things (data and size).
