Hi all, I have two questions. Can some one give some help? The first question is regarding the pair of operators "&" and "&&". What is the difference between the two?
The second question is regarding "<-" and "=". Usually we use "<-" as the assignment operator. I saw some people use "=". Is there any difference between the two. Thank you!!
