Firstly, the variable ident is actually declared by its visual appeal during the loop, It's really a new variable which exists for that scope of the loop only and normally takes the correct sort based on the specified vary.
The primary is the self-assignment test. This Test serves two needs: It is really an easy way to avoid us from working needless code on self-assignment, and it safeguards us from delicate bugs (for example deleting the array only to try and replica it).
We lose a crucial optimization prospect. Not merely that, but this decision is significant in C++eleven, which happens to be discussed later on. (On a typical Notice, a remarkably useful guideline is as follows: if you are going to produce a duplicate of a little something in the perform, Enable the compiler do it in the parameter listing.‡)
