Is there any difference between a+=1 and a=a+1?(although i think it's the same I want to know if there's any exception )

Answer 1

a+=1 is the exact same as a=a+1, and is used just a shorter way of writing it (I can't really think of any situation where you would need to use a=a+1 rather than a+=1, so I would just recommend sticking with the latter as writing the least amount of code is always your best option.

Answer 2

Its the same!

Answer 3

The difference is one character in the source code discounting white space.

Answer 4

If incrementing by 1 just use ++ ... otherwise use += ... or varname = varname + num. Not sure if there's a difference in performance from one over another. Careful here too... note that using + can also concatenate strings. So be sure what you are incrementing is a number.
