what is difference between ++i and i+=1 from any point of view

Question

This is a question from kn king\'s c programming : a modern approach. I can\'t understand the solution given by him:-

The expression ++i is equivalent to (i          


        

Answer 1

One difference that has not been brought up so far is readability of code. A large part of loops use increment by one and common practice is to use i++/++i when moving to the next element / incrementing an index by 1.

Typically i+= is used in these cases only when the increment is something other than 1. Using this for the normal increment will not be dangerous but cause a slight bump in the understanding and make the code look unusual.
