It's years and years that the only use of postfix operators I do that is not alone in the row (so that isn't. So i will increment first and the incremented value is assigned to j Here i and j both become 6.

What is the best way to iterate over a dictionary? The way the operator works is that it gets incremented at the same time, but if it is before a variable, the expression will evaluate with the incremented/decremented variable: If it is after the variable the current statement will get executed with the original variable, as if it had not yet been incremented/decremented: I agree with dcp in using pre-increment/decrement (++x) unless necessary. There’s common confusion between the difference of the Prefix (++i) and Postfix (i++) increment operators in C#. Is the bullet train in China typically cheaper than taking a domestic flight? The sequence of events in time is extremely well-defined in C#, and it is emphatically not the case that the prefix (++var) and postfix (var++) versions of ++ do things in a different order with respect to other operations. The numerical value of c.i.s. Counting monomials in product polynomials: Part I. 9.7 (i.e. Updated July 2020. This leads people to write dangerously nonportable code that works on some compilers and does something completely different on others. That means both i++ and ++i will be equivalent. IT vs ICT . GSO vs GSO satellite networks) The ROP defines . "Don't make me think" applies to code as well as design. What factors promote honey's crystallisation? Also, we run into similar subtle issues when considering other operations that have side effects, such as chained simple assignments: https://docs.microsoft.com/archive/blogs/ericlippert/chaining-simple-assignments-is-not-so-simple. Oddly it looks like the other two answers don't spell it out, and it's definitely worth saying: i++ means 'tell me the value of i, then increment', ++i means 'increment i, then tell me the value'.

What is the difference between C++0x and C++11? @gnovice, the first one asks about performance difference while I asked about the actual code-wise difference, the second is about the difference in a loop while I asked the difference in general, and the third is about C++.
