How do the post increment (i++) and pre increment (++i) operators work . . . 3 Pre-increment means that the variable is incremented BEFORE it's evaluated in the expression Post-increment means that the variable is incremented AFTER it has been evaluated for use in the expression Therefore, look carefully and you'll see that all three assignments are arithmetically equivalent
Incrementing in C++ - When to use x++ or ++x? - Stack Overflow This may seem like pedantry (mainly because it is :) ) but in C++, x++ is a rvalue with the value of x before increment, x++ is an lvalue with the value of x after an increment Neither expression guarantees when the actual incremented value is stored back to x, it is only guaranteed that it happens before the next sequence point 'after processing the current statement' is not strictly
Post-increment and pre-increment within a for loop produce same . . . Because in either case the increment is done after the body of the loop and thus doesn't affect any of the calculations of the loop If the compiler is stupid, it might be slightly less efficient to use post-increment (because normally it needs to keep a copy of the pre value for later use), but I would expect any differences to be optimized
