Nettet25. sep. 2016 · int a = 10; int b = 2; b = a+++a; System.out.println(a+","+b); it printed out 11,21. I think the way java do that is it find first a ++ and use 10 in for now, but increase it immediately afterward (before evaluating the second a), and when adding the second a, it is already 11, which gives b = 21. When I tried that on GCC, it gives 11, 20. Nettet后置a++相当于做了三件事情： 1. tmp = a; 2. ++a 3. return tmp; 事实上，如果这里a是一个对象，而非一个基本类型数据的话，我们重载其后置自增运算符就分成上述三个步骤（ …

"NettetWorking. The value of a is 20 and b is 16. The condition (a > 10) is true, so the execution enters the if block. The statement a = a++; increments the value of a by 1 after the assignment. So a remains unchanged as we are assigning the original value of a (which is 20) back to a. The value of b is incremented by 1 so b becomes 16. Answered By. " - Int b a++ + a++
