NettetIn many of the mock SCJP exams the following type of question occurs int x, a = 6, b = 7; x = a++ + b++; After execution of the code fragment above what are the values of x,a and b The answer given is always a = 7, b= 8 and x = 13 This is because x is evaluated as a+b and then a++ and b++ are evaluated. I don't understand why! Nettet31. aug. 2024 · 1、a++:先返回值a,再执行a=a+1; （先赋值再自加） 如：int a=3; b=a++; 运算结果为： a=4; b=3; 2、++a:先执行a=a+1,再返回值a;（先自加再赋值） 如：int a=3; b=++a; 运算结果为： a=4; b=4; 在c中，++有前置和后置如 ++a;a++;，单独使用的时候是没有区别的，都是自加1，在有运算时就有区别了，前置的++是自加后才参与运算，后置 …

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. crack stream fight https://makendatec.com
