解析 正确答案:8,20 解析:本题考查while循环和++运算符的运用。x=O符合条件x<15,则执行y++,x+=+y后,y=1,x=0+2=2后y=2,符合条件继续循环,y=3,x=x+4=6后y=4,再循环y=5,x=x+6=6+6=12后,y=6,继续循环y=7, x=x+8=12+8=20,此时y=8。
x+=++y得到y=2,x=2 第二次循环 y++得到y=3 x+=++y得到y=4,x=6 第三次循环 y++得到y=5 x+=++y得到y=6,x=12 第四次循环 y++得到y=7 x+=++y得到y=8,x=20 循环结束
x = 12时，执行y++后，y = 7，执行x += ++y后，y = 8，x = 20 不满足x < 15，退出循环，故输出是8,20

While作为并列连词，意思为而，然而，表前后意义上的对比或转折。(x=y)5是5X=5Y是一个数学方程式。
因为y++，x+=++y;是逗号表达式，所以最终值是x+=++y;还有x+=++y等价于x=x+(++y)0<15 y=1,x=0+2;//x=2,y=2 2<15 y=3,x=2+4;//x=6,y=4 6<15 y=5,x=6+6;//x=12,y=6 12<15 y=7,x=12+8;//x=20,y=8 20<15 不成立 输出：y=8,x=20 ...
