"*="是如何运算的?

[WxmJun]

int i=0,D_PAGE_SIZE=20;

i *= D_PAGE_SIZE +1;
结果0
i =i * D_PAGE_SIZE +1;
结果1

i=1;
i *= D_PAGE_SIZE +1;
结果21
i =i * D_PAGE_SIZE +1;
结果21

"*="是如何运算的?害我找了半天.才找到这个错误.

[ntzls]

i *= D_PAGE_SIZE +1;

==> i = i*(D_PAGE_SIZE +1);

[qqbz]

i *= D_PAGE_SIZE +1；<-> i *= i *(D_PAGE_SIZE +1);

[WorkJava]

int i=0,D_PAGE_SIZE=20;

i *= D_PAGE_SIZE +1;<=>int x,y; x=D_PAGE_SIZE +1;(x=21) y=i*x;(y=0);i=y;(i=0)
<=> i = i*(D_PAGE_SIZE +1);

[wildleon]

i*=表达式;<=>i=表达式*i;

不是吧，楼主这个都？？？

[panzhiwei]

例如
A=5;
A*=5
现在的A等于25;
也就是先把A的值乘5在把乘后的值付给A
