首先说一下基本优先级

 

 1)括号永远优先级最高

 2)无括号的默认优先级

 * / 运算优先级最高

 % 运算优先级次高

 + -运算优先级最低

 

 然后来看算式:

 a+(int)(b/3*(int)(a+c)/2)%4

 =2.5+(int)[7/3*(int)(2.5+4.7)/2]%4         --①代入变量值,中括号为了表达优先级

 =2.5+(int)[7/3*7/2]%4                            --②(int)(2.5+4.7)=(int)7.2=7

 =2.5+7%4                                              --③(int)[7/3*7/2] 因为是int型数字进行运算

                                                               --所以所有运算结果去掉小数点后面的部分

                                                               --(int)[7/3

24 As Godbey points out, the stress we feel arises not from a shortage of time, but from the surfeit of things we try to cram into it. 'It's the kid in the candy store,' he says. 'There's just so many good things to do. The array of choices is stunning. Our free time is increasing, but not as fast as our sense of the necessary.'

Some people seem easy to understand: their character appears obvious on first meeting. Appearances, however, can be deceptive.

For thirty years now I have been studying my fellowmen. I do not know very much about them. I shrug my shoulders when people tell me that their first impressions of a person are always right. I think they must have small insight or great vanity. For my own part I find that the longer I know people the more they puzzle me.

These reflections have occurred to me because I read in this morning's paper that Edward Hyde Burton had died at Kobe. He was a merchant and he had be

The mere fact that America still attracts millions of people is evidence that it is not in decline.People aren't attrcted to a place of decline. Signs of decline are sure to be found in a placeas complex as America :debt, crime, the homeless,drugs,dropouts.But the main characteristic of America ,the first and most enduring（持久的,）impression（印象）is dynamism（活力、精力）,energy,aggressiveness,forward movement.

It is so hard to think of this nation in decline when you know that there are vast regions of the planet which are absolutely paralyzed（瘫痪的），incapable of any improvement at all.

It is difficult for me to agree with Pual Kennedy'sthesis（论题，论点）in The Rise and Fall of Great Powers that America must inevitably（必然的，不可避免的）follow historical precedent（先例）.That's the w
