Nettet16. jun. 2008 · 答案是:22 分析: char a='1'b='2'; //赋值,注意a b的类型为char printf ("%c",b++); //以字符型打印打印b后b才自加,所以是现打 //印出“2”后 //b的ASCII码值是50,自加后是51 printf ("%d\n",b-a) //这句是b的ASCII码值减去a的ASCII码值后 //以整型输出,即51-49=2,所以输出“2” 85 评论 (5) 分享 举报 lich2000 2008-06-16 · 超过20用户 … Nettet7. aug. 2013 · 0. It would seem that having a sequence point is immaterial in the expression b=++a + ++a; That is, whether the first ++a is evaluated first or the second … NettetThe answer is no; proof follows. Assume without loss of generality that a ≤ b ≤ c. If a ≥ 2, then the expression is at most (3/2)3 < 4, a contradiction. Hence a = 1, and we rewrite … auto oy vesa matti vaihtoautot
