使用变量year代表年份,以下表示判断year是否为闰年的布尔表达式是 。
A: (year % 4 == 0) and (not(year % 100 == 0)) or (year % 400 == 0)
B: (year % 4 == 0) and (not(year % 400 == 0)) or (year % 100 == 0)
C: (year % 4 == 0) and (year % 100 == 0) or (year % 400 == 0)
D: (year % 4 == 0) or (not(year % 100 == 0)) and (year % 400 == 0)
A: (year % 4 == 0) and (not(year % 100 == 0)) or (year % 400 == 0)
B: (year % 4 == 0) and (not(year % 400 == 0)) or (year % 100 == 0)
C: (year % 4 == 0) and (year % 100 == 0) or (year % 400 == 0)
D: (year % 4 == 0) or (not(year % 100 == 0)) and (year % 400 == 0)
举一反三
- 判定year是否为闰年的表达式是 A: year % 400 == 0 or year % 4 == 0 and year % 100 <> 0 B: year % 400 == 0 or year % 4 == 0 , year % 100 != 0 C: year % 400 == 0 or year % 4 == 0 and year % 100 != 0 D: year % 400 == 0 or year % 4 == 0 , year % 100 <> 0
- 题:(拓展)下面哪些表达式能够判断某年year不是闰年。 A: not(( year%4==0 and year%100 !=0 ) or ( year%400==0 )) B: not( year%4==0 and year%100 !=0 ) and not ( year%400==0 ) C: year%4!=0 or year%100 ==0 and ( year%400 !=0 ) D: year%4==0 and year%100 !=0 or ( year%400==0 )
- 判断某年是否为闰年的表达式正确的是()。 A: year%4==0&&year%100!=0||year%400==0 B: year%4==0&&year%100=0||year%400!=0 C: year%4!=0&&year%100!=0||year%400==0 D: year%4==0&&year%100==0||year%400==0
- 判断year变量为闰年的表达式为()。 A: year%4==0&&year%100!=0&&year%400==0 B: year%4==0||year%100!=0&&year%400==0 C: year%4=0&&year%100<;>;0||year%400=0 D: year%4==0&&year%100!=0||year%400==0
- 用变量year表示某一年,判别不是闰年的逻辑表达式有( ). A: (year%4||!(year%100))&&year%400 B: 61519 C: (year%4==0&&year%100!=0)||year%400==0 D: !((year%4==0&&year%100!=0)||year%400==0) E: (year%4!=0||year%100==0)&&year%400!=0
