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
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
举一反三
- 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
- 某一年year是否闰年的表达式为() A: (year%4==0&&year%100!=0)||year%400==0 B: year%4==0 C: year%4==0&&year%100!=0 D: year%4==0||year%400==0
- 判断为闰年的正确条件为: A: year%4==0&&year%100!=0 B: (year%4==0&&year%100!=0)&&(year%400==0) C: year%400==0 D: (year%4==0&&year%100!=0)||(year%400==0)
- 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
- 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)
