1、判断是否闰年的表达式(如果是闰年则值为1,否则为0)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))

判断闰年的函数,把下列语句补充完整。 leap.year <- function (year) { ifelse (, TRUE, FALSE) }A.(year %% 4 == 0 year %% 100 != 0)B.(year %% 4 == 0 year %% 100 != 0) || year %% 400 == 0C.(year %% 4 == 0 || year %% 100 != 0)D.(year/4 == 0 year/100 != 0) || year/400 == 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)
