以下函数中,运算结果为1的是()
A: =COUNTA(0,1,2)
B: =COUNT(O,1,2)
C: =COUNT(1)
D: =COUNT("1","a","b")
E: =COUNTA("1","a","b")
A: =COUNTA(0,1,2)
B: =COUNT(O,1,2)
C: =COUNT(1)
D: =COUNT("1","a","b")
E: =COUNTA("1","a","b")
举一反三
- 下列函数中,用于单个条件统计的函数是() A: countif(范围1,条件1) B: countifs(范围1,条件1,范围2,条件2,......) C: count(范围1) D: counta(范围1)
- 下列函数中,可以进行多条件统计的函数是() A: counta(范围1,范围2, ...) B: countif(范围1,条件1) C: count(范围1) D: countifs(范围1,条件1,范围2,条件2,......)
- count目前的值是1,请问执行复合赋值语句 count += 1 后,count的值是多少? A: 0 B: 1 C: 2 D: 3
- The output of the following code is ____.<br/>count = 1; /* initialize count */ while (count <= 10) { printf("%d ",count); count++; /* increment count */ } A: 1 1 1 1 1 1 1 1 … B: 1 2 3 4 5 6 7 8 9 C: 1 2 3 4 5 6 7 8 9 10 D: 1 2 3 4 5 6 7 8 9 10 11
- 执行下述代码: count = 5 def print_num(): count = 2 count += 1 print(count) 当调用print_num()函数时,输出结果为( )
