D: -49
A: -50

D: -49
举一反三
- $sum = 0; for($i=1；$i<=100;;++$i){ if($i%2==0){ continue; } $sum += $i; } echo '$sum ='.$sum; echo输出值为_______。 2、 $sum = 0; for($i=1；$i<=100;;++$i){ if($i%2==0){ continue; } $sum += $i; } echo '$sum ='.$sum; echo输出值为_______
- 如下程序实现了1-100的累乘计算sum = 0for i in range(1,101): sum+=iprint(sum)
- 在下列程序段中，不能计算1到100之间奇数之和的是__________。 A: Dim sum As Integer sum = 0 For i = 1 To 100 Step 2 sum = sum + i Next B: Dim sum As Integer sum = 0 For i = 1 To 100 If i Mod 2 <> 0 Then sum = sum + i Next C: Dim sum As Integer sum = 0 For i = 1 To 99 sum = sum + i Next D: Dim sum As Integer sum = 0 For i = 100 To 1 Step -1 If i Mod 2 <> 0 Then sum = sum + i Next
- def func(): global sum sum=0 print(sum) for i in range(5): sum+=1 print(sum) func() print(sum)
- 下述程序的执行结果为sum = 0for i in range(100): if(i%10): continue sum+=1print(sum)
