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
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
C
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_______
- 执行循环后，两变量 I, Sum 分别是： Dim I As Short = 1 Dim Sum As Long = 0 Do While I <= 5 Sum += I I = I + 2 Loop
- 看程序，写结果 main() { int i,sum=0; i = 1; while (i < 100) { sum = sum + i; i++; } printf("%d",sum); }
- 智慧职教: 看程序，写结果main() { int i,sum=0; i = 1; do { sum = sum +2; i++; } while (i<100); printf("%d",sum); }
- 以下四个选项中和下面代码功能相同的是（ ）。（选择一项） int i = 1; int sum = 0; while (i <= 100) { if (i % 2 == 0) sum = sum + i; i++; } A: for (int x =1; x<=100;x++){ sum=sum+x;} B: for (int x =0; x<=100;x+=2){ sum=sum+x;} C: for (int x =1; x<=100;x+=2){ sum=sum+x;} D: 上述全对

下列for语句表示正确的是( ) A: for（Sum=0; i=<10; i++） B: for（Sum=0; i=1,i++) C: for（Sum=0, i=1, i++） D: for（Sum=0, i=1; i++）

以下四个选项中和下面代码功能相同的是。 int i = 1; int sum = 0; while (i <= 100) { if (i % 2 == 0) sum = sum + i; i++; }

中国大学MOOC: 如下代码片段的输出是什么？ int i = 1; int sum = 0; do { if (i % 7 == 0) sum = sum + i; i++; } while (sum < 100); printf(%d, sum);

4．编程计算1＋3＋5…＋99的值main(){ int i, sum = 0;i=1;while ( ) { sum = sum + i; ; } printf("sum=%d\n", sum);}

以下程序的运行结果是（）。main(){ int i=1,sum=0; while(i<;10) sum=sum+1;i++; printf("i=%d,sum=%d",i,sum);} A: 程序死循环 B: A:i=10,sum=9 C: B:i=9,sum=9 D: C:i=2,sum=1
