def func(): global sum sum=0 print(sum) for i in range(5): sum+=1 print(sum) func() print(sum)

阅读下面代码，判断正误sum = 0i = 1while i<;10: sum = sum + i i = i +1print "sum is ", sum

将下面的for循环转换为while循环，补全代码。 long sum=0; for(inti=0;i<=100;i++) sum=sum+i; System.out.println("sum="+sum); 改写成： long sum=0; ① ； while( ② ){ sum=sum+i; ③ ; } System.out.println("sum="+sum);

System.out.println("sum:"+sum);为输出sum的值。

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 &lt;&gt; 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 &lt;&gt; 0 Then sum = sum + i Next

如果N=2，Sum(N)是一个函数，且Sum(1)=5，那么语句：Set Sum=Sum(N-1) +N将把值6赋给Sum。If N = 2, Sum (N) is a function and Sum (1) = 5, then the statement:Set Sum = Sum (N-1) +NThe value 6 will be assigned to Sum.

下面的代码段有什么错误?for(i = 0; i <; 10; i++) {int sum;sum = sum + i;}System.out.println("Sum is: " + sum);

在excel中,函数sum(A1:A4)等于() A: sum(A1*A4) B: sum(A1+A4) C: sum(A1A4) D: sum(A1+A2+A3+A4)

计算2+4+6+…+100的值。 int i,sum=0; for(_______________) sum=sum+i; printf(“sum=%d”,sum);

下列程序段的运行结果是　　　。 #defineADD(x)x+x......sum=ADD(3+2)*2;printf(“sum=%d”,sum); A: sum=20 B: sum=12 C: sum=15 D: sum=30
