以下JSP页面中的java表达式哪个语法正确?
A: 《%=sum+100%》
B: <%=sum+100%>
C: <%=sum+100>
D: <%sum+100%>
A: 《%=sum+100%》
B: <%=sum+100%>
C: <%=sum+100>
D: <%sum+100%>
举一反三
- 在报表中能够正确计算销售百分比的表达式为( ) A: [销售额]/Sum(“[销售额]”)*100 B: [销售额]/Sum[销售额]*100 C: =[销售额]/Sum(“[销售额]”)*100 D: =[销售额]/Sum([销售额])*100
- 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
- 计算2+4+6+…+100的值。 int i,sum=0; for(_______________) sum=sum+i; printf(“sum=%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
- $sum = 0; for($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_______
