第1题：
如果一个正整数从高位到低位上的数字依次递减，则称其为降序数(如：9632是降序数，而8516则不是降序数)。现编写如下程序，判断输入的正整数是否为降序数。 Private Sub Command1 Click（ ） Dim n As Long Dim flag As Boolean n=InputBox("输入一个正整数") S=Trim(Str(n)) For i=2 To Len(s) If Mid(s，i-1，1)<Mid(S，i，1)Then Exit For Next i If i=Len(S)Then flag=True Else flag=False If flag Then Print n；"是降序数" Else Print n；"不是降序数" End If End Sub 运行以上程序，发现有错误，需要对给flag变量赋值的If语句进行修改。以下正确的修改是（ ）。
A.If i=Len(s)+1 Then flag=False Else flag=True
B.If i=Len(s)+1 Then flag=True Else flag=False
C.If i=Len(s)-1 Then flag=False Else flag=True
D.If i=Len(s)-1 Then flag=True Else flag=False

第7题：
请补充main函数，该函数的功能是：把1～100间的所有素数保存在数组aa中，然后输出这些素数并计算它们的和。
注意：部分源程序给出如下。
请勿改动主函数main和其他函数中的任何内容，仅在 main函数的横线上填入所编写的若干表达式或语句。
试题程序：
include＜stdio.h＞
main()
{
int n, i, j, k, flag, sum;
int aa [50];
sum=O;
k=O;
clrscr ();
for (i=2; i＜100; i++)
{
【 】;
for (j=2; j＜i＆＆flag; j++)
if (i%j==O)
{
【 】;
}
if (flag)
{
sum+=i;
【 】;
}
}
printf("\n*** prime number ***\n");
for (i=0; i＜k; i++)
{
if (i%10==0)
printf ("\n");
printf ("%4d", aa [i]);
}
printf ("\nsum=%d", sum);
}
