Function isprime(n) As Integer

isprime = 0

For i = 3 To Sqr(n + 1) Step 2

If n Mod i = 0 Then

Exit Function

End If

Next i

isprime = 1

End Function

Private Sub Command1_Click()

n = 0

Label1.Caption = ""

For i = 3 To 100 Step 2

If isprime(i) = 1 Then

Print i;

n = n + 1

If n Mod 10 = 0 Then Print

Label1.Caption = Label1.Caption & i & " "

End If

Next i

End Sub

=================

//求完数

#include<stdio.h>

int sum1(int n)

{int s=1,i;

if(n==1)return 0;

for(i=2;i<=n/2;i++)

if(n%i==0)s+=i;

return s;

}

int main()

{ int i,j,n;

scanf("%d",&n);

for(i=1;i<=n;i++)

if(sum1(i)==i)

{printf("%d=1",i);

for(j=2;j<=i/2;j++)

if(i%j==0)printf("+%d",j);

printf("\n");

}

return 0;

}
