Question

编程求1－99的平方和并输出结果。(328350)
Private Sub Form_Click()
Dim i As Integer, s As Single
For i = 1 To 99

  Next i
  FontSize = 12
  FontBold = True
  Print s

End Sub

编程求1到5000之间的能被5整除的前若干个奇数之和，当和大于500时,终止求和，并输出该和
Private Sub Form_Click()
Dim i As Integer, s As Long
FontSize = 14
FontBold = True

If i Mod 2 <> 0 Then s = s + i
If s > 500 Then Exit For
Next i
Print s
End Sub

Answer 1

#include <stdio.h>
int main()
{
    int sum = 0;
    for (int i = 1; i <= 99; i++)
        sum += i * i;
    printf("%d\n", sum);
    return 0;
}
