Question

就是数据库啊,可以编程的,我们在上这课..太郁闷了..不会写..

Answer 1

你确认ACCESS可以编程吗？

//vc 6.0
#include <stdio.h>
void main()
{
int i=0;
float fSum=0;
for(i=1;i<=100;i++)
{
fSum+=(1.0/i);
}
printf("1+1/2+1/3+...+1/100=%f\r\n",fSum);
}

Answer 2

'''vb6.0
''-------------
Private Sub Command1_Click()

Dim i, j, k, p As Integer

j = 100

For i = 1 To j

If j Mod 2 = 0 Then
p = 1
Else
p = -1
End If

k = k + p * (1 / i)
Next i

Print k

Answer 3

public class Calculate {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
String opr = "+";

int n = 100;
double sum = 0;

for( float i = 1; i <= n; i++ ){
if( opr.equals("+")){
sum += 1 / i;
opr = "-";
}else{
sum -= 1 / i;
opr = "+";
}
}
System.out.println(sum);
}

}
