”C語言”一問

#include<stdio.h>
#include<stdlib.h>
main()
{
int i,n;
float sum=0;
printf("please enter a positive integer number : ");
scanf("%d",&n);
if(n!=0)
{
printf("1");
for(i=2;i<=n;i++)
{
sum+=(float)(1.00/i);
printf("+(1/%d)",i);
}
printf("=%f\n",sum+1);
system("PAUSE");
return 0;
}
else
printf("math error\n");
system("PAUSE");
}

This is the slowest diverging series that I know of. You can use a loop to do this within a few lines.

Champion大真愛說笑...

這題很多人問過了吧...
稍微找一下就有了...

我也好想知道這題要怎麼寫....
