编写程序,计算下面n(n∈N*)个数的和 2,32...(n+1)n 用BASIC程序语言 写出算法

Dim i as integer,n as integer,sum as integer input "the num is :"n sum = 0 for i = 1 to n sum = sum + (i+1)/i next i print "the sum is:"sum 楼上是VBasic的写法,我这个应该是QBasic的写法,比较古老,不知道楼主要的是哪个版本,好久没写QB了,不知道有没语法错误.

#include <stdio.h>

 

void  main() 

{

    int i=1,j

double sum=0

scanf("%d",&j)

    while(i <=j )

{

        sum+=(i+1)/i

        i++

    }

  printf("sum=%f",sum)

}
