如何用VF编写一个程序计算S=1 2 ..... 100

直接调用log（）函数计算就可以了.

s=0fori=1to1000step2s=s+iifs>1000?s-iexitendifendforreturn

#include#includemain(){inta,n,i,sum=0,sum1,sum2,sum3;//sum为最后结果printf("inputthenumbera:");scanf("%d"

s=0k=1whilei

#includeintmain(){intn;scanf("%d",&n);do{printf("%d",n%10);}while(n/=10);printf("\n");return0;}

简单,程序如下:cleam=0n=0sm=1sn=1s=0@4,4say'inputm'getmread@5,4say'inputn'getnreadfori=1tomsm=sm*iendforfor

先设置界面如下加法按钮代码voidCMy03Dlg::OnBnClickedButton1(){//TODO：在此添加控件通知处理程序代码UpdateData(TRUE);m_Nub3=m_Nub1+

迭加,把前一次算得的和作为后一次运算的一个加数,如S=0+1算得S=1,下一步S=S+2=1+2=3再问：FORi=100TO1step-2麻烦解释一下嘛再答：S初值应该是0吧，(1)S=100+0=
