用VB编写计算器计算a b c

PrivateSubCommand1_Click()DimsumAsDoubleDimiAsLongDimnAsDoublen=((1/(10^-5))+1)/2'正好等于10^-5时候n的值

如果要判断句子中的英文单词是否正确,那就很麻烦的.如果不要判断单词的正确性,仅仅假设句子中.单词以空格分隔,那么就比较容易实现了.思路:1．计算句子的长度,字符数L2．ZFS----存放英文单词所用到

PrivateSubCommand1_Click()Dima,xAsSinglea=Val(Text1.Text)Ifa再问：x=x+a*0.2+3000*0.2怎么都乘0.2呀？

PrivateSubCommand1_click()DimnAsIntegern=100Printf(n)EndSubFunctionf(n)Fori=1Tonf=f+1/iNextiEndFunct

阶乘n!=n*(n-1)(n-2)(n-2)···3*2*1

新建工程,添加command1控件.vb6.0+xp调试成功代码如下：DimnAsIntegerPrivateSubCommand1_Click()m=InputBox("请输入底数m")n=Inpu

DimbAsLongb=Val(Text1.Text)SelectCasebCaseIs>100000Text1.Text=(b-100000)*0.45+29250Case80000To100000

将六个圆命名为“Oval1”直到“Oval6”在窗体上放6个timer控件.写入如下代码：Private Sub Form_load()'必要的初始化操作Timer1.in

#include#includeusingnamespacestd;classComplex{private:doublem_real;doublem_complex;public://各个函数的定义

你试试把d=a+c改为,d=Val(a)+Val(c)应该没问题了

用while的,其它的dowhile的基本相同PrivateSubCommand1_Click()DimnAsIntegern=InputBox("请输入")f=1i=2s=0Wh

什么意思?

那个是编程解决的下面是matlab程序function[C,R2]=linefit(xin,yin)iflength(yin)~=length(xin),error('xandyarenotcompa

#includevoidmain(){inta,b,d;charc;printf("请输入一种运算符：\n");scanf("%c",&c);printf("请输入两个数：\n");scanf("%d
