vb 作业编写程序计算100-300之间除5余1并且除7余2的所有数的和,并输出

语句自己找给思路.第一种：暴力运算1.申请2个变量jsum,osum分别放奇数和、偶数和.赋初值0.2.做个循环从1到100,变量用i2.1判断i是否为奇数,是的话jsum=jsum+i,否则osum

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

关于你说的变量的声明（定义）问题,你需要掌握变量的作用域的概念：我给你一个例子,看看能否了解.

dimxasinteger,dimsumasintegerforx=1to100ifxmod3=0thensum=sum+xendifnextxprintsum

拜托,这么多输入你就用列表啦,用那么多textbox,你不累我看得都累.还有,你要求的是什么尽量用数学的方式表达出来,有图更好至于你的a5d6的问题,是因为你的是字符串运算而不是数值运算,转换一下类型

;MOVAX,AANDAX,B;AX=aANDbMOVBX,AXORBX,B;BX=aXORbADDAX,BXADDAX,BX;AX=2*(aXORb)+aANDbADDAX,A;AX=a+2*(aX

PrivateSubCommand1_Click()Dimsum,xx=0sum=0Fori=1To200x=x+2*(i-1)sum=sum+xNextPrintsum'结果为2666600EndS
