c#输入一个整数,计算它各位上数字的和.(注意:是任意位的整数)

一：#includevoidmain(){inta,i=0,sum=0;scanf("%d",&a);while(a){sum+=(a%10);//sum是个位数之和a/=10;i++;//i为位数}

#includeintGetNumber(intn)//用递归来实现很简单{intsum=0;if(n/10!=0){\x09sum+=GetNumber(n/10);}sum+=n%10;retur

intfun(longx){ints=0,j;while(x){j=x%10;s=s+j;x=x/10;}returns;}main(){longn;scanf("%ld",&n);printf("%

#includemain(){inti=0,s=0,n;scanf("%d",&n);while(n>0){s+=n%10;i++;n/=10;}printf("%d%d\n",s,i);}

#includeintfun(intn){ints=0;while(n){s+=n%10;n=n/10;}returns;}main(){intn;scanf("%d",&n);printf("%d\

usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;namespacetest{classPro

#includevoidmain(){inta;printf("请输入一个三位数：");scanf("%d",&a);printf("各位数上的乘积为：%d\n",(a/100)*(a%10)*(a/

varn,s:longint;beginread(n);s:=0;whilen0dobegins:=s+nmod10;n:=ndiv10;end;writeln(s);end.自创!

方法一：//用数学函数#include#includevoidmain(){inta;scanf("%d",&a);printf("%d\n",abs(a));}方法二：//判断#includevoi

#includeintmain(){intn,sum=0;printf("请输入一个整数：");scanf("%d",&n);while(n){sum=sum+n%10;n/=10;}printf("

#includeintmain(void){\x09intnum,i,j,k,sum;\x09printf("输入一个三位整数!\n");\x09scanf("%d",&num);\x09i=num%

如该数为m则其十位数为a=m/10整个位数为b=m/10取余

=SUMPRODUCT(--(MID(A1,ROW(INDIRECT("1:"&LEN(A1))),1)))

clearinput"输入整数N:"tonn=abs(n)ifn>0\x05sn=len(alltrim(str(n)))\x05?"此数是个"+alltrim(str(sn))+"位数.各位数是："

using System;namespace ConsoleApplication2{    class Program 

先看它一共有几位假设有54321位,该数字除以10000取模,就是第一位数字5,然后减去50000,得4321,继续

不明白楼主让用C语言,大家怎么都用C++ #include<stdio.h>void main(){ int num,temp,number=0,s

这个应该是用编程的吧,给你c++代码#includeusingstd::cout;usingstd::cin;usingstd::endl;intmain(){intnum=0;//需要输入的整数in

楼上说没错,while(X)是先进行X判断然后再执行{语句体},而do..while则是先执行do{语句体},再判断while(X),这样会导致do..while比while执行语句体的次数多一次再问
