求输入整数各位数字之和在自定义函数中计算

c++版的#includeusingnamespacestd;intmain(){intnum;cout

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("%

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

#include<iostream>usingnamespacestd;intmain(){cout<<"请输入一个整数"<<endl;intnum;cin>

#includeintmain(){intx;inta[20];scanf("%d",&x);inti;for(i=0;x>=10;i++){a[i]=x%10;x=x/10;}

如果不用log函数,并假设输入的数indata是非负整数,则可以如下：intn,s;n=0;s=0;while(indata){n++;s+=indata%10;indata/=10;}位数在n中,和

#include#defineerror-1intatoi(charc)voidmain(){chara[20];printf("inputnumber:");scanf("%s",a);intsum

太简单了吧#includevoidmain(){intA,bai,shi,ge;printf("请输入一个三位整数A：");scanf("%d",&A);bai=A/100;shi=A%100/10;

#includeintf(intn){if(n==1)return1;elsereturnn*f(n-1);}intmain(){intn;printf("请输入n的值：");scanf("%d",&

#includeintn,m=0;intmain(){scanf("%d",&n);while(n){m+=n%10;n/=10;}printf("%d\n",m);return0;}再问：看不懂。能

#includeintmain(void){intn,s=0,i=0,a=0;printf("Inputaninteger:");scanf("%d",&n);while(n!=0){s+=(n%10

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

importjava.util.Scanner;publicclassgeweiqiuhe2_5{publicstaticvoidmain(String[]args){Scannersc=newSca

intdata=inputdata;if(data>99&&data

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："

#includevoidmain(){intn,sum=0,digit=0;scanf("%d",&n);while(n!=0){sum+=n%10;digit++;n/=10;}printf("每位

1.第一个空填in0.判断循环里面做了运算之后,剩下的这个in是不是已经为0了,否则的话,说明还有某位需要求和,累加

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
