c语言编程:输入一个3位数整数n,要求正确分离出它的个位数g,十位数s和百位数b

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}

楼上是C++写的,这个是C语言版的#include#includeintmain(){intcount;int*arrayLenth;int**intArray;int*elem1,*elem2;in

你的程序中判断素数并加和的部分有问题在你的基础上修改如下PS:main不需要改动# include <stdio.h>int SumPrime(int&nbs

#includevoidmain(){intx,a,b,c;scanf("%d",&x);a=x/100;b=x/10%10;c=x%10;x=c*100+b*10+a;printf("%d",x);

int类型所能容纳的数字位数不能超过10.我写的这个程序稍微长了点,但不受int类型容量的限制,能够处理很长的整数输入（由buffer数组的大小决定）.这程序只处理纯整数输入.有疑问尽管问. 

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

inti=2123;intone,two,three,four;one=i%10;//各位two=(i/10)%10;//十位three=(i/100)%10;//百位four=(i/1000)%10

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

#includevoidmain(){inti,j,k,m;printf("inputdata:");scanf("%d",&m);/*输入一个3位数*/i=m/100;j=(m-100*i)/10;

程序经过我用多组数据验证无错误,#includeintdigui(intt,intsum)//递归函数{if(t

#include#includeintmain(void){intn,sum=0,count=0,s;printf("输入一个整数:");scanf("%d",&n);while(n){s

#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
