c语言输入一个三位数,输出个位,十位,百位

intmain(){\x09intnum=456;\x09intg,s,b;\x09g=num%10;//个位\x09s=num%100/10;//十位\x09b=num/100;//百位\x09pr

给你个思路,先把输入的数字赋给a；设置一个数组b[10]；整数i；i=0；do{b[i]=a%10；a=a/10；i++；}whlie（a>0）这样的话,如果输入412；数组b的b[0]=2、b[1]

1#include"stdio.h"main(){intn,i;scanf("%d",&n);printf("%d",n/100+n%100/10+n%10);system("PAUSE");}2#i

#includeintmain(void){inta;intge,shi,bai;scanf("%d",&a);ge=a%10;shi=a/10%10;bai=a/100;printf("%d\n",

#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);

#includeintmain(){intn;scanf("%d",&n);do{printf("%d",n%10);}while(n/=10);printf("\n");return0;}

#includemain(){intn,i,j;scanf("%d",&n);n=2*n-1;for(i=1;i2*i){for(j=1;j

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. 

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

#include#includeintmain(){inti,num,n,ans,tt;while(scanf("%d",&num)!=EOF){ans=0;n=3;//如果要求N位数反转,把n改了就

#includevoidmain(){intn,m,a,b,c;scanf("%d",&n);a=n/100;b=(n/10)%10;c=n%10;m=c*100+b*10+a;printf("输出:

#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/

#include <stdio.h>int main(void){    int num, i, 

只是三位数的话,下面的代码就可以了!#includeintmain(){intn;inta,b,c;scanf("%d",&n);a=n%10;b=n/10%10;c=n/100;printf("%d

#includevoidmain(){inta;intb,c,d;//各个位数上的数字printf("请输入一个三位数:");scanf("%d",&a);b=a/100;//百位c=(a-b*100

#includeintmain(){inta[3];inti;for(i=0;i｛scanf("%.1d",&a[i]);｝printf("%d\n",a[0]+a[1]+a[2]);return0;

#includeintmain(){\x05intn;//\x05printf("请输入一个十位数:");\x05scanf("%d",&n);\x05printf("%d",n%10+n/10);}

#includemain(){inti,j,N,t,k=0;intscore[100];printf("请输入整数的个数N：\n");scanf("%d",&N);printf("请输入N个整数：\n

#includeintmain(){floatF,c;while(1){printf("请输入华氏温度：");scanf("%f",&F);c=5*(F-32)/9;printf("摄氏温度为：%0.

inti,a,n;int*pl=NULL;printf("inputn:");scanf("%d",&n);if(n>0){pl=(int*)malloc(n*sizeof(int));}for(i=
