C语言输入一个数字,要求逆序输出,比如输入1234 输出4321

这是我写的程序.希望对您有用.1.#includevoidmain(){intx,y,z,a,b,c;printf("输入一个三位数x\n");scanf("%d",&x);a=x/100;y=x-1

#includelongf(longintx){inta[100];inti;for(i=1;;i++){a[i]=x%10;x=x/10;if(x==0)break;}return(i);}void

#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(){inti,j,a,b;scanf("%d\n",i);printf("pleaseinputnumber\n");scanf("%d\t",a);b=a;for(j

#include"stdio.h"//voidmain(void){inta,b,c;printf("请输入两个十进制整数!\na=");scanf("%d",&a);printf("b=")

你写的实在是太繁琐了.这个是不可取的.你需要的这两个功能其实是可以一起实现的,虽然一楼说的很对,当我觉得应该不是你需要的那一种方案.#includemain(){inti=0,k;inta[10;pr

main(){intx;scanf("%d",&x);x=(x%10)*100+(x/10%10)*10+(x/100)printf("%d\n",x);}

#includeintmain(void){longintx;inty,i=1;printf("请输入一个不超过100000的整数:");//99999||x

#includeintmain()#definen5{inta[n],m,b[n+1],temp,k,i;printf("n=%d\ntheorigalnumber:",n);for(i=0;i

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

/*从键盘上输入一个任意位数的正整数,判断它是几位数,并逆序输出该数*/#include"stdio.h"intmain(){intnum,temp,i=0;printf("请输入一个数字\n");s

x%10=a1,x/10%10=a2,x/100=a3,a=a1*100+a2*10+a3再答：判断是几位:if(a>100)3if(a>1000)4if(a>10000)5再问：再问：能帮我看一下错

可以是可以,不过太麻烦了,见下面的代码#includeintmain(){inta,b[5],s=0;scanf("%d",&a);while(a){b[s++]=a%10;a/=10;}printf

#include"stdio.h"#include"conio.h"#defineQ100voiddx(chars[Q])/*自定义函数,功能实现字符串倒叙*/{inti,j;chartemp;for

#include"stdio.h"voidmain(){intx,a,b,c,d,e,n,j;printf("请输入一个不多于5位的正整数\n");scanf("%d",&x);a=x/10000;b

#includevoidmain(){intnum;printf("Enteranumber!(9

#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.

#include#defineMAXN20intmain(){intn,t,k=0;intia[MAXN];printf("请输入一个整数:");scanf("%d",&n);while(t=n%10

#includevoidinput(inta[],intn)//输入{inti;printf("请输入%d个数,用空格隔开\n",n);for(i=0;i

#include#defineNUM20voidmain(){longn;intdata[NUM]={0},len=0;scanf("%d",&n);do{data[len++]=n%10;n/=10
