java 提示手动输入一个四位数: ge 0 shi0 bai0 qian1

#includeusingnamespacestd;voidmain(){inta[4];cout再问：还是有好几个错误再答：#includeusingnamespacestd;voidmain(

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

#includevoidmain(){inta[9][9],i,j,n;scanf("%d",&n);for(i=0;i

intm,n;scanf("%d",&m);n=(m/1000)*(m/1000)+(m/100%10)*(m/100%10)+(m/10%10)*(m/10%10)+(m%10)*(m%10);pr

#includeintmain(){intn,m;scanf("%d",&n);m=0;while(n>0){m=m*10+n%10;n/=10;}printf("%d\n",m);return0;}

程序试过正确(每位数都只能是0-9的),可复制：#include<stdio.h>main(){int a,b,c,d,t;printf("请输入一个四位数:\n&qu

importjava.util.Scanner;publicclassEncpryt{publicEncpryt(){Scannerscan=newScanner(System.in);System.

用字符数组存储这N个数再用ASCII码将字符类型的数字转换成整数数字再加起来即可；vara:array[1..10000]ofchar;i,s,n:longint;beginfori:=1to4dor

#include<stdio.h>int main(){int n,s=0;scanf("%d",&n);while(n){s=

intnum=4568;intshiwei=0,baiwei=0,qianwei=0,gewei=0;qianwei=num/1000;baiwei=(num%1000)/100;shiwei=(nu

数字操作：varn,s:integer;beginreadln(n);s:=0;whilen>0dobegins:=s+nmod10;n:=ndiv10;end;writeln(s);end.字符串操

#include#includeusingnamespacestd;voidmain(){chars[4];intn,k;cin>>s;sort(s,s+4);n=(s[0]-'0')*10

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

作为字符串形式读入比用整形读入好处理,而且数的位数不受限制（整型有数值超界问题）#includevoidmain(){chars[80];//最长80位数字inti,L;printf("pleasei
