[编程入门]数字的处理与判断-题解（C++代码）

解题思路:

注意事项:

参考代码:

#include<iostream>

using namespace std;

int main()

{

int a,b,count=0,t;

cin>>a;

t=a;

for(b=0;b<=t*10;b++){

t=t/10;

count++;

}

cout<<count<<endl;

t=a;

if(count==5){

cout<<a/10000%10<<" "  <<a/1000%10<< " " <<a/100%10  <<" "<<a/10%10 <<" " <<a%10 <<" " <<endl; 

cout<<a%10<<a/10%10<<a/100%10<<a/1000%10<<a/10000%10;

}

if(count==4)

{   cout<<a/1000%10 <<" " <<a/100%10<<" "  <<a/10%10 <<" " <<a%10 <<" " <<endl;

cout<<a%10<<a/10%10<<a/100%10<<a/1000%10;

}

if(count==3){

cout<<a/100%10<< " "  <<a/10%10 <<" " <<a%10<<" "  <<endl;

cout<<a%10<<a/10%10<<a/100%10;

}

if(count==2) {

cout<<a/10%10<<" "  <<a%10 <<" " <<endl;

cout<<a%10<<a/10%10;

}

if(count==1){

cout<<a%10 <<" " <<endl;

cout<<a%10;

}

 }
