Problem Description

Give you a number on base ten,you should output it on base two.(0 < n < 1000)

 

Input

For each case there is a postive number n on base ten, end of file.

 

Output

For each case output a number on base two.

 

Sample Input

1
2
3

 

Sample Output

1
10
11
题目大意：10进制转二进制
思路：%2去余数存数组倒着输出
代码：#include<iostream>
#include<string.h>
using namespace std;
int main()
{

 int n,a[32];

   while( cin>>n)
   { int i=0;
   memset(a,0,sizeof(a));
   while (n>0)
    {
        a[i]=n%2;
        i=i+1;
        n=n/2;
    }
     i--;
    for(;i>=0;i--)
    cout<<a[i];
 cout<<endl;
 }

return 0;
}
