十->二进制转换 （C语言代码）

#include <stdio.h>
#include <math.h>
int main()
{
     int m,n;
     int a[10000];

     while(scanf("%d",&n)!=EOF)
     {
              m=0;

              if(n>=0)
              {
                          if(n==0||n==1)printf("%11d-->%d\n",n,n);
                          else
                          {
                                printf("%11d-->",n);
                                while(n!=1)
                                {
                                                 a[m++]=n%2;
                                                 n/=2;
                                 }
                                 a[m]=1;
                                 for(;m>=0;m--)
                                      printf("%d",a[m]);
                                 printf("\n");
                           }
               }
               else
               {
                     printf("%11d-->",n);
                     while(n!=-1)
                     {
                                       a[m++]=abs(n%2);

                          printf("%d",a[m]);
