任意给定一个M进制的数x ，请实现如下要求

#include <iostream.h>
const int N=50;

void fun()
{
void circle();
int A[N];
for (int i=0;i<N;i++)
{
A[i++]=-1;//initial a array
}
int number;
int base;
cout<<"input a number:";
cin>>number;
cout<<endl;
cout<<"convert into ? ：";
cin>>base;
i=0;
while(1)
{
A[i++]=number%base;
number=number/base;
if (number<1)
break;
}
for(int j=i-1;j>=0;j--)
cout<<A[j];
cout<<endl;

char ch;
cout<<"input y to continue ,input n to exit!"<<endl;
cin>>ch;
if (ch=='y')
{
circle();
}
else
{
cout<<"http://hi.baidu.com/smilingsk
