L1-007 念数字 格式错误

显示格式错误，这是为什么，求解

#include
using namespace std;
int main()
{
string arr[11]={"ling","yi","er","san","si","wu","liu","qi","ba","jiu","fu"};
int n;
cin>>n;
string zuihou="";
if(n==0)
{
zuihou=arr[0];
}
else if(n>0)
{
while(n>0)
{
int i=n%10;
zuihou=arr[i]+" "+zuihou;
n=n/10;
}
}
else
{
n=fabs(n);
while(n>0)
{
int i=n%10;
zuihou=arr[i]+" "+zuihou;
n=n/10;
}
zuihou=arr[10]+" "+zuihou;
}
cout<
return 0;
}

好像没啥问题把
