当数组大于8时打印数组元素的问题

Question

//read the elements of the array
cout<<"Enter all the elements of the array"<<endl;
for(j=0;j<size;j++)
  cin>>arr[j];

//populate the elements of the array
cout<<endl<<"Entered elements are as follows"<<endl;
for(j=0;j<size;j++)
 cout<<arr[j]<<"  ";

代码是用gcc编译的。 当我在ubuntu 14.04中运行代码并输入大于8的数组时，我没有得到任何输出。
