Code:
#include<iostream.h>
#include<conio.h>
int x;
void main()
{
int arr[20],num;
cout<<"enter the number of digits:"<<endl;
cin>>num;
cout<<"enter the number:"<<endl;
for(int i=0;i<num;i++)
{
cin>>arr[i];
}
for(int j=0;j<num;j++)
{
for(int k=0;k<num;k++)
{
for(int l=0;l<num;l++)
{
cout<<endl;
cout<<arr[l];
}
x=arr[num-1];
for(int m=0;m<num-1;m++)
{
arr[m+1]=arr[m];
}
arr[j]=x;
}
}
getch();
}
