One & Two Dimensional Array in c++

// Program to illustrate one dimensional array
#include<iostream.h>
#include<conio.h>
#include<iomanip.h>
class onedarray
{
 public:
int a[33],i,n;
 public:
void getdata();
void putdata();
};

void onedarray::getdata()
{
 cout<<"Enter the size"<<endl;
 cin>>n;
 for(i=0;i<n;i++)
  {
  cout<<"Element a["<<i<<"] :"<<ends;
  cin>>a[i];
  }
}

void onedarray::putdata()
{
   /* for(i=0;i<n;i++)
     {
      cout<<a[i]<<" ";
     }*/ Comment is to display with out Address Array Data Location 
 
 for(i=0;i<n;i++)
 {
  cout<<"\nAddress:"<<&a[i]<<setw(15)<<"Array:"<<"a["<<i<<"]"<<setw(15)<<"Data:"<<a[i]<<setw(15)<<"Location:"<<i+1;
  cout<<"\n";
 }
}

void main()
{
 onedarray od;
 clrscr();
 od.getdata();
 od.putdata();
 getch();
}

Output:
