Answer 1

#include<iostream>
using namespace std;
int main()
{
    int n,temp,i;
    cout<<"Enter the number of elements in the array : ";
    cin>>n;
    int arr[n];
    cout<<"Enter the elements in the array : ";
    for(i=0;i<n;i++)
    {
        cin>>arr[i];
    }
    temp=arr[0];
    for(i=0;i<n;i++)
    {
        arr[i]=arr[i+1];
        if((i+1)>(n-1))
        {
            arr[i]=temp;
        }
    }
    cout<<"Elements of array shifted by one to the left : \n";
    for(i=0;i<n;i++)
    {
        cout<<arr[i]<<" ";
    }
}
