How to shift elements of a single dimensional array by one position?

C program to shift elements of a single dimensional array in the left direction by one position. This C program is to shift the elements of a single dimensional array in the left direction by one position.For example, if an array a consists of elements a={1,2,3}, then on shifting these elements towards the left direction we would get a={2,3,1}.

How do you move elements in an array to the right?

We store the last element in the temp variable and then put it in the starting position i.e. a [0] and the remaining elements we shift it towards the right by one position by storing the element in the current position to the next position. Let us take elements for array a= {1,2,3}.
