popBack and popFront

I could use some help. I am writting two functions, one is popBack and
one is popFront.

popFront needs to remove a data element from the front of my data
structure.
popFront (T& n)
{

}
popBack needs to remove a data element from the rear of my data
structure
popBack (T& n)
{

}

I have two functions ****ftRight and ****ftLeft that will move the
elements in the array right or left.

void ****ftRight()
		{
			//decrement this iteration
			for (int i = size; i >= 0; i--)
			{
				data[i] = data[i - 1];
			}
			size++;
		}
		void ****ftLeft ()
		{
			for (int i = 0; i < size; i++)
			{
				data[i] = data[i + 1];
			}
			size--;
		}
