write a simple project to practice pointer only use pointer in c++

• Use T as the array type (typedef)
• Pass int size to all functions
• Do not use the Null Character to detect the end of array. (this, after all, could be an array of ints)
• Use a find function that returns a pointer to the location of the first occurrence of a key. (or a nullptr if not found)
• Use a shift_left function that shifts the elements of the array left at a given position
