Pointers are variables following all the normal naming convention of non - pointer variables.
Pointers store addresses while non-pointers store data values. Since memory addresses are effectively integral values, pointers contain integer values that represent memory locations of other variables. Just as an array of characters or an array of integers or an array of float, etc., may be declared, so must an array of pointers be declared.
