POINTER

BASE ADDRESS AND CONSTANT POINTER :- When an array (any data type ) is declared , the compiler allocate a base address and sufficient amount of storage to contain all the element of the array in contiguous location .The BASE ADDRESS is the location of the first element( index 0) of the array .The compiler also defines the array name as a CONSTANT POINTER to the first element .Example int num = {12 , 5 , 107 , 55 , 291 } -- here an int type array num is declared and "num" is the constant pointer that denotes the base address of &num[0].
