     SIMILARITIES:
          > Both array name and pointer variable store the address of another variables.
	  > In case of array, it stores the address of its first elemenet(at index 0). 

     DIFFERENCES:
          > Using array name, whole array can be accessed but using pointer variable only one element can be accessed.
          > sizeof() operator returns size of array in case of array name whereas size of int in case of pointer variable.
