DESCRIPTION	: To print bits of signed and unsigned types for given number and check for 2’s complement
OUTPUT		: ./a.out
		ENTER THE NUMBER: 56
		+56 => 00000000000000000000000000111000
		-56 => 11111111111111111111111111001000
		DO YOU WISH TO CONTINUE(y/Y):y
		ENTER THE NUMBER: -8 
		-8 => 11111111111111111111111111111000
		+8 => 00000000000000000000000000001000
		DO YOU WISH TO CONTINUE(y/Y):n
