This code fills up an array from command line then proceeds to apply unary negation on the decimal and binary values for each element of the array. in the negative binary however, I am trying to only print the first 8 bits for any value in the list, but I could not achieve so using the & operator. Any Suggestions? 

also (int) in the 16th line has been unavoidable for me to make this c
+ode work since I wanted to work with numbers
