Binary and hexadecimal values have the following pair equivalences.
















We convert from binary to hexadecimal selecting groups of 4 binary from the binary code, from the least significant bits(at the right) to the most significant bits(at the left). The conversion is an hexadecimal "string" from the last group you converted to the first. So:
(a) %100011100101



So

This is a little tricky. I would say reserve. It would help to know what programming language and class this is for because a lot of times when you create an array variable the memory is put onto the stack and you as the programmer do not reserve memory space. Now on the other hand, if you are programming in C and you want to create an array variable and put it on the heap then you would reserve memory space on the heap.
