Error detection and correction: cyclic redundancy check
consider the cyclic redundancy check (crc) algorithm discussed in section 5.2.3 of the text. suppose that the 4-bit generator (g) is 1001, that the data payload (d) is 1000 and that r=3.
 what are the crc bits (r) associated with the data payload of d = 1000, given that r=3?

[hint: recall from the text that in calculating the crc bits, all crc calculations are done in modulo-2 arithmetic without carries in addition or borrows in subtraction. this means that addition and subtraction are identical and both equal to the bitwise exclusive-or (xor) of the operands. if you'd like to review modulo-2 binary arithmetic, here is a nice site that provides a modulo-2 binary arithmetic calculator, and provides explanations of the calculations.]

This program should be a short piece of code that prints all of the positive integers from 1 to 100 as described more fully below. the program may contain multiple methods, and if using an oo language, should be contained within a single class or object. the program should be designed so that it begins execution when invoked through whichever mechanism is most common for the implementation language. â–ş print out all positive integers from 1 to 100, inclusive and in order. â–ş print messages to standard output, matching the sample output below. â–ş in the output, state whether the each integer is 'odd' or 'even' in the output. â–ş if the number is divisible by three, instead of stating that the number is odd or even, state that the number is 'divisible by three'. â–ş if the number is divisible by both two and three, instead of saying that the number is odd, even or divisible by three; state that the number is 'divisible by two and three'. â–ş design the logic of the loop to be as efficient as possible, using the minimal number of operations to perform the required logic. sample output the number '1' is odd. the number '2' is even. the number '3' is divisible by three. the number '6' is divisible by two and three.
