CSC $206$ Secure Systems Programming

Please finish the following tasks and put the snapshots inside one pdf document

You can use Microsoft Word first, and then export the document to a pdf

The numbers mentioned in task $1$ and task $2$ are all integer numbers, and their size are all $16$ bits. This means even for integer $1,$ you have to write the binary as $0000000000000001.$

Task $1(20$ points$)$

Use two's complement to represent the following integer number, show your steps of $1)$ absolute value, $2)$ complement, and $3)$ add one.

$-30$

$-189$

Task $2(30$ points$)$

Use two's complement to represent the numbers in the following expressions, and do the arithmetic addition calculation.

$23+(-29)$

$(-31)+6$

Task $3(20$ points$)$

Run all $4$ programs provided in "Lab.pdf$",$ and put your execution result in the submission.

Task $4(30$ points$)$

For the program $1$ in "Lab.pdf$",$ explain how to modify the program line $4$ that the number of iterations before integer overflow occurs becomes $2.$

Hints:

You only need to modify the line $4.$

Try to modify the line $4$ or line $5$ to see the output of each iteration of the for loop, and understand how the integer overflow occurs.

Check the maximum integer number for $32-$bit length storage.
