Explanation of Solution
Given: The values of the variables, x = 2, y = 3, and z = 2, are assigned to the expression, x++ + y++.
 To find: The result of the expression, x++ + y++, if x = 2, y = 3, and z = 2.
Solution:
In the expression, x++ + y++, postfix operator is used which is a unary operator working on a single variable and it used to either decrement or increment the variable’s value.
But in this, the original value is returned first, and then it gets incremented or decremented by 1...

Explanation of Solution
Given: The values of the variables, x = 2, y = 3, and z = 2, are assigned to the expression, x++ + y++.
To find: The result of the expression, ++x - --z, if x = 2, y = 3, and z = 2.
Solution:
In the expression, ++x - --z, prefix operator is used which is a unary operator working on a single variable and it used to either decrement or increment the variable’s value.
But in this, the original value gets incremented or decremented first, and then the value gets returned...

To find: The result of the expression, --x + y++, if x = 2, y = 3, and z = 2.
Solution:
In the expression, --x + y++, prefix and postfix operators are used.
Postfix operator is a unary operator working on a single variable and it used to either decrement or increment the variable’s value. But in this, the original value is returned first, and then it gets incremented or decremented by 1.
Whereas the prefix operator is a unary operator working on a single variable and it used to either decrement or increment the variable’s value...

Explanation of Solution
Given: The values of the variables, x = 2, y = 3, and z = 2, are assigned to the expression, x + y-- - x + x++ - --y.
To find: The result of the expression, x + y-- - x + x++ - --y, if x = 2, y = 3, and z = 2 .
Solution:
In the expression, x + y-- - x + x++ - --y, prefix and postfix operators are used.

- No AI solutions pleasearrow_forwardCreate an original network topology consisting of at least seven routers and twelve links, assigning arbitrary positive weights to each link. Using this topology, apply Dijkstra's Link-State Algorithm to compute the shortest paths from a source router of your choice to all other routers in the network. Your topology must be entirely your own design and should not resemble any examples from the textbook, lecture slides, or other students' work. Al-generated topologies are not permitted. Create a PowerPoint presentation that follows the format and style of slides 11 to 23 from Lecture Slide Set 06 (LS06). You should copy those slides and make any necessary changes, additions, or deletions to reflect your own topology, shortest-path calculations, and update tables. Do not alter the original slide style, layout, or formatting.arrow_forwardCreate an original network topology consisting of at least seven routers and twelve links, assigning arbitrary positive weights to each link.

The host computers use private IP address space: 192.168.2/24. Each host is trying to establish 2 TCP connections to a remote webserver through the NAT router. The IP address of the webserver is: 130.12.11.9. Now do the following: 1 a. Assign IP addresses to the interfaces of the hosts and the router. For the router, assign arbitrary addresses. List these addresses. b. Now create a NAT translation table as taught in the class for all TCP connections. Assign arbitrary port numbers as required.arrow_forward1) Consider the following network. Host h6 10.3.0.6 Host h5 10.3.0.5 Host h1 10.1.0.1 OpenFlow controller m 2 3 4 Host h4 10.2.0.4 Host h2 10.1.0.2 Host h3 10.2.0.3 The desired forwarding behavior for the datagrams arriving at s2 is as follows: a) any datagrams arriving on input port 1 from hosts h5 or h6 that are destined to hosts h1 or h2 should be forwarded over output port 2; b) any datagrams arriving on input port 2 from hosts h1 or h2 that are destined to hosts h5 or h6 should be forwarded over output port 1; c) any arriving datagrams on input ports 1 or 2 and destined to hosts h3 or h4 should be delivered to the host specified; d) hosts h3 and h4 should be able to send datagrams to each other. Create a flow table for s2 that implement these forwarding behaviors. Your table should have 2 columns one for match and the other for actions, as taught in the class.arrow_forward
