Step 1: Determine the number of subnets in Network Topology A. 1) How many subnets are there? Remember: • All LANs connected to Routers are to be counted as a subnet • Router1 (R1) to Router2 (R2) is to be counted as a subnet. • Router2 (R2) to Router3 (R3) is to be counted as a subnet. • Router1 (R1) to Router3 (R3) is to be counted as a subnet

Perform the following tasks: a. create a class named testclass that holds a single private integer field and a public constructor. the only statement in the constructor is one that displays the message “constructing”. write a main()function that instantiates one object of the testclass. save the file as testclass. cpp in the chapter 08 folder. run the program and observe the results. b. write another main()function that instantiates an array of 10 testclass objects. save the file as test class array. c . run this program and observe the results.

When creating a field in a table, you must set the to determine what type of data the field can store. field property data type field type data property

File i/o activity objective: the objective of this activity is to practice working with text files in c#. for this activity, you may do all code in the main class. instructions: create an app that will read integers from an input file name numbers. txt that will consist of one integer per record. example: 4 8 25 101 determine which numbers are even and which are odd. write the even numbers to a file named even. txt and the odd numbers to a file named odd. txt.
