Suppose I define some structure type ( studentInfo), then I declare an instance of it and I decide to also create a pointer to t

he instance like so:
typedef struct{

int age;
char idNum[9];
}
studentInfo;

...Code continues...

struct studentInfo mainInfo, *pMain;
pMain = &mainInfo;

Which of the following options is functionally equivalent to:

a. (p*Main).age = 20;
b. *pMain.age = 20;
c. pMain.age = 20;
d. *(pMain.age) = 20;

Your boss asks you to transmit a small file that includes sensitive personnel data to a server on the network. The server is run
mel-nik [20]

Answer:

a. Telnet transmissions are not encrypted.

Explanation:

Indeed, since <em>Telnet transmissions are not encrypted,</em> all the information sent, and even the characters typed in the telnet console are sent in clear text.

This is a security issue, since any other device in the same network will receive a copy of the information (packets) sent. For default, all the devices, except for the server expecting to receive the information, will discard the packets. However it is easy to actively <em>listen </em>and keep those packets, wich will contain the information in plain text and human readable.

A method to accept the number of drawers in the desk as input from the key board. This method returns the number of drawers to t
Julli [10]

Answer:

Following code takes the information about the wood from the user, do the process of calculating the value according to there type and numbers, then add the surcharge to it while giving the answer to the user.

For differentiating the type of woof i used the if then else statement while i used switch case statement for assigning the appropriate value according to the types of the wood will be processing in the program.

The code is given below:

Explanation:

Code:

namespace std;\\ any name instead of std.

{

   class Program

   { \\ starting the main program

       static void Main(string[ ] args)

       {

           int numberOfDrawers = 0;

           string deskWoodType = "o";

           double cost = 0;

           drawersMeth(numberOfDrawers);

           woodTypeMeth(deskWoodType);

           CalculateCostMeth(numberOfDrawers, cost, deskWoodType);

           OutPutCostMeth(deskWoodType , cost, numberOfDrawers);

       }//end main

       private static void drawersMeth(int numberOfDrawers)

       {

           int numOfDrawers;

           Console.WriteLine("Enter the number of desk drawers");

           numOfDrawers = Convert.ToInt16(Console.ReadLine());

           numberOfDrawers = numOfDrawers;

       }//end drawersMeth

       private static string woodTypeMeth(string deskWoodType)

       {

           Console.WriteLine("Enter the desk wood type. (eg. type mahogany, oak, or pine)");

           deskWoodType = Convert.ToString(Console.ReadLine());

           switch (deskWoodType)

           {

               case "mahogany":

                   {

                       deskWoodType = "m";

                       break;

                       break;

                   }

           }

           return deskWoodType;

       }// end woodTypeMeth

       private static int CalculateCostMeth(string deskWoodType, int numberOfDrawers, int cost)

       {

           int pine = 100;

           int oak = 140;

           int other = 180;

           int surchage = 30;

           if (deskWoodType == "p")

               cost = surchage + (numberOfDrawers *pine );

           else if (deskWoodType == "o")

               cost = surchage + (numberOfDrawers *oak );

           else

               cost = surchage + (numberOfDrawers *other );

           return cost;

       }// end CalculateCostMeth

       private static void OutPutCostMeth(int numberOfDrawers, string deskWoodType, int cost)

       {

           double totalCost = cost;

           Console.WriteLine("The number of drawers is {0}", numberOfDrawers);

           Console.WriteLine("The wood finish you have selected is ", deskWoodType);

           Console.WriteLine("The total cost is {0}", totalCost);

       }//end outputCost

Why we need each section of prologprogram?
evablogger [386]

Answer:
