Answer:

a KVM switch

Explanation:

KVM switch is devise used for handling or connecting different server at any time by using single mouse, monitor and keyboard. it is like an interface used to connect different server at any given time.

different type of KVM switch are

1) USB based KVm

2) Emulated USB type KVM

3) DDM USB type KVM

4) semi -DDM KVM

Find every number from 1 to n (inclusive) that is a palindrome which starts with the digit 3. Do not user a helper function.
Mkey [24]

Answer: Following code is in python

n=input()

num='1'

while int(num)<=int(n):    //loop from 1 to n

   flag=1   //if an unequal element will be found it will be 0

   l=len(num)

   if num[0]=='3':

       j=0

       k=l-1

       while j<k:    //loop till middle of number

           if num[j]==num[k]:

               j+=1     //from beginning

               k-=1    //from end

           else:

               flag=0

               break

       if flag==1:

           print(int(num))

   num=str(int(num)+1)    //number will be incremented as integer

INPUT :

1000

OUTPUT :

3

33

303

313

323

333

343

353

363

373

383

393

Explanation:

In the above code, a loop is executed till num is equal to n which is entered by the user. num is treated as a string so that to ease the process of checking first character is 3 or not. If it is 3 then another loop executes which checks if an element from starting is equal to the corresponding element from the end. If an element is not equal then the flag is changed and then we break out of the loop and prints the number if the flag isn't changed.

The major objective of this lab is to practice class and object-oriented programming (OOP), and separate files: 1. We will reuse

Answer:

Implementation of resistor.cpp

#include "resistor.h"

Ohms::Ohm()

{

// default constructor

voltage=0;

}

Ohms::Ohm( double x) // parameterised constructor

{

voltage = x; // voltage x set to the supply voltage in the private data field called voltage

}

Ohms:: setVoltage(double a)

{

voltage = a;// to set supply voltage in private data field called voltage

}

Ohms::setOneResistance( String s, double p)

{

cin>>p; //enter the resistance value

if(p<=0) // if resistance is less than or equals to 0

return false

else // if re

cin.getline(s);

}

Ohms::getVoltage()

{

return voltage; //return voltage of ckt

}

Ohms::getCurrent()

{

return current; //return current of ckt

}

Ohms:: getNode()

{

return resistors; //return resistors of ckt

}

Ohms::sumResist()

{

double tot_resist = accumulate(resistors.begin(),resistors.end(),0); //std::accumulate function for calculating sum //of vectors and following are the starting and ending points

return tot_resist;

}

Ohms::calcCurrent()

{

if(current <=0) // if current is less than or equal to 0

return false;

else   // if current is greater than 0

return true;

}

Ohms:: calcVoltageAcross()

{

if(voltage<=0) // if voltage is less than or equal to 0

return false;

else //if voltage greater than 0

return true;

}

Explanation:

in the case of main.cpp its simple just make a class object and remember to include resistors.cpp with it for which the second last picture describes the process precisely. (Hint: Use theunit test case functions in the main.cpp).

As you can see node is a structure consisting of member variables, followed by a class Ohms representing a DC circuit.

By looking at these pictures, it is needed to implement the main.cpp and resistor.cpp files. The user defined header file resistor.h already consists of all contents of Class Ohm, struct node. You don't need to modify it in anyway in such case.
