Answer:
Docking Station is the correct answer of the following question.
Explanation:
A docking station is a technology system that is able to communicate capacities touchscreens with the other machines with few or no work.
The docking station is a system connecting a machine to many devices.
- The docking station lets you attach to gadgets you have not been able to use in the future.
- Not always connected with machines are docking station items such as sloped-panel displays and interchangeable lens cameras.
Answer:
C code for half()
#include<stdio.h>
void half(float *pv);
int main()
{
float value=5.0; //value is initialized
printf ("Value before half: %4.1f\n", value); // Prints 5.0
half(&value); // the function call takes the address of the variable.
printf("Value after half: %4.1f\n", value); // Prints 2.5
}
void half(float *pv) //In function definition pointer pv will hold the address of variable passed.
{
*pv=*pv/2; //pointer value is accessed through * operator.
}
- This method is called call-by-reference method.
- Here when we call a function, we pass the address of the variable instead of passing the value of the variable.
- The address of “value” is passed from the “half” function within main(), then in called “half” function we store the address in float pointer ‘pv.’ Now inside the half(), we can manipulate the value pointed by pointer ‘pv’. That will reflect in the main().
- Inside half() we write *pv=*pv/2, which means the value of variable pointed by ‘pv’ will be the half of its value, so after returning from half function value of variable “value” inside main will be 2.5.

Answer:
// program in C++.
// headres
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// array
int temperatures[7];
// count variable
int count=0;
cout<<"Enter the temperature of all days:";
for(int a=0;a<7;a++)
{
// read temperature of 7 days
cin>>temperatures[a];
// find temperature is extreme or not
if(temperatures[a]<-10||temperatures[a]>25)
// count
count++;
}
// print count of extreme temperature
cout<<"number of days of extreme temperature:"<<count<<endl;
return 0;
}
Explanation:
Create an array of size 7 to store the temperature of all days of week.Read the temperature of each day.If the temperature is less than -10 or greater than 25 then increment the count.This will count the number of days of extreme temperature.Print the count.
Output:
Enter the temperature of all days:-20 12 18 30 32 -15 15
number of days of extreme temperature:4
Answer:
Begin the statement with the proper keyword to start the loop
Explanation:
Given
The code segment
Required
Fix the code
The first line of the code segment is meant to be a for loop, but it does follow the right syntax.
This is so because the for keyword is missing.
The first line should be corrected and replaced with:
for count in range(80):
Hence, option (b) is correct
Solution :
- Loopback plug --- confirm interface functionality
It is a connector that is used to diagnose the transmission problems.
- Protocol Analyzer --- Analyze network traffic
It is used to capture and analyze the signals as well as data traffic.
- Throughput tester - Measure link speed
- Time Domain Reflectometer (TDR) - Determining the location of cable fault
It is used in determining the characteristics of the electrical lines by observing the reflected waveforms
- Locating a specific cable - Toner probe
