Extend the functionality of cout by implementing a friend function in Number.cpp that overloads the insertion operator. The over

loaded insertion operator returns an output stream containing a string representation of a Number object. The string should be in the format "The value is yourNum", where yourNum is the value of the integer instance field of the Number class.Hint: the declaration of the friend function is provided in Number.h.Ex: if the value of yourNum is 723, then the output is:

Answer:

// In the number.cpp file;

#include "Number.h"

#include <iostream>

using namespace std;

Number::Number(int number)

{

   num = number;

}

void Number::SetNum(int number)

{

   num = number;

}

int Number::GetNum()

{

   return num;

}

ostream &operator<<(ostream &out, const Number &n)

{

   out << "The value is " << n.num << endl;

   return out;

}

// in the main.cpp file;

#include "Number.cpp"

#include <iostream>

using namespace std;

int main()

{

   int input;

   cin >> input;

   Number num = Number(input);

   cout << num;  

   return 0;

}

Explanation:

The main function in the main.cpp file prompts the user for the integer value to be displayed. The Number file contains defined functions and methods of the number class to set, get and display the "num" variable.

python Write a function that computes a future investment value at a given interest rate for a specified number of years. The fu
Svetlanka [38]

Answer:

def future_investment_value(investment, monthly_interest_rate, years):

  print("Years\tFuture Value")

  print("- - - - - - - - - - -")

  for i in range(1, years+1):

      future_value = investment * ((1 + monthly_interest_rate) ** (12 * i))

      print(i, "\t\t", format(future_value, ".2f"))

investment = float(input("Enter the invesment amount: "))

interest = float(input("Enter the annual interest rate: "))

year = int(input("Enter the year: "))

future_investment_value(investment, interest/1200, year)

Explanation:

Inside the function:

- In the for loop that iterates through the years, calculate the future value using the formula and print the results

Then:

- Ask the user for the investment, annual interest rate, and year

- Call the function with the given inputs

Select the correct text in the passage.
sergejj [24]

Answer:

2. Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano.

Explanation:

The options are:

1. Before a volcano erupts, earthquake activity beneath the volcano decreases.2. Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano.3. When a volcano erupts, the amount of carbon dioxide and sulfur dioxide emitted decreases. 4.Scientists measure the amount of these gases to determine the amount of magma present in the volcanic reservoir.

The answer is certainly 2. as seismometers are being used to find out the details of the earthquake activities which occur inside a volcano. And with this information, the volcanologists then predict the eruption of that particular volcano. Hence, the 2nd option does not have any factual errors, and all the others have factual errors.

Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255
maxonik [38]

Answer:

Follows are the code to this question:

#include <iostream>//defining a header file

using namespace std; //using namespace

int main() //defining main method

{

int red,green,blue,s; //defining integer variable

cout<<"Enter value: \n ";//print message

cin>>red>>green>>blue; //input value

if(red<green && red<blue)//defining if block that checks red value

s=red;//store red variable value to s variable

else if(green<blue)//defining else if block that checks green value less then blue

s=green;//store green variable value in s variable

else//defining else block

s=blue; //store blue variable value in s variable

//calculating red, green, blue value

red=red-s;//store red value

green=green-s;//store green value

blue=blue-s;//store blue value

cout<<red<<" "<<green<<" "<<blue;

}

Output:

Enter value:

130  

50

130

80 0 80

Explanation:

In the above code, inside the Main method, four integer variable "red, green, blue, and s" is defined, in which "red, green, and blue" is used for input the value from the user end.

  • In the next step, a conditional statement is used, that checks the red variable value, if the condition is true, it will store its value in the "s" variable, otherwise, it will go to else if block.
  • In this block, the green variable checks its value less than then blue variable value, if the condition is true, it will store the green value in the "s" variable, otherwise, it will goto else block.
  • In this block, it will store the blue variable value in the "s" variable, and subtract the value of "red, green, and blue" value from "s" and store its value, and at the last, it will print its value.

If the computer has an encrypted drive, a ____ acquisition is done if the password or passphrase is available. a. passive b. sta
Aleonysh [2.5K]

Answer: C. Live

Explanation:

A live acquisition is where data is retrieved from a digital device directly via its normal interface such as activating a computer and initiating executables. Doing so has a certain level of risk because data is highly likely to be modified by the operating system. The process becomes significantly more common likely with less available disk space to the point of completely impractical to image.
