Percentage Calculation

Program Plan:

ADT interface filename: “Percent.h”

  • Include required header files.
  • Define a class “Percent”.
    • Declare function for overload operator “==” and “<”.
    • Declare default constructor for “Percent” class.
    • Declare a constructor for “Percent” class with one integer parameter.
    • Declare function for input overload operator and output overload operator.
    • Declare function for binary overload operators “+”, “-” and “*”.
    • Declare a member variable “value”.

ADT implementation filename: “Percent.cpp”

  • Include required header files.
  • Define default constructor for “Percent” class.
    • Here assign the value of “value” to “0”.
  • Define constructor for “Percent” class with one integer parameter “percentValue”.
    • In this constructor, assign “value” to “percentValue”.
  • Define a function for overload operator “<”.
    • This function is used to check whether the first percent is less than second percent or not.
  • Define a function for overload operator “==”.
    • This function is used to check whether the two percent’s are equal or not.
  • Define a function for input operator “>>”.
  • Define a function for input operator “<<”.
  • Define a function for binary overload operator “+” to compute the sum of two percentages.
    • In this function, create an object “sum”.
    • Then compute the addition of two percent’s.
    • Finally returns the result of addition.
  • Define a function for binary overload operator “-” to compute the subtraction of two percentages.
    • In this function, create an object “s”.
    • Then compute the subtraction of two percent’s.
    • Finally returns the result of subtraction.
  • Define a function for binary overload operator “*” to compute the multiplication of one percent and an integer value.
    • In this function, create an object “m”.
    • Then compute the multiplication of one percent and an integer value.
    • Finally returns the result of multiplication.

Application filename: “main.cpp”

  • Include required header files.
  • Define main function.
    • Create two objects “percent1” and “percent2” from “Percent” class.
    • Create an object “percent3” with one integer parameter “10”.
    • Declare an integer variable “intValue”.
    • Read the percentage 1 and percentage 2 from user.
    • Check the two percentages using “==” operator.
    • Check the two percentages using “<” operator.
    • Create an object “sumPercent” from “Percent” class.
    • Then compute and display sum of two percentages.
    • Create an object “subPercent” from “Percent” class.
    • Then compute and display difference of two percentages.
    • Display percentage 3 from assigned value.
    • Read an integer from user to multiply with a percentage 3.
    • Finally compute and display the multiplication of “percent3” and a user entered integer value.

Why is Linux popular? What would make someone choose a Linux OS over others? What makes a server? How is a server different from a workstation? What considerations do you have to keep in mind when choosing between physical, hybrid, or virtual server and what are the reasons to choose a virtual installation over the other options?
Objective  you will: 1. Implement a Binary Search Tree (BST) from scratch, including the Big Five (Rule of Five)  2. Implement the TreeSort algorithm using a in-order traversal to store sorted elements in a vector. 3. Compare the performance of TreeSort with C++'s std::sort on large datasets. Part 1: Understanding TreeSort How TreeSort Works TreeSort is a comparison-based sorting algorithm that leverages a Binary Search Tree (BST): 1. Insert all elements into a BST (logically sorting them). 2. Traverse the BST in-order to extract elements in sorted order. 3. Store the sorted elements in a vector.  Time Complexity Operation                                Average Case     Worst Case (Unbalanced Tree)Insertion                                     0(1log n)                0 (n)Traversal (Pre-order)                  0(n)                       0 (n)Overall Complexity                  0(n log n)                 0(n^2) (degenerated tree) Note: To improve performance, you could use a…
I need help fixing the minor issue where the text isn't in the proper place, and to ensure that the frequency cutoff is at the right place. My code: % Define frequency range for the plot f = logspace(1, 5, 500); % Frequency range from 10 Hz to 100 kHz w = 2 * pi * f; % Angular frequency   % Parameters for the filters - let's adjust these to get more reasonable cutoffs R = 1e3; % Resistance in ohms (1 kΩ) C = 1e-6; % Capacitance in farads (1 μF)   % For bandpass, we need appropriate L value for desired cutoffs L = 0.1; % Inductance in henries - adjusted for better bandpass response   % Calculate cutoff frequencies first to verify they're in desired range f_cutoff_RC = 1 / (2 * pi * R * C); f_resonance = 1 / (2 * pi * sqrt(L * C)); Q_factor = (1/R) * sqrt(L/C); f_lower_cutoff = f_resonance / (sqrt(1 + 1/(4*Q_factor^2)) + 1/(2*Q_factor)); f_upper_cutoff = f_resonance / (sqrt(1 + 1/(4*Q_factor^2)) - 1/(2*Q_factor));   % Transfer functions % Low-pass filter (RC) H_low = 1 ./ (1 + 1i * w *…
