use c++ programming language to create a derived, or child class for Cylinder, that is, a Cone class. The same function, with the same parameters, is used. However, the formula is different for a cone. // The formula is: V = (1/3) * pi * (r^2) * h

I need a C code of this. Create a program that implements the functions of a quadratic equation. I have also attached an image in what would the quadratic formula be.    STRUCTURE DEFINITION OF A QUADRATIC EQUATION   typedef struct{            float a;            float b;            float c; }Quadratic; Implement the following functions:   void discriminant(Quadratic *q, float a, float b, float c);            - Initialize coefficients of Quadratic q.   int isImaginary(Quadratic *q);            - Returns 1 if discriminant is less than 0, else returns 0.   float firstRoot(Quadratic *q);            - Returns the first root of the equation.   float secondRoot(Quadratic *q);            - Returns the second root of the equation.   void display(Quadratic *q); -Prints the coefficients a, b, c.   int getValue(Quadratic q, int x);   -Given value of x, substitute it in the quadratic -example: 2x^2 + 3x + 3 ; x = 2; therefore getvalue will return 17. The task is to implement the functions. And to…

javascript Need help defining a function frequencyAnalysis that accepts a string of lower-case letters as a parameter. frequencyAnalysis should return an object containing the amount of times each letter appeared in the string. example  frequencyAnalysis('abca'); // => {a: 2, b: 1, c: 1}

Hello, I'm working on this hangman simulation in C++. The code runs but it doesn't count wrong guesses after one letter is guessed correctly. Also, the body of the hangman comes out wrong. Could you help?         #include<iostream>#include<cstring> // for string class functions#include<fstream>#include <cctype>using namespace std; int main(){    // define variable to get the response from user "Yes" or "No"    string response;    // Define index variable    int w = 0;    // define number of words that need to be guessed by the user assume 4    const int WORDS = 4;        // loop    do    {        // we will define the hangman body        const char body[] = "o/|\\|\\";        // here we define the words        string words[WORDS] = {"MACAW", "SADDLE", "TOASTER", "XENOICIDE"};        // fetch size or length        string xword(words[w].length(),'*');        // define iterator to fetch the words        string::iterator ix = xword.begin();        string::iterator i…

Write a simple trivia quiz game using c++ Start by creating a Trivia class that contains information about a single trivia question. The class should contain a string for the question, a string for the answer to the question, and an integer representing the dollar amount the question is worth (harder questions should be worth more). Add appropriate constructor and accessor functions. In your main function create either an array or a vector of type Trivia and hard-code at least five trivia questions of your choice. Your program should then ask each question to the player, input the player’s answer, and check if the player’s answer matches the actual answer. If so, award the player the dollar amount for that question. If the player enters the wrong answer your program should display the correct answer. When all questions have been asked display the total amount that the player has won.

This is in c++. Create a class of function objects called StartsWith that satisfies the following specification: when initialized with character c, an object of this class behaves as a unary predicate that determines if its string argument starts with c. For example, StartsWith(’a’) is a function object that can be used as a unary predicate to determine if a string starts with an a. So, StartsWith(’a’)("alice") would return true but StartsWith(’a’)("bob") would return false. The function objects should return false when called on an empty string. Test your function objects by using one of them together with the STL algorithm count_if to count the number of strings that start with some letter in some vector of strings. So basically, I want a class that returns true or false based on if the name that is typed starts with the character that I put down.

write a C++ program to Create a time class that includes integer member values for hours, minutes,and seconds.Make a member function get_time() that gets a time value from the user, and a functionput_time() that displays a time in 12:59:59 format. Add error checking to the get_time()function to minimize user mistakes. This function should request hours, minutes, and secondsseparately,and check each one for ios error status flags and the correct range. Hoursshould be between 0 and 23, and minutes and seconds between 0 and 59. Don’t input thesevalues as strings and then convert them; read them directly as integers. This implies thatyou won’t be able to screen out entries with superfluous decimal points, as does theENGL_IO program in this chapter, but we’ll assume that’s not important.In main(),use a loop to repeatedly get a time value from the user with get_time() andthen display it with put_time(), like this:Enter hours: 11Enter minutes: 59Enter seconds: 59time = 11:59:59Do another…

For C++ Programming II D.S. Malik Programming Exercise 10-16: Write the definition of a class swimmingPool, to implement the properties of a swimming pool. Your class should have the instance variables to store the length (in feet), width (in feet), depth (in feet), the rate (in gallons per minute) at which the water is filling the pool, and the rate (in gallons per minute) at which the water is draining from the pool. Add appropriate constructors to initialize the instance variables. Also, add member functions to do the following: determine the amount of water needed to fill an empty or partially filled pool, determine the time needed to completely or partially fill or empty the pool, and add or drain water for a specific amount of time, if the water in the pool exceeds the total capacity of the pool, output "Pool overflow" to indicate that the water has breached capacity. The header file for the swimmingPool class has been provided for reference. Write a program to test your…
