Research assistants provide support to professionals who are conducting experiments or gathering andanalyzing information and data. Suppose you are working as RA (research assistant) with a Professor who isworking on a project and evaluating complex mathematical equations. Your duty is to assist him, so in thisregard he has assigned a task to you. Your task is to write a oop c++ program to create a class named equation which will have the data members a, b and c which are the coefficients of the quadratic equation. The class will have two more data members namely proot and nroot which stand for the positive root and negative root of the equation. Suppose that variables a, b and c are integers. Where proot and nroot are floats. Input Function to get values of a, b and c Then design a friend function which will determine the proot and nroot of the equation. Create another friend function which will display the values of proot and nroot.
C++ solution required Gustavo Gus has to remove one of his drug chemists due to trust issues. So he comes up with the idea of playing a game of Pick and Drop. In this game, an array of integers AA is of size NN, and each player (Mr. Hyperwhite and Gale BoetticherGaleBoetticher) removes one number from the array in alternating moves until only one number remains. If the remaining number is even, Mr. White wins, otherwise Gale wins. Whoever loses will be eliminated by Gus. Mr. White always takes the first turn (i.e., Mr. White first turn -> Gale second turn -> Mr. White third turn and so on). Mr. White is thinking about which number to choose in the first move to win. Help Mr. White by determining the number of ways he can pick the first number to win. Input 1 5 12345 Output -1
Question 5 Write the code for the function printRoster, it should print out the contacts in a format similar to the example. You can use a range-based for-loop and auto to simplify the solution, if you wish. #include #include #include #include #include using namespace std; void printRoster(map>>& roster) { // Fill code here int main() { map>> roster; roster["ELCO"]["CS-30"]. emplace_back("Anthony Davis"); roster["ElCo"]"cS-30"j. emplace_back("Talen Horton-Tucker"); roster["ElCo"Ï"BUS-101"].emplace_back("LeBron James"); roster["SMC"]["CHEM-101"].emplace_back("Russell Westbrook"); printRoster(roster); return 0; Here is the sample output: ElCo BUS-101: LeBron James CS-30: Anthony Davis Talen Horton-Tucker SMC CHEM-101: Russell Westbrook

: A designer in 3D graphics company wants to design a matrix as a two-dimensional array. The size of 2D array could be the last two digit of arid number. Initially he creates a class matrix that provides the member function to check that no array index is out of bounds. Make the member data in the matrix class a 10-by-10 array. A constructor should allow the programmer to specify the actual dimensions of the matrix (provided they’re less than 10 by 10). The member functions that access data in the matrix will now need two index numbers: one for each dimension of the array. Here’s what a fragment of a main() program that operates on such a class might look like: If my Arid Number is 20-Arid-254 then: // in case of zero consider next digit matrix m1(5, 4); // define a matrix object int temp = 12345; // define an int value m1.put(3, 4, temp); // insert value of temp into matrix at 3,4 temp = m1.get(3, 4); // obtain value from matrix at 3,4
Can I please get help writing this in C++ Write a class called Word that stores a word from a product review in a data member called “word.” The class should also contain an integer variable representing the number of times (i.e. frequency) that the word was found in a product review document. The class should have a one-argument constructor that receives a pointer to a c-string (character array) containing the word as its one parameter. (Note that the output of the strtok_s function described above is a pointer to a c-string containing the word that was parsed. This is what you will pass in to the Word constructor.) The Word constructor should also set the frequency of this Word object to 1. Appropriate set and get functions should be included for both the word and frequency data members. Write a class called Review that contains a vector of objects of the Word class. The class should contain functions to add a new Word object to the vector and to print out all of the Words in…
