- IN C++ USING CLASS Write a program in C++ that implements the game tic-tac-toe: Tic-Tac-Toe is a game played on a three-by-three board. Two players, X and O, alternate in placing their respective marks in the cells of this board, starting with player X. If either player succeeds in getting three of his or her marks in a row, column, or diagonal, then that player wins. In this homework, you should use the OOP concepts to implement the tic-tac-toe gameWrite the following three functions in c programming language: a) The function gets an array A of length n of ints, and a boolean predicate pred. It returns the smallest index i such that pred(A[i])==true.If no such element is not found, the function returns -1.int find(int* A, int n, bool (*pred)(int)); b) The function gets an array A of length n of ints, and a function f. It applies f to each element of A.void map(int* A, int n, int (*f)(int)); c) The function gets an array A of length n of ints, and a function f. The function f gets 2 ints and works as follows: Start with accumulator = A[0] For i=1...length-1 compute accumulator=f(accumulator, A[i]) Return accumulator For example, if f computes the sum of the two inputs, then reduce() will compute the sum of the entire array.int reduce(int* A, int n, int (*f)(int,int));solve the problem in java:Consider the are n=2 subjects and needed =[4,5]answered questions, to pass.The student has answered =[2,4] questions in the two subjects so far, and can answer another q=1 questions across all subjects combined. The best outcome is to answer an additional question in the second subject on order to pass it, as 2 more answers required to pass the first subject. the max number of subject s that can be passed is 1. the function must return an integer that can represent the max number of subjects that can be passed. public static int maxNumsub(List <Integer> answered, List<Integer> needed, int q){//write code here}
- (Program) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters, such as zerocount, onecount, twocount, and so forth, to 0. Then generate a large number of pseudorandom integers between 0 and 9. Each time 0 occurs, increment zerocount; when 1 occurs, increment onecount; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of time they occurred.Write a program in C++ using C-style and array to allow the user to calculate the distance between cities on a map. Sounds pretty complicated, eh? Don't worry, we'll make a few simplifications here: The distances are calculated in map units on the 2D map. Each city is given a set of coordinates relative to some point on the map. We'll call this origin (0,0). There can only be a finite number of cities in the system at a given time (you decide this maximum). But in order to make the system useful, we'll have to add a few other features: Each city has a name in addition to its coordinates (you can assume a maximum length for these names; but they must be able to hold spaces: Los Angeles, New York, etc.). The user selects what action to take from a menu: 1) Enter city Information 2) calculate Distance between two cities 3) Print All cities 4) Quit Make sure you allow them to choose their options by both the number and the capitalized letter(s) of the choice. They cannot…Write a function in c++ is ordered that takes an integer array and its size as parameters and returns true if the array elements are ordered in nondecreasing order and returns false if not. For example, integers in {10,0,1,1,5,1009} are ordered in nondecreasing order. On the other hand, integers in {1, 2, 3, 8, 4, 19} are not since 8 > 4
- Edsgar Dijkstra is known for his work on programming languages. Hecame up with a neat problem that he called the Dutch National Flagproblem: given a list of strings, each of which is either 'red', 'green', or 'blue'(each is repeated several times in the list), rearrange the list so that thestrings are in the order of the Dutch national flag—all the 'red' stringsfirst, then all the 'green' strings, then all the 'blue' strings.Write a function called dutch_flag that takes a list and solves this problem.Write a C++ program to create a Class of magi with data members of type double x and y and one constructor to initialize the values of x and y. Perform addition operations on complex data using class and object. The program should ask for the real and imaginary parts of two complex numbers, and display the real and imaginary parts of their sum.Please write a C ++ program that uses “class” to calculate ”Sets“. for example , calculate the union of two sets A and B ,or Cartesian product of two sets A and B , or the intersection of A and B.
- Write a program in c language to analyze the letter frequencies in a block of text. Ignore case (upper and lower count the same). It should count the number of times each letter appears in the text, the number of times each pair of letters appears, and the number of times each sequence of 3 letters appears. Your program should sort the counts of single letters, pairs of letters (bigrams), and triples of letters (trigrams), then print the non-zero values in decreasing order. For single letters, print all non-zero values; for bigrams and trigrams, print the first 30 non-zero values.(monoalphabetic substitution ciphers)code required for python: For this question, you will be required to use the binary search to find the root of some function f(x)f(x) on the domain x∈[a,b]x∈[a,b] by continuously bisecting the domain. In our case, the root of the function can be defined as the x-values where the function will return 0, i.e. f(x)=0f(x)=0 For example, for the function: f(x)=sin2(x)x2−2f(x)=sin2(x)x2−2 on the domain [0,2][0,2], the root can be found at x≈1.43x≈1.43 Constraints Stopping criteria: ∣∣f(root)∣∣<0.0001|f(root)|<0.0001 or you reach a maximum of 1000 iterations. Round your answer to two decimal places. Function specifications Argument(s): f (function) →→ mathematical expression in the form of a lambda function. domain (tuple) →→ the domain of the function given a set of two integers. MAX (int) →→ the maximum number of iterations that will be performed by the function. Return: root (float) →→ return the root (rounded to two decimals) of the given function. my code below , however as…Write a C++ program to read the cus_name, cus_id of 5 Customers using array of structures and then print the names in descending order (z to a) with their corresponding id .The program must contain 3 functions for the following: • void reading(Customer c[],int size) :- for reading cus_name and cus_id. • void printing(Customer c[],int size ):- for printing cus_name and cus_id. • void sorting(Customer c[],int size) :- for sorting the names z to a (reverse of alphabetically)
