For many years, computers sold with the Windows operating system would contain a game called M inesweeper. The player would be presented with a grid, where they would have to click an empty part of the map. If they clicked on a hidden mine, the game would be instantly over. However, if they clicked a safe spot, a hint about nearby mines would be displayed and the player would click another spot. The goal would be to flag all the hidden mines without hitting one. (As an aside, many people did not know these rules and just clicked around randomly until they hit a mine)We will be developing a simplified version of this game. You will prompt the user for a grid size and then created a 2D array with equal width and height (C++ students: Check the Appendix for more information on how to do this). You will initialize the 2D char array with each element equallying a ‘?’ symbol. You will then randomly generate one “mine” value per…
- Write the program of object orientation programming c++. Write a program with a class that contains an array of integers. Initialize the integer array in the constructor of the class. Then create two friend functions to the class to find the largest and smallest integers in the array. (One function should be global)Create a destructor that sets all of the elements in the array to 0.There is a class Team, that holds information about the team name, number of players in the team, and player’s code. Design the constructor function that decides the number of player in the team and initializes code for each player. Create a team and display its all data. In C++(Implement dynamic memory allocation).In C++ Syntax for arrays of objects classGrades allCS[15]; //the default constructor is applied to //all elements of this array //to set the number of students in each class to 25 for (i = 0; i < 15; i++) { allCS[i].setNumStudents(25); } //Assume values in all classes. Write the code to print all class averages?

This class must have methods that do the following: Add a new item to the inventory manager. Remove an item from the inventory manager. Re-stock an item in the inventory manager. Display the items in the inventory manager. Search for an item in the inventory manager by at least two criteria (name, price, quantity, etc.). Test the inventory manager class with a driver program or unit tests. This may be a console application.Use java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format.

How to decide if your variable should be declared as an enum type or any other data types? Support your answer with examples.Term by CodeChum Admin (JAVA CODE) Construct a class called Term. It is going to represent a term in polynomial expression. It has an integer coefficient and an exponent. In this case, there is only 1 independent variable that is 'x'. There should be two operations for the Term: public Term times(Term t) - multiplies the term with another term and returns the result public String toString() - prints the coefficient followed by "x^" and appended by the exponent. But with the following additional rules: if the coefficient is 1, then it is not printed. if the exponent is 1, then it is not printed ( the caret is not printed as well) if the exponent is 0, then only the coefficient is printed. Input The first line contains the coefficient and the exponent of the first term. The second line contains the coefficient and the exponent of the second term. 1·1 4·3 Output Display the resulting product for each of the test case. 4x^4
