The problem with understanding Enum - I can not figure out how to search in a jagged array and how to compare data in a jagged array using Enum . If it's not difficult for you, show or explain how for stupid. Here is what is:

  class Program { // 1) declare enum ComputerType enum ComputersType { Desktop = 0, Laptop = 1, Server = 2, } // 2) declare struct Computer struct Computer { public ComputersType comp; public int CPU; public float HGz; public int memory; public int HDD; } static void Main(string[] args) { // 3) declare jagged array of computers size 4 (4 departments) var departmentComputers = new Computer[4][]; // 4) set the size of every array in jagged array (number of computers) departmentComputers[0] = new Computer[5]; departmentComputers[1] = new Computer[3]; departmentComputers[2] = new Computer[5]; departmentComputers[3] = new Computer[4]; // 5) initialize array // Note: use loops and if-else statements Computer Desktop = new Computer(); { Desktop.comp = ComputersType.Desktop; Desktop.CPU = 2; Desktop.HGz = 1.6F; Desktop.memory = 4; Desktop.HDD = 200; } Computer Laptop = new Computer(); { Laptop.comp = ComputersType.Laptop; Laptop.CPU = 2; Laptop.HGz = 1.6F; Laptop.memory = 4; Laptop.HDD = 200; } Computer Server = new Computer(); { Server.comp = ComputersType.Server; Server.CPU = 2; Server.HGz = 1.6F; Server.memory = 4; Server.HDD = 200; } departmentComputers[0][0] = Desktop; Computer[] department; int computerIndex; department = departmentComputers[0]; computerIndex = 0; for (var i = 0; i < 2; i++) department[computerIndex++] = Desktop; for (var i = 0; i < 2; i++) department[computerIndex++] = Laptop; for (var i = 0; i < 1; i++) department[computerIndex++] = Server; department = departmentComputers[1]; computerIndex = 0; for (var i = 0; i < 3; i++) department[computerIndex++] = Laptop; department = departmentComputers[2]; computerIndex = 0; for (var i = 0; i < 3; i++) department[computerIndex++] = Desktop; for (var i = 0; i < 2; i++) department[computerIndex++] = Laptop; department = departmentComputers[3]; computerIndex = 0; for (var i = 0; i < 1; i++) department[computerIndex++] = Desktop; for (var i = 0; i < 1; i++) department[computerIndex++] = Laptop; for (var i = 0; i < 2; i++) department[computerIndex++] = Server; // 6) count total number of every type of computers // 7) count total number of all computers // Note: use loops and if-else statements // Note: use the same loop for 6) and 7) for (var x = 0; x < department.GetLength(x); x++) { for (var y = 0; y < department.GetLength(y); y++) { for (int k = 0; k < departmentComputers[x][y]; k++)

And then I sit the second day and nothing happens.

    I do not understand why you are looking only in one department = departmentComputers[3];

      foreach (var i1 in department) { Console.WriteLine(i1); Console.WriteLine(i1.comp); Console.WriteLine(i1.CPU); Console.WriteLine(i1.HDD); Console.WriteLine(i1.HGz); Console.WriteLine(i1.memory); }

    So it will look for all

     var c = new Computer[][] { departmentComputers[0], departmentComputers[1], departmentComputers[2], departmentComputers[3] }; foreach (var i1 in c) { foreach (var i2 in i1) { if (i2.comp == ComputersType.Server) { Console.WriteLine("Server ============================"); } else { Console.WriteLine("?============================="); } //Так можешь использовать номер enum Console.WriteLine("ComputersType=" + i2.comp + "=" + (int)i2.comp); //Console.WriteLine(i2); Console.WriteLine(i2.comp); Console.WriteLine(i2.CPU); Console.WriteLine(i2.HDD); Console.WriteLine(i2.HGz); Console.WriteLine(i2.memory); } }
    • this is not a search, this is an array declaration: department = departmentComputers [3]; question :: how to use Enum, struct, jagged array, hiccup data and manipulate this data. - Despoil
    • in the usual ways. bring something concrete, specific actions with any values. I do not know why you enum and how you are going to use it. - codename0082016
    • Enum, this is the condition of the task, what needs to be done .. in the example it is marked as // 1) and so on until // 7). I do tasks 1 to 5, but at 6.7 I can’t do it, even though they seem to be easy! - Despoil
