C # Basics Little Exercise

1. Accept the input numbers via the console, place the numbers in a one-dimensional array, reverse the data processing, and print the reversed to the console application

Method One

Steps:

1. Adding data variables for receiving console input

2. Convert the received string into a one-dimensional array

3. Create a new StringBuffer object to hold the inverted one-dimensional array

4. Use a For loop to add a one-dimensional array in reverse to the StringBuffer object

5. Convert the StringBuffer object through the ToString () method to a string and print

 /// <summary>        ///The input numbers are accepted via the console, placed in a one-dimensional array and implemented as an array for rollover data processing, and then the flipped data is displayed in the console. /// </summary>        /// <param name= "Numbers" ></param>         Public Static voidZhuanhuan (stringnumbers) {            //converts the obtained number into a one-dimensional array            Char[] Array =numbers. ToString ().            ToCharArray (); //Building a StringBuilder stringStringBuilder SB =NewStringBuilder (); //inserts the array in reverse to the constructed string             for(intI=array. length;i>=0; i--) {sb.            Append (array); }            //converts a StringBuffer object into a string and prints it through the ToString () methodConsole.WriteLine ("the inverted array is: {0}", sb.        ToString ()); }

Method Two bubble sort

Steps:

1. Adding data variables for receiving console input

2. Convert the received string into a one-dimensional array

3. Iterating through an array

4. Sorting

2. Define an employee class employee, which includes a static domain Totalsalary, implements the static constructors and instance constructors of the class, and realizes the function of outputting all employees ' salaries.

Code implementation:

//Employee ClassclassEmployee { Public Static DoubleTotalsaraly {Get;Set; }  Public DoubleSalary {Get;Set; }  Public stringEmployeeName {Get;Set; }  PublicEmployee (stringEmpName,Doublesalary) {             This. EmployeeName =EmpName;  This. Salary =salary; Employee.totalsaraly+=salary; }        StaticEmployee () {totalsaraly =0 D;}  Public Static DoubleGettotalsalarys () {returntotalsaraly; }         Public Doublegetsalary () {return  This.        Salary; }         Public Override stringToString () {returnString.Format ("the salary for {0} is: {1}. ", This. EmployeeName, This.        Salary); }    }//Main Methodemployee[] emp =Newemployee[3];emp[0] =NewEmployee ("Zhang San",5600.25); emp[1] =NewEmployee ("John Doe",8500.00); emp[2] =NewEmployee ("Harry",15000.88); Console.WriteLine ("the employee's total salary is: {0}\n", Employee.gettotalsalarys ()); Console.WriteLine ("the salary for {0} is: {1}\n", emp[0]. EmployeeName, emp[0]. Salary); Console.WriteLine (emp[1]. ToString ()); Console.WriteLine ("\n{0} 's salary is: {1}\n", emp[2]. EmployeeName, emp[2]. Salary);

3. Write a console program that includes 3 classes, where animal is the parent class, and dog and cat are subclasses derived from animal that define the sounds of various animal classes. Then, an object of 3 classes is created, which in turn shows the type and call of 3 objects.

Code implementation:

//Parent and Child classesclassAnimal { Public Virtual voidshout () {}}classCat:animal { Public Override voidShout () {Console.WriteLine ("cat bark: Meow cat meow--\n"); }    }    classDog:animal { Public Override voidShout () {Console.WriteLine ("The dog barks: Wang Bark--\n"); }    }//Main function Calllist<animal> list =NewList<animal>(); Animal Cat=NewCat (); Animal Dog=NewDog (); List.            ADD (CAT); List.            ADD (dog); foreach(Animal Ainchlist)            {a.shout (); }
