Structural body

1. Concept:

A struct is a data structure written outside of the main function, composed of different types of data, which are interconnected by data in a single whole.

2. Declaration method:

struct Structure Body name

{

Member variables (consisting of type name + member name)

}

Cases:

 Public struct student//publicis a modifier that can be added without the scope of the entire namespace {publicint Code ; // define variables, each variable is called a property of a struct  Public string Name;  Public string Sex;  Public int Age ;  Public decimal Height;}

3. Call Method:

(1) Initialize the struct (new one)

(2) Assigning values to variables in a struct

Such as:

// continue to use the definition of the structure above New  101"Zhangsan" "Nan" = 173; 

4, using the structure of the code to optimize the processing

Title: Enter the number of students, enter the name, height, age, average age, and then according to the height of ascending discharge

Idea: Create a structure with name, height, and age parameters, and then set up a set that puts the structure type of each initialization into the collection with three of data through a for loop.

Answer:

Console.WriteLine ("Enter the number of students:");intn =int. Parse (Console.ReadLine ()); ArrayList ar=NewArrayList ();//set up collection fill dataintsum =0; for(inti =0; I < n; i++) {Student SS=Newstudent (); Console.Write ("Please enter your name:"); Ss. Name=Console.ReadLine (); Console.Write ("Please enter your age:"); Ss. Age=int.    Parse (Console.ReadLine ()); Console.Write ("Please enter your height:"); Ss. Height=int. Parse (Console.ReadLine ().    Trim ()); Ar. ADD (ss);//Add a student type of data to the collectionsum = Sum+ss. Age;//Calculate Total Score} for(inti =0; I < n; i++){     for(intj = i; J < N; J + +)    {        //Establish intermediate values, convert ar[i], ar[j] to the type of student, and then judge the heightStudent S1 =(student) ar[i]; Student S2=(student) ar[j]; if(S1. height<S2. Height) {Ar[i]=S2; AR[J]=S1; }    }}foreach(Student Ainchar) {Console.Write ("Name:"+a.name); Console.Write ("Height:"+a.height); Console.Write ("Age:"+a.age); Console.Write ("\ n");}
