Write some of the notes that you remember, which is another notebook.C#Data Typestring is a reference type; Int,double is a value type;string= string (not numeric/), int= Integer (not decimal) long= integer (larger than int); double (large value)

Union Common Body Description:When a common body is declared, the compiler automatically produces a variable whose length is an integer multiple of the maximum variable length in the union.For example, the union has {int x; double x1; char name[10];}

The random function is not an ANSI C standard and cannot be compiled under a compiler such as GCC,VC.     You can use the RAND function under C + + to implement it. 1. The C + + standard function library provides a random number generator RAND,

Enter a number to insert into the sorted queueFirst: Define an array of integers that are already lined upSuch as: int arry[7]={2,3,5,11,15,17};or enter an array of integers, and then sort (bubble, select All)Let's use the bubble Sort method:

(a) input a line of telegraph text, the letter into its next letter (such as ' a ' becomes ' B ' ... ' z ' becomes ' a ' other characters unchanged)(1) #include using namespace Std;int main () { int i=0; Char A[i]; while (Cin>>a[i]) {

1. IntroductionIn addition to calculating all the elements of a specific range, including successive parts and initial values, you can also use the specified binary operation to calculate the result of an element within a particular range. Its

"Struct"Two ways to define struct bodies struct student{};struct student a={10001, "in the Cloud", ' M ', "Beijing"}; struct student{}a={10001, "In the Cloud", ' M ', "Beijing"};Define struct-body array A to a[],struct student stu[3]={{..},{..},{...}

A constantA constant is a variable whose value is not changed during use. Const is added before constants when declaring and initializing constants. const int a = cannot;//This value is changed. There are at least 3 benefits to using constants in

1. Value type data in the stack, reference type data in the heap.2. Value types store the values of data directly, whereas reference types store references to data.3. Base class for value types: System.valuetype,system.valuetype is also inherited

Shallow copy: A new object reference address is copied to the object (it only gives a name to an object, so the corresponding property of the original object changes when a property of the copy is changed).The definition of a shallow copy-assigns
