Recently, you need to use C + + and C # mixed programming, and then write a demo of C # calling DLL generated by C + +. What bothered me for a long time was how the string type in C + + was expressed, and now writes the C + + generated DLL for the C

Write a C + + program:There are two methods of vector initialization:Vectorelem_seq (seq_size);Elem_seq[0]=1elem_seq[1]=2;Another method is to use an initialized array as the initial value of the vector.int

Currently the collection is used by the array and list, now the 2 array and list of the sort, do some testing:First on chestnuts:            int32[] _testsort = new  int32[] { 1, 4, 2, 6, 8, 18, 3, 5, 9, 7, 11,  10 };            array.sort

C language Coercion type conversion is too rough , any type can be converted between, compilation is difficult to judge its correctness; difficult to locate , in the source code can not quickly locate all the use of coercion type conversion

Review the list and write aThis is always confusing to me is & ... Would have thought & equivalent *,,,,,, take the content, take the address ...But when you're done, you find it, *&!. =& (node *p);What he's saying is that what I need in the

Syntax: const char *C_STR (); the C_STR () function returns a pointer constant to the normal C string, with the same contents as this string string. This is to be compatible with the C language, there is no string type in C, so the string object

Read the code of the predecessor this morning and see the code as follows:1 Lock ("Execute") 2 {3 string sqlstr = sbsqlscript.tostring (); 4 }When I see the first sentence, I wonder if the lock in C # can be used this way? It was a usage

In C #, the Out keyword is the argument value converted to passed by reference. Out keyword is useful when multiple values are returned at the same time.Similar to ref keyword. If using out keyword argument, then the definition and use of the method

Class Library:To put it bluntly, it is to let others call you to write the method, and do not let others see how you achieve.If there is a function you do not do and need help from others, then your colleague can help you write a class and then you

The primary class:public class Tclass{int parameterpublic static void Showint (int iparameter){Console.WriteLine ("Here is Tclass showint{0}, type {1}", Iparameter,iparameter.gettype ());}Long parameterpublic static void Showlong (Long

In the study of the code written by predecessors, always do not understand. What is the corresponding relationship between the index of the citation in Word and the index in the table of citations? How does it correspond? I think, yesterday and

[Noi 2.5 _ 7834] is divided into dfs, noi2.5 _ 7834 There are two dfs methods: 1. Save the number of each group and its prime factor. Each time a new number is compared with each group to determine whether the group is of mutual quality, and then
