Please master teach how to new a class

冥冥中

//The call of the constructor is the same as the ordinary function. If you don’t even know ordinary functions, go back and read a book first.
CActiveProcess* p = new CActiveProcess("name1","sname2","sname3","sname4",
                                       "sname5","sname6","rname1","rname2","rname3", "help",&ture)

booook

I have never seen such a long parameter. I have read it all, and dropped two commas.

CActiveProcess *activeProcess =
new
CActiveProcess(
param1,param1,param1,
param1,param1,param1,param1,
param1,param1,param1,param2,
param2 ,param3 );

心碎飞了

CActiveProcess* one = new CActiveProcess;
Will this be wrong? If it’s really wrong... (don’t understand)

According to the definition in the book:
Type name * pointer variable name = new type name (if there is a constructor with parameters, assign initial values ​​to the parameters)
//If it is not in (), do not write, the compiler will automatically call the default constructor


new CActiveProcess(char *sname1,char *sname2,char *sname3,
char *sname4,char *sname5,char *sname6,char *rname1,
char *rname2,char *rname3,char*help,float*ture, float*error,__int32 *finger);

//Of course it’s not possible to write this way, because variables like *sname2 are waiting for us to assign values, so let me change it casually:
//CActiveProcess* one=new CActiveProcess(a,b,c,d,e,f,g,h,i,help,ture, false,1);
//Probably that's it

Thank you, everyone. I am almost a beginner, and I am now in the practice stage, which makes everyone laugh. There is still a lot to learn, thank you again for your enthusiasm.

Beginners wrote very amazing constructors, very clever.

If there are many parameters passed, it is better to design a structure to encapsulate it, which is cleaner.

gosh. . . This is obviously a class library of mfc or vcl. . . . .

If MFC is designed in this way, it should not be in line with Microsoft's style.
As soon as there are more parameters, he will come up with n more structures

VCL should not appear, after all, it was written by Delphi

More parameters are better encapsulated into classes or structure

The content contained in the name CActiveProcess will not be written by people at the level of lz. Besides, if lz can write such a constructor. If you don't call it, it's even more incredible. .

Thank you very muchdiamond52; for telling me the truth, it seems that the basics are too unreliable. Go back and read the book carefully, thank you!
