I m depressed, I ve been reading the book for a week, I ve read VC 6, can t I make up helloworld?

The program you wrote is itself wrong, so it's not that you can't make it, it's that you make it wrong.

If you have created an incorrect working interval and have made up an incorrect **, it is recommended that you find a practical training guide. First "copy", then "imitate", and finally innovate.

include because you want to call system("pause");So add this.

#include

using namespace std;

int main()

int a = 0;

cout<<"s"return 0;

Also、Your file type is。 This is wrong, it should be. CPP is right、Pay attention when you create a new file、

#include

using namespace std;

int main()

cout<<"s"Hehe, it's been compiled, your problem is that you haven't figured out the concept.

Why can't it, just write it on the cpp.

Create a win32 console project, and select an empty project in the next step.

Select C++ Resource File (CPP) to create a new fileto the project you just had.

In cpp, type:

#include

using namespace std;

int main()

Just run it.

dev-c++：

#include

using namespace std;

int main()

Just debug and run.

Just press f9 and you're good to go!

It should be written wrong in main.,Check if it's written as mian, a very complicated program?,Send it up and see.

Then it could be a problem with installing the software... Or the engineering, the file is not set up correctly?

I changed the running program main to mian, and the error you said will appear when compiling, but it won't run. You can package the project files and contact me directly.

You press the green triangle execution button, this is debugging and running, and the crash is normal, because there is no waiting and pausing statement in the program.

Press Ctrl+F5 to execute the program, and you can see the execution result.

Your ** has been successfully compiled, there are no errors, when it runs, because the normal operation is completed, so the window is automatically closed, and it can't be called flashback. Because your program isn't letting the user type or waiting for the user to type.

1: You can run with non-debugging, or use CTRL+F5. or a non-debugging run in the menu.

2: You can add a statement that reads user input, such as read, get, etc., waiting for user input.

It is recommended to run directly with non-debugging. This does not affect the logic.

There is no best, only better, hehe!

If it's an entry, it's a general domestic book to lay the foundation.

If you go deeper, just take a look at "In Plain Terms" Hou Jie's, "Windows Core Programming", "MFC Windows Programming", etc., the latter two are foreign, I don't remember the author's name, you have to find it yourself, if you really want to study in depth, it's best to buy these books. Hope it helps.

Windows Programming (2nd Edition) Yanping Wang.

This book is very good, the introduction is easy to understand, and its e-book and source ** are easy to find online, of course, it is best to buy this book.

Pulse VC++ is pretty good, don't believe you to check it, and the aftermath is also very good.

Bad link? It should be that the program you ran before was not closed.

Is it because the running exe is not closing?

Because you didn't close it, there was an error when recompiling the generated exe file.
