How make a application from code

Question

just can't understand we wrote code and after then??

Answer 1

When coding in an IDE, the likelyhood is that you've had to click "Build and Run" to actually run your program, and you must re-build after any changes you make to your code.

When you build and run, you are compiling the code you've written in to something the computer can understand and run.

If you want to have the application yourself in the form of a .exe, go to the directory where your project is located, and the .exe will be somewhere in there, commonly in a folder called "Debug" or just another sub-folder with the name of your project.
