How to run the code after finishing writing it in Qt?

In Qt, you can execute code by following these steps:

1. Click on the green play button in the bottom left corner of the Qt Creator interface, or use the shortcut Ctrl + R, or click on the “Build” option in the menu bar and then select “Run”.
2. Qt Creator will automatically compile and build your code, then display the running result in a new window.
3. If the code includes a user interface, you can interact with it to see how the code runs.
4. If the code is error-free and compiles successfully, you can see the output of the code in the running window.

Before running the code, make sure to select the correct compilation suite, such as the proper compiler and target platform. This can be set in the toolbar of Qt Creator. Additionally, if the code uses external dependency libraries or resource files, make sure to properly add them to the project and build them before running.
