New project
After we open QTCreator, click File-- New File and Project
Select a console application
Change its name to HelloWorld
Go on to the next step, and the next step will be done.
This generates our project.
Add # include to it
And then add it to the code
Then click the green triangle symbol in the lower left corner, which will prompt you to save it and run it directly.

At this time, a new line is displayed after printing Hello World in the console. Please enter your name:
We enter Vaccae
Click enter again to print out the Hello World Vaccae
The first Hello World is complete!
