PLEASE learn to use code tags, they make reading and commenting on source code MUCH easier.

HINT: you can edit your post and add code tags.

Some formatting & indentation would not hurt either

There are multiple issues with the original posted code.

Hi thankyou adding it into one file does make it easier but why when I try to run the program I get no matching constructor for initialization of ListOfAutos?

Or to show the autos a bit more meaningfully, and to show where you can update the display format from mine:

Place the number of Automotives you would like to enter: 2
Enter the Automotive chasssis-Number: 123
           Enter the Automotive make: Ford
          Please enter Vehicle model: Ranger
               Please enter car type: Truck

Enter the Automotive chasssis-Number: 4567

          Please enter Vehicle model: Civic

It compiled OK with MS VS 2019 (latest updates). Which compiler and C++ version are you using? What's the error message actually saying?
Denvor (14)
i am using qt 4.7.1 enterprise and this is the exact error code
no matching constructor for initialization of ListOfAutos
seeplus (6591)
qt 4.7.1 was released Nov 2010 and only supports C++98. It is absolutely out of date! You really need to update to qt 6 which supports C++17 or another compiler which supports at least C++17.

@Denvor Please do NOT delete your question after getting your answer. It makes the thread incomprehensible, and useless as a learning resource for others.
