Error: the program stops executing | Exit code: 255 - c++

Question

Could you tell me where did I fail? the program close when executing.
Before, it can finish the execution, but it didn't show me the results I was expecting. That's before, now it closes and didn't show me the results.
For example: if I needed the result of discount, it shows me on the results a "nan", maybe there's the problem that didn't let it finish executing.
Now, as the title says, it didn't show me results but an exit code: 255.
However, if you go to an online compiler, paste the code, execute it and follow the instructions, you will see that at the end it doesn't show the results but an exit code: 139 Segmentation fault (core dumped)
I think the problem comes mainly from SalePrice(),
Maybe I wrote it wrong or I'm missing libraries, I don't have that knowledge yet.
Sorry if I did not explain myself well, I am still learning and this had not happened to me before.
Thanks for reading untill here!

Answer 1

You've got a recursive condition that is causing your stack to overflow. Commision() calls SalePrice() which in turn calls Commision(), etc. on and on.
Refactor your functions so that they don't recursively call each other.
