C++ linked list input memory not carrying over (Maybe)

I am quite inexperienced at coding so I am not sure what is going on, but I have run my code through godbolt compiler/debugger, and it says that there is a memory leak but I don’t know how to solve this problem I do believe the issue is within the void end function though.

>Solution :

For every use of new to dynamically allocate memory, you must also use delete to deallocate that memory. You have used new but not delete so you have a memory leak.
