Shared pointer use count after reset
Refer code below: https://www.sololearn.com/compiler-playground/c8i3yyr0wNWx You should mainly focus on last few lines of main function. Initially, spIT2.use_count() results into 2 (one is object itself and other count is added due to AddReportee). This 2 seems correct to me. Once I do spIT2.reset(); , doesn't it mean it reduces only 1 reference? Why subsequent use_count shows 0 instead of 1? https://code.sololearn.com/c8i3yyr0wNWx/?ref=app

after spIT2.reset();, spIT2 is empty (i.e. does not point to any object).
according to the standard:
"
"std::share_ptr::use_count" returns 0 when *this is empty.
"

Thanks for this. It helped me understand it in bit more details.
I have another question posted as below:

Would be great if you can share your thoughts.
By the way, many thanks again for your help.
