c++ - Destroy an object with variables (free memory) -

i trying create event/date organizer in c++. overview calender show 1 month , every day in calender object (type: eventcell) class eventcell stores events day in vector (name: eventdata type: "eventinfo": class storing day, name, start/endtime).

but when switch month want clear vector, destroy of objects , free memory of variables. tried this:

for (unsigned int = 0; < termindata.size(); i++) {     delete termindata[i]; } termindata.clear(); 

it calls deconstructor variables etc still alive. if make example:

termindata[0]->getday();  result: 3 

i still value of variable deleted object...

i think if don't delete gets big, because every time change month, creating object every event.

any suggestions how delete object variable etc memory , create new?

i still value of variable deleted object...

no, garbage value. accessing termindata[0] after termindata.clear(); you've invoked undefined behaviour.

any suggestions how delete object variable etc memory , create new?

you've deleted objects successfully. create new objects, construct them did originals. memory of old objects free used other objects.
