— Sorry for my question, I want to open a file and write on with C++, but the file is in a folder protected by password, any ideas?
Well, I guess you should run the software that protected that folder in the first place. Otherwise, I don't think there's a way to do it
— One question
— Try googling
— If i have on a derived class a pointer should i create
— Destructor where i delete the pointer
— Assign pointer to null
— Your question seems unclear to me
— So i have a main class and a subclass , in each class i have 2 sifferent pointers , i create a destructor for main class , should i create a destructor for subclass ?
— Where i delete the pointer from derived?
— Guys plz help me. I don't understand why my program crashes
