C++ has no design philosophy wrt memory. All it has are two functions for allocating memory (new malloc) and two functions for freeing memory ( delete free ) and a frew related functions. Even those can be replaced by the programmer.
This is because C++ aims to run on generic computers. Generic computers are a CPU, memory (RAM, varieties of ROM) and a bus/busses for peripherals. There is no built in memory management on generic computers.
Now most computers come with memory ( typically a ROM variant ) which contains a bios/monitor. There you might see some rudimentary form of memory management --probably not.
Some computers come with OSes which will have memory management, but even there it is often primitive, and it is easy for me to claim that most computers running a C++ program have no OS at all.
If you expect C++ to run on any computer, it cannot have a memory management philosophy.
