dynamic memory

Question

how we allocate dynamic memory ?

Answer 1

hinanawi It's not considered good practice to manually allocate and deallocate memory with those functions. C++ best practice to use smart pointers like unique_ptr and shared_ptr

Answer 2

malloc/free/realloc in C++ must be used ONLY for raw memory allocation while for objects you have to use new/delete

Answer 3

for memory manipulation you would use malloc(), realloc(), and free(), if that's your question.

Answer 4

ok thanks
