Consider this classic example used to explain what not to do with forward declarations: //in Handle.h file
I have allocated and array of Objects Objects *array = new Objects[N]; How should I delete this array? Just
Is it true that the following yields undefined behavior: void * something = NULL; char * buffer = new char[10];
I\'m a bit confused about handling an array of objects in C++, as I can\'t seem to find information about how they are passed around (reference or value) and how they are stored in an array.
When you allocate an array using new [], why can\'t you find out开发者_运维技巧 the size of that array from the pointer? It must be known at run time, otherwise delete [] wouldn\'t know how much memor
Wha开发者_如何学Ct is the difference between delete and delete[] operators in C++?The delete operator deallocates memory and calls the destructor for a single object created with new.
I have a pointer to a map that I am trying to delete (this map was allocated with new). This map is valid I think, when I hover on it while debugging, it shows pMap: [0]() ..
I would like to know how to adapt section 11.14 of the C++-FAQ-lite to arrays. Basically, I would want something like this:
After I do, say Foo* array = new Foo[N]; I\'ve always deleted it this way delete[] array; However, sometimes I\'ve seen it this way:
IP_ADAPTER_INFO *ptr=new IP_ADAPTER_INFO[100]; if I free using delete ptr; will it lead to memory leak, if not then why ?
