heap

问题 I have an array declaration like this: int a[]; Here a is an array of primitive int type. Where is this array stored? Is it stored on heap or stack? This is a primitve type int , all primitive types are not stored on heap. 回答1: As gurukulki said, it's stored on the heap. However, your post suggested a misunderstanding probably due to some well-intentioned person propagating the myth that "primitives always live on the stack". This is untrue. Local variables have their values on the stack, but

问题 I've read about variable arguments functions " int func(int, ...) ". Where do the arguments of these functions get allocated (stack or heap)? Because I read that the va_end() macro frees space assigned to va_list , so that word "frees" caught my eyes. Note: I know that regular functions go to stack, but this type of function is interesting as the number of arguments is not known. I just want to know for sure that it's not like arrays with no pre-defined space; we use malloc() and free() at

Just what the title says, "What is the technical definition of dynamic storage in C++?" I'm curious as to how to discuss dynamic memory allocation on the heap without making any mistakes in my explanation. 回答1: From the The C++ Programming Language: Special Edition Free store , from which memory for objects

问题 This question already has answers here : Why aren't variable-length arrays part of the C++ standard? (12 answers) Closed 10 months ago . If I have the two following statements: // OK const int ARRAYSIZE = 5; int x[ARRAYSIZE]; // NOT OK int ARRAYSIZEBAD = 5; int y[ARRAYSIZEBAD]; And I don't compile with the -pedantic-errors flag... why is the second example a bad thing? In what situation would it be preferable to use dynamic allocation with the new operator? 回答1: C++ Why are non-const array

问题 we develop an app in that you have a profil with profile picture and background image (blurred profile image) and other stuff. On all my 4 Samsung devices (S2, S3 mini, S4, S6) and on the Nexus 4 the App runs without any problems. But on the Huawei Honor 7 I get this message: OutOfMemoryError "Failed to allocate a 31806012 byte allocation with 4194304 free bytes and 24MB until OOM" The option largeHeap is set to true in the manifest. Is there any possibility to get the app to work on this

问题 In my game, I have a bitmap image which functions as the games background (drawn on a canvas). The bigger the image the more　"space" there is in the game for the user to move in, so I want the bitmap to be as big as possible without causing memory problems. Well I went overboard and drew an enormous bitmap, which caused an out of memory error immediately on initialzation, so I shrunk the bitmap a bit. But I think its too small. My question is how can I measure the "safe" limit of the memory
