C++ pointer to a pointer to an array consisting of n elements -


c++ how initialize pointer:

int (**alines)[2] ?

i'm trying initialize:

int (**alines)[2] = (int(**)[2]) new int*[10]; for(int = 0; < 10; i++){     alines[i] = new int[5][2]; }

in c++, vector should default choice of container. naked new's should avoided well. avoid dynamically allocating objects unless necessary. following these guidelines result in code safer , easier maintain.

here's how make vector of ints, pointer said vector, , pointer said pointer.

std::vector<int> v = {3,8,1,6}; std::vector<int>* p = &v; std::vector<int>** pp = &p;  std::cout << p->front() << std::endl;  std::cout << (*pp)->back() << std::endl;

i'm not sure you're trying in code have shown, there's better way. if describe you're trying achieve can more.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
