I am having trouble in initializing an array of structures with a function pointer as a member in it. class Record .c,vector,heap-memory I am creating a temporary vector of pointers to myObject objects. When initializing an object of array type, the initializer must be either a string literal (optionally enclosed in braces) or be a brace-enclosed list of initialized for array members: 1) string literal initializer for character and wide character arrays. I dont get any errors with this simplified test code: include . Struct dictnode std::string word int key int code Class LZW dictnode detable sizet desize int countdec Public: LZW() LZW() LZW::LZW() .

(items) new string[2] I couldnt find anything online that helped me. How can I initialize items or keep the array data that i made using temp. I am trying to initialize them all to NULL but I keep getting errors. Can anyone tell me what Im doing wrong?The problem is that you do not have a dynamic array of pointers. So, the straightforward way to initialize a vector with an array looks like: That is too much code for a simple initialization!This is because array pointers have all the properties required of an (input) iterator Initialize a pointer to null during declaration is a good software engineering practice. C11 introduces a new keyword called nullptr to represent null pointer.In C/C, by default, arguments are passed into functions by value (except arrays which is treated as pointers). I need an array of char defined in as a classs attribute, and initialize it with a length inside the classs constructor.Not sure about the syntaxIve only seen declaration of array of pointers with a length.
