c++ - Initialize static array using lambda -


i have template in have static array. trying initialize array using lambda - think not getting initialize :

template <class base> a<base> a<base>::arr[size] = [] ()  {   (int = 0 ; < size; i++)   {     a<base>::arr[i]=a<base>();     std::cout<<"test"<<std::endl;   } };

i unable see cout message in console when run executable.

how can initialize array using lambda functionality?

you never called lambda.

the lambda not return anything, initializing return value wouldn't work anyway.

arrays cannot returned.

besides default initialization, array can initialized brace-enclosed list of values (or string literal) not can returned functions (including lambdas).

your loop appears value initialize elements. elements not listed in brace initialization list value initialized, can achieve loop empty brace enclosed list:

template <class base> a<base> a<base>::arr[size] = {};

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
