dictionary - Accelerated C++ header file not working -


i'm trying compile second exercise in chapter 7 written in book. created header file containing xref function:

#pragma once  #include <map> #include <string> #include <vector> #include "split.h"  std::map<std::string, std::vector<int> > xref(std::istream&, std::vector<std::string> find_words(const std::string&) = split);

afterwards wrote .cpp file:

#include "xref.h" using namespace std;  map<string, vector<int> > xref(istream& in, vector<string> find_words(const string&) = split) {     ... }

i cannot compile code, says parameter 1 not match. what's wrong?

the error message says went wrong: should specify default parameter value in function declaration, whereas did again in function definition. error refers last parameter of function.

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 <...
