declaration

when i try to declare the following function typedef struct TRIE_NODE { char* word; struct TRIE_NODE node[26]; }TRIE_NODE; I get the following error: definition of 'struct TRIE_NODE' is not complete until the closing '}' However, if i declare this function with a pointer to the 26 nodes, it compiles just fine. typedef struct TRIE_NODE { char* word; struct TRIE_NODE* node[26]; }TRIE_NODE; I imagine that, since this is not an instance, it's impossible for me to get a pointer to the first of those 26 arrays, but if that is the problem, how is TRIE_NODE* node[26] not also a problem? Isn't this

This is a followup to C++ templates: prevent instantiation of base template I use templates to achieve function overloading without the mess of implicit type conversions: declare the function template, define desired specializations (overloads). all is well except wrong code does not produce errors until the link phase: lib.hpp: template<class T> T f(T v); lib.cpp: #include "lib.hpp" template<> long f(long v) { return -v; } template<> bool f(bool v) { return !v; } main.cpp: #include <iostream> #include "lib.hpp" int main() { std::cout << f(123L) << ", " << f(true) << ", " << f(234) << "\n" ; }

I've opened jQuery 1.7.1 library and wanted to study the code, but I've found a that functions are declared in strange way (for me). For example: show: function() { //some code here }, I learned to define function on this way: function show() { //some code here } Can someone explain me why show function is not written on second way (like in most tutorials on internet)? This is because it is within an object. Object Literals have their properties defined in this way: { name: value, //OR 'name': value } Where value can be nearly anything such as a number, string, function, or even another object

head.h #pragma once namespace foo { int bar; int funct1(); } head.cpp #include "head.h" int foo::funct1() { return bar; } main.cpp #include <iostream> #include "head.h" int main() { foo::bar = 1; std::cout << foo::funct1() << std::endl; return 0; } Error LNK2005 "int foo::bar" (?bar@foo@@3HA) already defined in head.obj I don't understand what is going on. I tried looking for the answer but everyone's questions are so specific to their code and don't even look close to the problem that I am having. I am not including .cpp files into main. I am not redefining anything. I am literally just

The following definition of declarative region : Every name is introduced in some portion of program text called a declarative region, which is the largest part of the program in which that name is valid, that is, in which that name may be used as an unqualified name to refer to the same entity. We have example into the spec below: int j = 24; int main() { int i = j, j; j = 42; } the identifier j is declared twice as a name (and used twice). The declarative region of the first j includes the entire example. The potential scope of the first j begins immediately after that j and extends to the
