I have the following class:
class clsTree;
{
private:
vector<clsNode*>m_content;
m_RootNode *clsNode;
m_LastNode *clsNode;
public:
vector<clsNode*>Content;
wstring interpret(wstring uWord);
};
The compiler does not like my member declaration of clsNode at all.
The first error I get is "Member clsTree::clsNode is not a type name.".
I don't see where I went wrong.
Can somebody help, please?
You're not showing the definition of clsNode, neither whether you have a forward declaration for it, but I'm pretty sure this:
m_RootNode *clsNode;
m_LastNode *clsNode;
Should be rewritten this way:
clsNode* m_RootNode;
clsNode* m_LastNode;

I gettin not declared in this scope error msg also declared .h file & EngineFactory class in .h
EngineFactory *engineFactory = NULL;
engineFactory = new EngineFactory();
EngineFactory->Create();
EngineFactory->destroy();
There is two problems in the code:
Your code is not inside a function. Place it in main() function, and it'll work better.
EngineFactory->Create(); has uppercase EngineFactory, while your variable is lowercase.

I am inserting 'this' pointer into a map
Does it cause a segmentation fault
My code is
client->commandHandlerMap.insert(std::pair<CommandType , CommandHandler*>(CommandType::OrderBookCommandType , this));
I am doing this inside the member function of a derived class of CommandHandler
I would assume that client is not initialized or has an invalid pointer.

Ogre::any_cast<std::map<Rail>::iterator>
It takes Ogre::any_cast<std::map<Rail> and says too few arguments etc. How can I fix it (other than obvious typedef aliasing)?
The problem is that std::map takes at least two template arguments - the key type and the value type. Currently you have std::map<Rail>. What are you mapping from Rail to? For example, this would be okay if your iterators are for a std::map that maps from Rail to int (assuming Rail is not a deduced type):
Ogre::any_cast<std::map<Rail,int>::iterator>(some_any_object)

if((kulax>=schodki[i][0][0] && kulax<=schodki[i][1]][0]) && (kulay==schodki[i][2][0]+10))
spoczywa=true;
Hi guys, I have an array of integers which name is schodki and it is declared as int schodki[5][3][1] and the global variables : int kulax and int kulay.
What's wrong in the line of code which is above ?
EDIT : Of course. "i" is the value from current state of loop.
You have an extra ] in
kulax<=schodki[i][1]][0]
which probably screws up parsing and results in a confusing error message. The compiler probably sees it as
kulax<=schodki[i][1]
which is indeed an attempt to compare an integer to a pointer. Try to pay attention to your own code and make sure it is free from primitive syntax errors before asking questions here.
Other than that, there's nothing wrong with your code (assuming that the variables are really declared the way you say they are)].

Why is it not possible to supply a default value that is defined in the parameter list for a struct? That is, why does this work
struct C {int i;};
C cc = {0};
foo(C c=cc) {}
but not
foo(C c={0}) {}
Note, I've noticed that the same holds true for arrays.
Ok, it seems this is a compiler problem with the older GCC.
