Why nobody offers ideone.com?
Yep, that's also legit
But I personally like more paste.ubuntu.com, but it's more to type😂

Check in your taskbar, there is likely a command prompt window open from when you were testing earlier, if there is close them

Hey everybody!
I've encountered a problem with c++. I've made myself a template class that enables me to automatically put my initialization functions into a global array and call them at certain point in lua.
The thing worked just fine, but i decided to move the array initialization to a separate file. Everything compiles fine, but when the time to call the functions comes the array is being empty. Moving the initialization back to the file with main fixes it somehow (but sometimes not, and considering the fact that this is the only thing i change)

How do you initialize it?
I mean when you call the methods that fill this array?
Pavel
I had similar problems when tried to use some static initialization tricks from Alexandresku book, and that failed in similar situations
ArrowInAKnee
It is filled by different object constructors. It's initialization allocates memory for it and sets it's capacity and amount of elements
Dima
oh, you are finally awake
Pavel
It is filled by different object constructors. It's initialization allocates memory for it and sets it's capacity and amount of elements
But these constructors called somewhere in main? These are not static objects themselves?
Pavel
Because if they are, then it sounds like static initialization fiasco

So, my initializers may be pushed before the array constructor is called?
Pavel

Yes, the order is not specified, so it can end up in any order. You moved the initialization to another file and it changed the order.
Another compiler or version of compiler, path in the file system, or moon phase can change it theoretically

Thanks a lot! I'll now try to fix it in a way that is proposed in the article. I had similar thoughts on how to do it, but this way seems much cleaner

It's rather interesting how the problem appeared only after a rather long period, cause i've already moved the things around a couple times

if i have enum and a function that is of that enum type, and returns values from that enum, can i store it like this StringorInt choice = Initial_Questionst()

i am trying to store what this function stores in a variable like so

1) this code style is unreadable
2) using goto and labels makes it unreadable af

lol goto in 2019

the function takes a user input, either I , or S, this is stored in a variable and passed in a switch statement

if its I , it returns an enum INTEGER, and if its S it return STRING

my question is more to do with storing enum values in an variable
Anonymous
it returns enum symbols

What's wrong with
MyEnum var = f();

You have typedef already

Just use int to store enum values

question is it possible to pass a function pointer to a function , but that function pointer points to a function that also takes a function pointer as a parameter
Anonymous
void create_Array(
ArrayData(*CAMAPPointer)(
StringorInt(*IQPOINTER)(void)
)
);
Anonymous
idk if this is the proper syntax, but i have a create array function which takes a function that the CAMAPPointer points to
Anonymous
that function it points to also takes a function pointer as a parameter, which i put as IQPOINTER
14•08
void create_Array(
ArrayData(*CAMAPPointer)(
StringorInt(*IQPOINTER)(void)
)
);
Is this the same as argv
