I_Interface
this is a function i wanted to run as an default case, then i wanted it to go back to the question it orginally asked , but i think at this point the variable that stores the answer of the user input is still in the variable

Hello, I'm making an app and I have a compilator error...
I have MainView that includes SecondUI and PackageView but PackageView and SecondUI includes MainView and I get this error:
"MainView is not declared in this scope" when I put the following function in SecondUI and PackageView :
public Q_SLOTS:
void setParenting(MainView *);
can some one help me to fix it?
N.B.: I added " class -{class name}- ; " in every header, separated of the " class -{class name}- : public -{class name}- { ... };

Hello. I'm beginner in C++. Please I need to use a vector of references, but I don't know the correct declaration
I tried
std::vector <struct Filleul& > listeFilleul;
But it seems to have an error !

You don't need to use struct keyword in this context

You don't need to use struct keyword in this context
Here, I want to use a vector of references to struct data type :
struct Filleul
{
int idFilleul;
std::string nomFilleul;
bool aUnParrain = false;
};
struct Parrain
{
int idParrain;
std::string nomParrain;
std::vector <struct Filleul& > listeFilleul;
};

Can you help too? 😥
Have it... I had to use the forward declaration but never used it, I declared as forward the class that is in the header...
I had to use in class SecondUI and PackageView:
class MainView;
and not
class {class name, the name of the class dedicated to this file};

struct is used to create new types

But itself it's just a keyword

Which can be used not only for creating types

How to undef a typedef, For example, Ms define a struct in "wininternl.h" which like
typedef enum _PROCESSINFOCLASS {
ProcessBasicInformation = 0,
ProcessDebugPort = 7,
ProcessWow64Information = 26,
ProcessImageFileName = 27,
ProcessBreakOnTermination = 29
} PROCESSINFOCLASS;
and I include the header, but, the enum is not my dish. I wanna redefine the enum like
typedef enum _PROCESSINFOCLASS
{
ProcessBasicInformation,
ProcessQuotaLimits,
ProcessIoCounters,
ProcessVmCounters,
ProcessTimes,
ProcessBasePriority,
ProcessRaisePriority,
ProcessDebugPort,
ProcessExceptionPort,
ProcessAccessToken,
...
}
how to achive that. is there a method like #undef ???

You can't have a vector of references, you can you reference_wrapper

I tried to index a rel. small and simple C++ project using BOOST, it failed to "digest" the boost itself, do you have some tips to make boost "parsable" ?
Do you add boost path to Header Files & Directories to Index in your sourcetrail project?

there must be some defines for tuning BOOST for a specific compiler, VC in my case.
It seems they are missing.

I still love the goto label; // sue me of Alexandrescu

Also, well, sometimes goto is just the way to avoid cache issues

I just download boost binary for msvc14.2 and install it. After that, I create a new project and
add boost path to Project Property/VC++ Directories/Include Directories
and
add lib64-msvc-14.2 to Project Property/Linker/General/Additional Library Directories.
After updating the settings, I can compile my simple code with boost.
To use source trail, I opened this simple project by MSVC and create a new project of source trail by following steps.
1. Select C/C++ from Visual Studio as the source group.
2. Click Create Compliation Database.
3. Switch to MSVC and a windows will pop up.
4. Select the project you want to parse and click Create.
5. A Cbd Ready window pops up and click Import.
6. Switch back to new source group window of source trail and click Select from Compilation Database at Header Files & Directories to Index section.
7. Select boost path and your project path then click Save,
8. Click Next.
9. Click Create
10. You can start parsing your project.

Actually this is a very big question because this depends on what Qt version you use in the application.
It is one thing if you use system Qt, and another if you use latest or specific Qt version

Hi! I have a question about multiple global definition. I have two files:
foo5.c
#include <stdio.h>
void f(void);
int x = 15213;
int y = 15212;
int main()
{
f();
printf("x = 0x%x y = 0x%x \n", x, y);
return 0;
}
and bar5.c
double x;
void f()
{
x = -0.0;
}
the result of work:
gcc -o foobar5 foo5.c bar5.c && ./foobar5
x = 0x0 y = 0x80000000
I can't uderstand why y contains 0x80000000? After all, bar5.c does not define y and does not change its value. I expected the variable x to be changed in the foobar5.
Anonymous
Oh, I get it. The assignment x = -0.0 will overwrite the memory locations for x and y

hello somebody know how works std::reduce?
Anonymous
I have an issue with this, std::vector of 3dpoint(x,y,z) gives me overflow
Ludovic 'Archivist'
hello somebody know how works std::reduce?
Kinda exactly like std::accumulate, but expect the reduction to be commutative
Anonymous
3dpoint = std::reduce(vector.begin(), vector.end());
