No, I mean what is the programming problem? Telling us what you want to do does not give enough information about where you are stuck or what you have tried. If you know the mathematics of the problem then converting that into C++ code should not be too difficult.
Once again you are expecting us to guess what is happening; we cannot see your screen or read your mind. Please edit your message, add <pre> tags around your code to make it readable, and explain exactly what the problem is and where it occurs.
I wanted to calculate outgoing flux on 2D circular grid. So first part of this code is for to get grid point after that i initializes variables on those grid points, now i want to calculate diagonal to get unit normal through it .
above code running upto global time step
Hey guys, I am kind of new with C++. I have an assignment to do which is similar to this one:
My problems are how to read I/O files and how to actually DO this program. I am really lost with it.
This is not my homework, as u can see this link is from 2007. That is why I posted instead of my homework. I need assistance, so I will be able to solve my homework. If you can post something/link that may help me I will appreciate. Otherwise thank you, but I do know about my responsibilities as a student.
I have a need for creating a class template and you may help me.
 Multiple coclasses will be implemented in a single dll.
 Each coclass will implement the same interfaces but will have different class/clsid/resid.
 It is necessary to create a class template taking clsid/resid as its template paramemters.
 Finally, I need to use template classes for CoCreateInstance.
The problem is that I need to create many coclasses now and in the future.
I don't want to copy/paste for all of them because it is quite hard to maintain the source code for all the copy/paste'd coclasses. It is quite error-prone.
So, I definitely would like to create a class template.
Below, I created a class template and it compiled ok.
class ATL_NO_VTABLE CComT
: public CComObjectRootEx,
, public CComCoClass, &CLSID_T>
, public IDispatchImpl
I'm trying to compile a c++ project on a raspberry pi using g++. I get the following compilation error:
PROCESS.CPP: In function ‘int process(int, char*, ControlData*, char*, char*)’:
PROCESS.CPP:172:49: error: ‘_fullpath’ was not declared in this scope
PROCESS.CPP:185:45: error: ‘_fullpath’ was not declared in this scope
The file PROCESS.CPP has the header
which I thought should contain this declaration. I have checked the header path using the g++ -H command and it gives /usr/include/stdlib.h so I presume it is finding the file.
I don't want to start fiddling with my own declarations within the scope as there are many other files to include in this project.
