I am currently implementing a scheduler for which I need more information on each frame than the message and its standard headers carry. I created an Object containing all the information and now I want to add a pointer to a .msg file pointing to the informatino object. The .msg File is used to tag the information to the frame later on.

For this I have created a new message file.

So I had this question at an exam. And I don't know which answer is correct.

The "Template non-type arguments" paragraph of the article „Template parameters and template arguments“ states:

The only exceptions are that non-type template parameters of reference or pointer type and non-static data members of reference or pointer type in a non-type template parameter of class type and its subobjects (since C++20) cannot refer to/be the address of

• a temporary object (including one created during reference initialization);
• a string literal;
• the result of typeid;
• the predefined variable __func__;
• or a subobject (including non-static class member, base subobject, or array element) of one of the above (since C++20).

Emphasis is mine.

And below there is an example

When I try this

I wonder to know how I can compare date and time in a string format in C++? In other words my question is that how can I implement the compare function for the following class using libraries?

When I install codeblocks, there was an option about set this program for all c/c++ files and after that all file with .cpp, .C, .cxx, .cc extensions was associated to open with codeblocks as its default program. But, then I reinstall codeblocks then that options didnt come and I need to associate all cplusplus/c files to open with codeblocks as its default program. But why do I need this?

Operating system: windows 7 32 bit

I the 32 bit version of codeblocks with mingw compiler and the the version was 20.3. But why is tjis happening? And if it's not the right place to ask this question then plz tell me where to ask?

This is my first question here, I hope that It doesn't sound stupid. So I'm trying to find a way to get the index of the first character from a string that matches the regular expression. I made my research in the regex reference in cplusplus.com but I wasn't able to find anything (probably my fault). For anyone that still don't understand what I want to do, let's make a small example, I have the following code:

What does this mean? The following is a snippet from here

I am using SWIG to create python wrappers for a C++ library. The library has a few public std::vector member variables that I would like to use as lists in python. However, I haven't been able to found a solution that works. Below is a simplified example which illustrates my current solution:
