• Im having trouble with this assignment that has me write vectors and arrays to a file

  So in this assignment I have to have one function that has the user enter the vector which is the driver name and then they enter the drivers 4 points. That function is fine. I also Have to do a second function that writes the name and the average that I get from the 4 points to the txt file. and then display the name and averages in main. Right now I am stuck on the second function because I'm having trouble getting it to where it would write the vector and then the average after it. right now it is writing both vector elements and then the first average, and then both vector elements and the second average. can someone help me

• Attempting to solve this problem more efficiently

  I read a natural number with at most 9 digits. I have to form a vector with the even digits of that number, in ascending order, with each digit appearing once (example : 98762222 is going to output: 2 6 8). I want to know what optimisations can I add to this code to make it more efficient.

  #include <iostream>
  
  using namespace std;
  
  int main()
  {   int x,i,k=0,copy,v[10]={0},j;
      cout<<"x=";
      cin>>x;
      copy=x;
      if (x==0)
          cout<<0;
      while (x>0)
      {
          v[x%10]++;
          x/=10;
      }
      for (i=0; i<10; i=i+2)
      {
          if(v[i]>0)
          {
            k++;
          }
      }
      int w[k]={0};
      if (k>0)
       {  j=0;
          for (i=0; i<10; i=i+2)
            if(v[i]>0)
             {   w[j]=i;
                 j++;}
       }
  
      for (j=0; j<k; j++)
          cout<<w[j]<<" ";
      if (k==0 && copy!=0)
       cout<<"No even digits";

• Receiving error: "error: static assertion failed: result type must be constructible from value type of input range" when constructing class vectors

  I am trying to create a script that uses polymorphism to create a set of linking vectors within parent/child class structure. So far I have got the classes setup, but when trying to test the code I receive an error involving static assertion. When analysing the code line by line, I run into the error when I call 'vector.begin() & vector.end()'.

  Here is the full script:

  #include <iostream>
  #include <vector>
  using namespace std;
  
  class A
  {
  public:
      vector<vector<A *>> Container;
  };
  
  class B : A
  {
  };
  
  class C : A
  {
  };
  
  class D : A
  {
  };
  
  int main()
  {
      A ABaseClass;
  
      B b1, b2;
      C c1, c2;
      D d1, d2;
  
      vector<B *> b_classes = {&b1, &b2};
      vector<C *> c_classes = {&c1, &c2};
      vector<D *> d_classes = {&d1, &d2};
  
      ABaseClass.Container = {
          {b_classes.begin(), b_classes.end()},
          {c_classes.begin(), c_classes.end()},
          {d_classes.begin(), d_classes.end()}};
  }
  

  Compiling gives this error:

  error: static assertion failed: result type must be constructible from value type of input range
    138 |       static_assert(is_constructible<_ValueType2, decltype(*__first)>::value,
        |                                                                        ^~~~~
  
  error: static assertion failed: result type must be constructible from value type of input range
  note: 'std::integral_constant<bool, false>::value' evaluates to false
  

  I have narrowed down the cause of the error to this section:

  ABaseClass.Container = {
          {b_classes.begin(), b_classes.end()},
          {c_classes.begin(), c_classes.end()},
          {d_classes.begin(), d_classes.end()}};
  

  Following the root of the problem leads me to the file 'stl_uninitialized.h', and the line:

  [138]      static_assert(is_constructible<_ValueType2, decltype(*__first)>::value,
                                                                              ^~~~~
  

  I have been trying to get the child classes to be tracked by the parents but I am unfamiliar with vectors and pointers so I am a bit stuck. Any help with moving forward would be greatly appreciated.
• Software connected to LAN on XP, but not on Windows 10

  I recently upgraded my operating system from windows XP SP3 to windows 10pro.

  The problem is that I have a software that worked perfectly under XP, but which, once installed on Windows 10, cannot exchange data with other devices on the LAN network.

  With the same network configurations as under XP, the software does not even connect to the LAN network.

  However, the ping towards all the IP addresses of the network shows that everything is fine. But still, the software is not connected.

  On other forums I have been told about certain security updates under windows 10 which could be the cause of this communication failure.

  Is that the case ? If so, what would be the best solution to my problem please?
• Getting around a VPN

  I work at a very large company that requires a VPN at all times unless you are connected to their internet which is extremely common I know. There is one issue that this VPN causes that makes my job alot more work. For my job I have to connect to devices via ethernet to communicate with them kind of like a raspberry pi. But the issue is the VPN takes any ethernet connection as a internet connection and tries to encrypt it but obviously it fails because it's never able to connect to the VPN server because that ethernet connection doesn't connect to the world wide web. So it forces me to either use the internet or have a connection to one of the devices but never both unless I'm on my company's internet which almost never happens as I'm usually at many different buildings. My colleges and I have only been able to find one way around this and that was by using a virtual machine to forward the ethernet connection but this solution is extremely lengthy and a pain to use as the you need to boot into a vm everytime. Does anyone know of a solution to a problem like this? Is there a way to trick the vpn into not encrypting certain connections? Let me know what you guys know.
• Can you cut an ethernet cable and use led and light resistor to make it Lifi?

  I have been researching LiFi, it is a very new technology using LEDs and Light Resistors to send and receive data, however, I can't seem to find supported libraries in Python and all protocols have to be custom. So I had an idea, what if I cut an ethernet cable, and put led on the end of it, so it turns on and off as the data gets sent and an LDR on the other end to receive the said Data? is this theoretically possible?
• How to enable resource dictionary diagnostics in WPF?

  I'm tracking an instance of non-existing resource in WPF. What I'm given is an InvalidOperationException informing, that UnsetValue is not a proper value for Background property. However, I don't know, what is the missing resource key or where this setter resides.

  I see in WPF sources, that StaticResource markup extension uses an internal WPF class called ResourceDictionaryDiagnostics to log events regarding resource lookup (see eg. lines 137,152).

  Is there a way to enable this diagnostic and capture some information about failed resource lookups?
• Fixed effect instrumental variable (IV) regression with available diagnostic tests

  May I please know an R package and code to run fixed effect instrumental variable (IV) regression with available diagnostic tests (e.g., weak instrument test, exogeneity test (using Wu-Hausman), Sargan test)?

  I know plm code provides the fixed effect IV regressions but its diagnostic tests are not available unfortunately.

  Even if I run the iv_robust code from estimatr package and specify as diagnostics = TRUE, it produces a warning message saying

  "In iv_robust(.. : Will not return diagnostics if fixed_effects are used."

  So no diagnostics can be run in fixed effect using iv_robust code either.

  I also have both x and x^2 endogenous variables. I wonder what is the best way to run the fixed effect IV regression and how to do the diagnostic tests for these as well.
• CAPL function to add a delay

  I am using CAPL to control the power supply. I need to add a delay in my script, since I am not using the test node testwaitfortimeout() function can't be used. I tried giving the delay using while loop and timer function, but this crashes CANoe. Is there is any other way to add a delay?
• Compilation errors in VTest studio script while importing configuration

  While importing a new CANoe configuration the VTest studio script is showing errors. Rectifying it is time consuming.Is there any solution? What might be the reason. The same script works perfectly in old configuration.
