The line causing the error is "int len = csv_data.at(0).size();" This is how I read the csv: vector<vector<double> > read_csv(const char *filename) { ifstream read_file(filename); vector<vector<double> > csv_data; std::string lineStr; while (getline(read_file, lineStr)) {...

At line 27,while(!read.eof())it is really not a good idea to test for eof in a while loop like this. Typically instead you would have something like while(read>>name)or perhapswhile(getline(read, line)) I still have no idea what the code at line2 20 to 25 is supposed to achiev...
In this article I try to explain why Haskell keeps being such an important language by presenting some of its most distinguishing features and detailing them with working code examples.The presentation aims to be self-contained and does not require any previous knowledge of the language. I will ...
the error is in a class in a separate .h file and is executed as a method of the object. I'm almost certain it has something to do with either the compiler thinking I am calling another getline in a different namespace or my parameters for the function are incorrect. Here is the ...
I have a question buried deep in my head for all these years, but I don't think I can hold back anymore: Why would anyone use Python or Java in Codeforces? Not everyone knows C++? I doubt so. Most coders would know at least 2 or 3 programming languages and C/C++ is one of the...

i don't know not executed conhost.exe.because i am writing a some code, the main process will be called a child console program using CreateProcess.A number of child Console program will be between 10~200. so i don't want to execute the conhost.exe with my child process....
