I understand that std::cin/std::cout are generally slower than scanf/printf, and that's primarily due to synchronization with C’s standard streams. However, all explanations I saw just say that and ...

My app first takes some input, then it 'thinks' showing a progress bar, then throws an exit code and waits with getchar() for ENTER to be clicked before exiting. The problem is that if I click ENTER ...

The scenario is: input integers and characters alternatively and read them into variables of the right type. I took the straightforward approach: read anyways as if they were all integers; when failed,...

I created a function that would take the input from the user. This is the function: int InputHandler::takeInput() { int userInput; while (true) { std::cout << " Enter 0 ...

I want to make cin>> work in QT, so it's needed to use the external terminal, not the application output. I followed all the instructions given in the previous answers about cin>> not ...

Let's limit the topic to determine whether an ESC or Up key is stroked by stardard c++. After runing stty raw in console and then combining getchar() and cin.peek() in c++, it should be ok to finish ...

I am writing a program for C++ that takes the user input with the first line containing the n integer ranging from 1-9 that informs on the grid size for the following data. then the grid with n number ...

I use CLion and if I don't have the line setvbuf(stdout, nullptr, _IONBF, 0); I don't get output in the console when debugging. But I also use: std::ios_base::sync_with_stdio(false); std::cin.tie(...

When I want to understand how to input data from the keyboard into a variable, I start by asking how cin and >> work in this context. What is the difference between them, and how are things ...

In dynamic allocation of arrays at runtime, when the array is declared before getting the array length, I encountered a behavior that could not explain. In the following code, the user provides the ...

I am using a library that has a function taking an iostream for a data stream, but I want to pass std::cin. It apparently is not possible to pass an istream to an iostream, but is there way around ...

So I am following this book Programming: Principles and Practice Using C++ 3rd edition and in section 2.3 Author gives the following code: cout << "Please enter your first name and age\n&...

The problem arises from the std::cin's weird behavior of treating std::uint8_t and std::int8_t as char-like types so it allows the input to be a character instead of a number and std::cin doesn't fail ...

I'm validating string input in C++, to make sure that the input is not empty. I know how to do it using the empty() function with getline(), but I want to know why it's not working when I use cin. ...

I'm very new to programming of any kind, so to practice, I'm trying to make a simple game where you select a dice (d4, d6, d8, etc.). Then a random number generator rolls that dice, and you have to ...
