   1. what's the problem with using string, well, or getline(), if there are spaces in the line? And so it turns out that after each character you need to enter a space

4. int main()
   {
   setlocale(LC_ALL, “rus”);

   int digit = 0;
   double digit2 = 0;
   char symbol = 0;
   bool trueOrFalse = 0;

   cout <> digit;
   cout <> digit2;
   cout <> symbol;
   // в переменную типа bool с помощью cin можно ввести
   // только числа 0 (интерпретируется как false) and 1 (true)
   cout <> trueOrFalse;

   cout << endl << endl;
   cout << "Целое число: " << digit << endl;
   cout << "Вещественное число: " << digit2 << endl;
   cout << "Символ: " << symbol << endl;
   cout << "bool: " << trueOrFalse << endl;

   return 0;
   }
   What am I doing wrong ?? The very first data entry works for me and then it just crashes, and I can't enter anything else. Whoever saw my mistake, please respond to my comment

   1. indicate variables with a dot, like a fraction.
