2. int main() {
   setlocale(0, “”);

   int visitors;
   int age;
   int min_age = 999;
   int max_age = 0;
   int average_age = 0;
   int time;
   double money_per_hour = 0;
   int general_money = 0;

   std::cout << "Введите стоимость одного часа занятий в спортзале" <> money_per_hour;
   std::cout << "Введите кол-во посетителей" <> visitors;

   for (int i = 0; i < visitors; i ) {
   std::cout << "Введите возраст посетителя №" << i + 1 <> age;
   if (age max_age) {
   max_age = age;
   }
   average_age = (average_age + age) ;
   }
   for (int i = 0; i < visitors; i ) {
   std::cout << "Введите время проведенное в зале посетителем №" << i + 1 <> time;
   general_money = general_money + time * money_per_hour;
   }
   std::cout << "Минимальный возраст посетителя – " << min_age << ", and the maximum – " << max_age << std::endl;
   std::cout << "Средний возраст равен " << average_age / visitors << std::endl;
   std::cout << "Общий доход за день составляет " << general_money << std::endl;
   return 0;

3. A task 1 через do while

   #include
   using namespace std;

   int main()
   {
   setlocale(LC_ALL, “Russian”);

   int num1{ 0 };
   char p = 'y';

   do
   { cout <> num1;
   cin.ignore(32767, ‘n’);
   cout << "Квадрат числа " << num1 << " is " << num1*num1;
   cout <> p;
   } while (p == ‘y’ || p == ‘Y’);

   cin.get();
   return 0;
   }

4. #include
   using namespace std;

   int main()

   int number = 1;;
   for (;;) {
   if (number == 1) {
   cout <> number;
   cout << "Квадрат числа " << number << " is: ";
   number = number * number;
   cout << number << "\nХотите продолжить? (1 – to continue, any other number – to stop." <> number;
   if (number >= 2 || number < 0) {
   break;
   }
   }
   }
   return 0;

5. This is the kind of shit I did)
   #include
   #include
   using namespace std;

   int main()
   {
   setlocale(LC_ALL, “russian”);
   int i;
   int ch;
   cout <> i;
   for (;;) // запуск бесконечного цикла
   {
   cout << "Число, squared : " << pow(i, 2) << endl;
   if (i == i++ and i == i–)
   break;
   }
   for (;;) {
   cout <> ch;
   if (ch > 0)
   break;
   if (ch == 0) {
   cout << "Здорово, let's continue!" << endl;
   for (;;) // запуск бесконечного цикла
   {
   cout <> i;
   cout << "Число, squared : " << pow(i, 2) < 0) {
   cout << "Охуенно, till!";
   }
   }
