1. setlocale(LC_ALL, “rus”);
   int a, b, c,d;
   cin >> a >> b;
   cout <> d;
   if (c == d) cout << "true";
   else {
   cout << "false";
   }
   return 0;

2. #include
   using namespace std;
   int main()
   {
   setlocale(LC_ALL, “rus”);

   int a,b;
   int c;
   int summ;
   cout <> a;
   cout <> b;
   summ = a * b;
   cout <> c;

   if (c == a*b) {
   cout << "Ваш ответ: " << c << " YOU WIN!!!";
   }
   else if (c != a * b) {
   cout << "Ваш ответ: " << c << " YOU LOSE!!!"<<endl;
   cout << "Правильный ответ: " << summ;
   }

3. int A;
   cout<>A;
   int B;
   cout<>B;
   int C;
   cout<>C;
   if(A*B==C){
   cout<<"Правильно!"<<C;
   }
   else{
   cout<<"Неверно, правильный ответ\t"<<A*B<<"\n";

   // Works at random
   int main () {
   srand(time(NULL));
   int a, b;
   int answer;
   int attempAmount = 5; // Number of attempts

   attemp:
   for (int i = 0; i < attempAmount; i ) {
   a = rand() % 20; // a [0; 20]. You can change the random interval
   b = rand() % 20 – 10; // b [-10; 10]. You can change the random interval

   cout << a << " * " << b <> answer;
   if (a * b != answer) {

6. I did 1 task it turned out on 45000 lines of code, only used If, else if and operator %, this is normal? Norm that 45.000 lines of code?
   But the program works well, everything displays as it should be.

   You must write a program, which checks the user on the knowledge of the multiplication table.
   The user enters two single-digit numbers.
   The program asks the question: the result of multiplying the first day of the second.
   The user must enter a response and see on the screen is correct or not, he said,.
   If not, show the correct result as well. * /

   setlocale(LC_ALL, “rus”);

   int num1 = 0, num2 = 0, result = 0;

   cout <> result;

8. In the comment above, something was not copied, here is the correct code:

   #include
   using namespace std;

   void main()
   {
   /*
   You must write a program, which checks the user on the knowledge of the multiplication table.
   The user enters two single-digit numbers.
   The program asks the question: the result of multiplying the first day of the second.
   The user must enter a response and see on the screen is correct or not, he said,.
   If not, show the correct result as well. * /

   setlocale(LC_ALL, “rus”);

   int num1 = 0, num2 = 0, result = 0;
   cout << "Проверка знаний таблицы умножения" << endl;
   cout <> num1;
   cout <> num2;

   cout <> result;

   if (result == num1 * num2) cout << "Вы дали верный ответ\n\n\n";
   else(result == !num1 * num2),cout << "ваш ответ не верный, correct answer:", cout << num1 * num2<<endl;
