1. #include

   using namespace std;

   int main()
   {
   setlocale(LC_ALL,”RUS”);
   int a;
   cout<<"Введите четырехзначное число,I type to you in reverse order: "<>a;
   if(a>=1000&& a<=9999)
   {
   int first= a;
   int second = (a/10)%10;
   int third = (a/100)%10;
   int fourth = (a/1000)%10;

   cout<<"А это тоже число только в обратном порядке: "<<first<<second<<third<<fourth<<endl;

   }
   else{
   cout<<"Вы ввели не четырехзначное число,перезапустите программу и попробуйте еще раз.\n";

   1. you checked your code?? in line
      cout<<"Введите четырехзначное число,I type to you in reverse order: "a;
      at the end put the normal direction of the output to the screen and made variable and (removing from its pre cout) separate line cin >>a; then all zarabotatet

      1. Kirill, he has everything written correctly. This site is distorted. Try copying your code and posting it in a comment.. You'll see

2. I spent so long fiddling with the second task simply because “annual interest ”
   made it like int)))))))))))00

3. I quickly wrote it in pure C
   #include
   int main(void)
   {
   int sum, term, years, mount, a;
   float procent, result;
   do//loop to select continuation or exit
   {
   printf(“Enter sum contribution\n”);
   scanf_s(“%d”, &sum);
   printf(“Enter term contribution\n”);
   scanf_s(“%d”, &term);
   printf(“Enter interest rate\n”);
   scanf_s(“%f”, &percent);
   printf(“Enter nummber of days in year\nEnter nummber of days in mount\n”);
   scanf_s(“%d”, &years);
   scanf_s(“%d”, &mount);
   //We carry out the calculation using the formula and write the result to the result variable
   result = sum*(percent / 100) / years*mount;
   printf(“Procent per month is %.2f\n”, result);
   printf(“Per year is %.2f\n”, result * 12);
   printf(“Total is %.2f\n”, sum + (result * 12));
   printf(“Enter 1 for continue or 0 for exit\n”);
   scanf_s(“%d”, &a);
   } while (a != 0);//end of cycle
   return 0;
   }
