Tasks: arithmetic operations in C ++

1. I think it's more accurate:
   #include
   using namespace std;

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

   float a, b;
   float mes1 = 0;
   float god1 = 0;
   float sum = 0;
   cout <> a;
   cout <> b;
   cout << "Проценты в месяц: ";
   mes1 = a*5/100/12;
   cout << mes1 << endl;
   cout << "Проценты в год: ";
   god1 = mes1 * 12;
   cout << good1 << endl;
   cout << "Общая сумма процентов: ";
   mes1 = mes1 * 12 * b;
   cout << mes1 << endl;
   cout << "Общая сумма выплаты: ";
   sum = a + b * good1;
   cout << sum << endl;

   cout << endl;
   return 0;
   }

2. #include
   using namespace std;

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

   float a = 0;
   // ” ‘ a ‘ – deposit amount ”
   float b = 0;
   // ” ‘ b ‘ – number of months of keeping money in the bank”
   float c = 0.05;
   // ” ‘ c ‘ – interest rate 5 %”
   float d = 365;
   // ” ‘ d ‘ – number of days per year set as a constant number”
   float e = 31;
   // ” ‘ e ‘ – the number of days in a month is set as a constant number”

   cout << "Deposit amount" <> a;

   cout << "Months" <> b;

   cout << "Profit per month" << " " << a * c / d * e << endl;

   cout << "All term profit" << " " << a *c / d * e * b << endl;

   cout << "Total amount payable after term" << " " << a + (a *c / d * e *b) << endl;

   return 0;
   }

3. int main(){
   setlocale(LC_ALL, “RUS”);

   int k;
   cout <> k;

   while (k!=0){
   cout << k % 10;
   k = k / 10;
   }
   cout << endl;

   system("pause");

   return 0;
   }

   1. Numbers with zero will not work correctly.

4. A little off task, but thought so:

   int main(){
   setlocale(LC_ALL, “RUS”);
   float sum, profit, annual = 0.05;
   int monthInYear = 12, amountMonth;
   cout <> sum;
   cout <> amountMonth;
   cout << endl << "Сумма: " << sum + (amountMonth*(sum*annual)/monthInYear) << " rub" << endl;
   system("pause");
   return 0;
   }
