Tasks: arithmetic operations in C ++

If you have already read the articleArithmetic operations in C ++ you can begin to practice.

1. Common task: Given the four-digit number (for example 5678), display the numbers in reverse order of which is the number of member. That is, we should see on the screen 8765. Tip: to take from among the individual numbers, should be applied to the modulo 10.

2. The site of almost any commercial bank, you can find the so-called Deposit calculator, which allows people to, not wishing to go into the formula for calculating interest rates, to know how much they will receive. To do this, they just fill in certain fields, press the button and see the result. This is a simple program, which has already been able to write each one of you. So, a task: The user enters the amount of the deposit and the number of months of keeping money in the bank. It is necessary to calculate and show the screen profit from the deposit in a month, for the entire term of the deposit, and the total amount payable at the end of the period. Currency let it be – U.S. dollar. Interest rate – 5% APR. The formula for calculating percent per month– SumDeposit * (interest rate / 100) / daysperyear * dayspermonths.

#include <iostream>
using namespace std;

int main()
{
setlocale(LC_ALL, "rus");

float sumDeposit = 0; // сумма депозита
int amountMonth = 0; // количество месяцев
float profit = 0; // прибыль
float annualRate = 5; // пять процентов годовых
int daysInYear = 365;
int daysInMonth = 30;

cout << "Введите сумму депозита в долларах: ";
	cin >> sumDeposit;
cout << "Введите количество месяцев: ";
	cin >> amountMonth;

cout << "\nРасчет\n";
cout << "=======================================\n";
cout << "Проценты в месяц: ";
// проводим расчет по формуле и записываем в переменную profit
profit = sumDeposit * (annualRate / 100)  / daysInYear * daysInMonth;

cout << sumDeposit << " * " << annualRate << "%  / " << daysInYear
	 << " * " << daysInMonth << " = " << profit << " $" << endl;

cout << "Проценты за весь срок: ";
// умножаем % за 1 месяц на весь срок депозита и записываем в profit
profit *= amountMonth;
cout << profit << " $"  << endl;

cout << "Общая сумма выплаты в конце срока: "
	 << sumDeposit + profit  << " $";
cout << endl << endl;

return 0;
}

#include <iostream>

using namespace std;

int main()

{

setlocale(LC_ALL, "rus");

float sumDeposit = 0; // сумма депозита

int amountMonth = 0; // количество месяцев

float profit = 0; // прибыль

float annualRate = 5; // пять процентов годовых

int daysInYear = 365;

int daysInMonth = 30;

cout << "Введите сумму депозита в долларах: ";

cin >> sumDeposit;

cout << "Введите количество месяцев: ";

cin >> amountMonth;

cout << "\nРасчет\n";

cout << "=======================================\n";

cout << "Проценты в месяц: ";

// проводим расчет по формуле и записываем в переменную profit

profit = sumDeposit * (annualRate / 100) / daysInYear * daysInMonth;

cout << sumDeposit << " * " << annualRate << "% / " << daysInYear

<< " * " << daysInMonth << " = " << profit << " $" << endl;

cout << "Проценты за весь срок: ";

// умножаем % за 1 месяц на весь срок депозита и записываем в profit

profit *= amountMonth;

cout << profit << " $" << endl;

cout << "Общая сумма выплаты в конце срока: "

<< sumDeposit + profit << " $";

cout << endl << endl;

return 0;

solved the second problem… I decided to bother with it some more.)

why do all the percentages come out = 0?

#include
int main()
{
int i = 5678;
int a = i % 567;
int b = ((I % 56)-8)/10;
int c = ((I % 5000)-78)/100;
int d = (i-678)/1000;
int igf = (a * 1000) + (b * 100) + (c * 10) + d;
std::cout << "igf=" << "/t" << igf << endl;
return o;
}
Rational?

1 the task is solved much easier:
#include
using namespace std;
void main()
{
setlocale(LC_ALL, “rus”);
int a=0;
cout<>a;
cout<<"Ваше число: "<<a<<a/10<<a/100<<a/1000;
}

Help! Why is monthly interest not calculated?? With this program code
#include
using namespace std;
int main()
{
setlocale(LC_ALL, “rus”);
long summa_depozita;
cout <> summa_deposita;
int kolichestvo_mesyacev;
cout <> kolichestvo_mesyacev;
cout << endl;
const int stavka = 5;
cout << "Процентная ставка – " << item << "% годовых" << endl;
const int day_v_godu = 365;
cout << "Дней в году – " << day_v_godu <<" дней"<< endl;
int day_v_monthyace;
cout <> dney_v_mesyace;
cout << "Будет начисленно – " << deposit_summa*(item / 100) / (dney_v_godu*dney_v_mesyace) << " % per month" << endl;
return 0;
}

I did this first:
C++
#include using namespace std; int main() { int a; cout <> a; cout << a%10 << a/10%10 << a/100%10 << a/1000 << endl; return 0; }
1
2
3
4
5
6
7
8
9
10
#include
using namespace std;

int main()
{
    int a;
    cout <> a;
    cout << a%10 << a/10%10 << a/100%10 << a/1000 << endl;
    return 0;
}
