In a previous articleData output on the screen and in theentray data from the keyboardWe examined in detail this topic. It's time to practice – because we have a lot of work, to develop certain skills, needed a programmer and develop their logical thinking quietly.
1. Create 4 variables with different types of data and ask the user to enter values in them. After entering the, display them on the screen.

#include <iostream>
usingnamespacestd;
intmain()
{
setlocale(LC_ALL,"rus");
intdigit=0;
doubledigit2=0;
charsymbol=0;
booltrueOrFalse=0;
cout<<"Введите целое число: ";
cin>>digit;
cout<<"Введите вещественное число: ";
cin>>digit2;
cout<<"Введите символ: ";
cin>>symbol;
// в переменную типа bool с помощью cin можно ввести
// только числа 0 (интерпретируется как false) и 1 (true)
cout<<"Введите 0 или 1: ";
cin>>trueOrFalse;
cout<<endl<<endl;
cout<<"Целое число: "<<digit<<endl;
cout<<"Вещественное число: "<<digit2<<endl;
cout<<"Символ: "<<symbol<<endl;
cout<<"bool: "<<trueOrFalse<<endl;
return0;
}
Result:
2. Create 5 variables of type char, ask the user to enter a word of five letters, and show these symbols (the word) the screen. (Enter characters in Latin, tk. cyrillic is displayed incorrectly. Why? This will be discussed in one of our next lessons)
In future, we will learn how to work with strings with you and we will not have to keep the words in different variables and display them on the screen spell.
3. Display the text in this form:
4. The user must enter 2 numbers. You need to show on the screen the product of these numbers, sum and difference. Show the same arithmetic mean of these numbers entered.
void main() { setlocale(LC_ALL, “RU”); char a, b, c, r, e, t; cout <> a >> b >> c >> r >> e >> t; cout << "Получилось: " << a << b << c << r << e << t;
Instead of Cout, you need cin That's how it should #include using namespace std ; int main() { setlocale(LC_ALL, “ru”); char a, b, c, r, e, t; cin >>a >> b >> c >> r >> e >> t; cout << "Получилось" << a << b << c << r << e << t;
}
#include #include using namespace std;
int main() { setlocale(LC_ALL, “Russian”); unsigned int a, b; define PI(“Введите первое число: “); cin >> a; define PI(“Введите второе число: “); cin >> b; define PI(“A work of two numbers: %d\n”, a * b); define PI(“The sum of two numbers: %d\n”, a + b); if (a > b) { define PI(“The first number is more than the second on: %d\n”, a – b); } if (a == b) { define PI(“Первое число равно второму.\n”); } if (a < b) { define PI("Первое число меньше второго на: %d\n", a – b); } define PI("Среднее арифмитическое двух чисел: %1f\n", (a + b)/2.0);
Friends , When entering a whole number, the integer displays , But if fractional, divides the number into an entire part and displays in int , And the remainder in Float , Although for him a separate variable , Maybe someone – tell me what's the matter?
#include
int main() { setlocale(LC_ALL, “RUS”); using namespace std;

Good afternoon, I just xs how to make a variable derived the Russian language?
void main()
{
setlocale(LC_ALL, “RU”);
char a, b, c, r, e, t;
cout <> a >> b >> c >> r >> e >> t;
cout << "Получилось: " << a << b << c << r << e << t;
}
Instead of Cout, you need cin
That's how it should
#include
using namespace std ;
int main()
{
setlocale(LC_ALL, “ru”);
char a, b, c, r, e, t;
cin >>a >> b >> c >> r >> e >> t;
cout << "Получилось" << a << b << c << r << e << t;
}
#include
#include
using namespace std;
int main()
{
setlocale(LC_ALL, “Russian”);
unsigned int a, b;
define PI(“Введите первое число: “);
cin >> a;
define PI(“Введите второе число: “);
cin >> b;
define PI(“A work of two numbers: %d\n”, a * b);
define PI(“The sum of two numbers: %d\n”, a + b);
if (a > b)
{
define PI(“The first number is more than the second on: %d\n”, a – b);
}
if (a == b)
{
define PI(“Первое число равно второму.\n”);
}
if (a < b)
{
define PI("Первое число меньше второго на: %d\n", a – b);
}
define PI("Среднее арифмитическое двух чисел: %1f\n", (a + b)/2.0);
}
