SOLUTION

real numbers

Algorithm analysis

In this problem, you need to read three real numbers, compute and print their sum and product.

Algorithm realization

Read three real numbers.

scanf("%lf %lf %lf", &a, &b, &c);

Compute and print the sum and the product of three numbers.

s = a + b + c;

p = a * b * c;

printf("%.4lf %.4lf\n", s, p);

Java realization

import java.util.Scanner;

class Main

{

public static void main(String[] args)

{

Scanner con = new Scanner(System.in);

double a = con.nextDouble();

double b = con.nextDouble();

double c = con.nextDouble();

double s = a + b + c;

double p = a * b * c;

System.out.printf("%.4f %.4f",s,p);

con.close();

}

}

Python realization

Read three real numbers.

a, b, c = map(float, input().split())

Compute and print the sum and the product of three numbers.

print(a + b + c, a * b * c)
