Question

Write a complete program that declares an integer variable

Answer 1

Answer:

Java:

import java.util.Scanner;

public class Main {

 public static void main(String[] args) {

   Scanner sc = new Scanner(System.in);

   int number = sc.nextInt();

   System.out.println(number + " " + number*2 + " " + number**2);

 }

}

Python:

num = int(input("Number: "))

print(num+" "+num*2+" "+num**2)

C++:

#include <iostream>

int main() {

 int number;

 std::cin >> number;

 std::cout << num << " " << num*2 << " " << num**2;

 return 0;

}
