I need to create a method named "root positive". which will either print the square root of the number passed to it or if the nu

mber is less than zero, it will print out the statement "Number must not be negative."?
1. Ask the user to input a number of type double which you will find the square root of the number.

2. Create a method called rootPositive which will either print the square root of the number passed to it or if the number is less than zero, it will print out the statement "Number must not be negative.".

3. Call your rootPositive method and pass to it the number the user enetered.

Answer:

Explanation:

The following code is written in Java. It is a method that calculates the square root of a number as requested. The method first checks with an IF statement if the parameter value is a positive number and then calculates the square root and prints it to the screen. Otherwise, it prints Number must not be negative. A test case has been provided in the main method and the output can be seen in the attached image below.

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.print("Enter a number of type double to calculate square root:");

       double num = in.nextDouble();

       rootPositive(num);

   }

   public static void rootPositive(double num) {

       if (num > 0) {

           System.out.println(Math.sqrt(num));

       } else {

           System.out.println("Number must not be negative.");

       }

   }

}

Which of the following function declarations correctly expect an array as the first argument?
NARA [144]

Answer:

Only

Option: void f1(float array[], int size);

is valid.

Explanation:

To pass an array as argument in a function, the syntax should be as follows:

functionName (type arrayName[ ] )

We can't place the size of the array inside the array bracket (arrayName[100]) as this will give a syntax error. The empty bracket [] is required to tell the program that the value that passed as the argument is an array and differentiate it from other type of value.
