Answer:

Explanation:

The function floor() is used to give the integer which is smaller than or equal to the provided decimal value.

for example:

let a=5.8

floor(a);

the function provides the value 5 (smaller than or equal to 5.8).

In the given code:

variable num assigns the number 3.14.

then, floor(3.14) gives the value 3 (smaller than or equal to 3.14).

Gala2k [10]

Answer:

Following is the program in C++ Language

#include <iostream> // header file

using namespace std; // namespace std

int main() // main method

{

int n; // variable declaration

cout<<" Please enter the number :";

cin>>n; // Read the number

if(n>0) // check the condition when number is positive

{

cout<<n<<endl<<"The number is Positive"; // Display number

}

else if(n<0) // check the condition when number is Negative

{

cout<<n<<endl<<"The number is Negative";// Display number

}

else // check the condition when number is Zero

{

cout<<n<<endl<<"The number is Zero";// Display number

}

return 0;

}

Output:

Please enter the number:

The number is Positive

Explanation:

Following are the description of the program

Declared a variable "n" of int type.
Read the value of "n" by user.
Check the condition of positive number by using if block statement .If n>0 it print the number is positive.
Check the condition of negative number by using else if block statement If n<0 it print the number is negative.
Finally if both the above condition is fail it print the message " The number is Zero"

1.Write a Java program to solve the following problem using modularity. Write a method that rotates a one-dimensional array with

Westkost [7]

Answer:

Explanation:

The following code is written in Java and it asks the user for the size of the array. Then it randomly populates the array and prints it. Next, it rotates all the elements to the right by 1 and prints the new rotated array.

import java.util.ArrayList;

import java.util.Arrays;

import java.util.Random;

import java.util.Scanner;

class Brainly {

public static void main(String[] args) {

Random r = new Random();

Scanner in = new Scanner(System.in);

System.out.println("Enter Size of the Array: ");

int arraySize = in.nextInt();

ArrayList<Integer> myList = new ArrayList<>();

for (int x = 0; x < arraySize; x++) {

myList.add(r.nextInt(15));

}

System.out.println("List Before Rotation : " + Arrays.toString(myList.toArray()));

for (int i = 0; i < 1; i++) {

int temp = myList.get(myList.size()-1);

for (int j = myList.size()-1; j > 0; j--) {

myList.set(j, myList.get(j - 1));

}

myList.set(0, temp);

}

System.out.println("List After Rotation : " + Arrays.toString(myList.toArray()));

}

There is a population of owls in a forest. In one year there are 20 new owls born and 10 owls die. In this same year, 5 owls ent

Simora [160]

Answer:

The owls population increased by 13 in one year

Explanation:

The given data on the owl population are as follows;

The number of new owls born = 20 (positive increase in population)

The number of owls that die = 10 (negative decrease in population)

The number of owls that enter the forest = 5 (positive increase in population)

The number of owls that left the forest = 2 (negative decrease in population)

Let 'w' represent the number of new owls born, let 'x' represent the number of owls that die, let 'y' represent the number of owls that enter the forest and let 'z' represent the number of owls that left the forest, we get;

The change in population, ΔP = w - x + y - z

By plugging in the values, we get;

ΔP = 20 - 10 + 5 - 2 = 13

The change in the population of owls in one year is an increase in 13 owls.

Explanation: For loop is used in the C++ programming is defined as the statement that defines about the flow control .This loop works under some condition that is considered.

For loop is evaluated to execute for one time if the statement condition is true but there are also chances of no execution at all because of the incorrect condition. So, for loop might not run even once in that condition.Thus , the statement given is true.
