How to write a program that prompts the user to input two POSITIVE numbers — a dividend (numerator) and a divisor (denominator).

fomenos

Answer:

num1 = int(input("Numerator: "))

num2 = int(input("Denominator: "))

if num1 < 1 or num2<1:

print("Input must be greater than 1")

else:

print("Quotient: "+str(num1//num2))

print("Remainder: "+str(num1%num2))

Explanation

The next two lines prompts the user for two numbers

num1 = int(input("Numerator: "))

num2 = int(input("Denominator: "))

The following if statement checks if one or both of the inputs is not positive

if num1 < 1 or num2<1:

print("Input must be greater than 1")-> If yes, the print statement is executed

If otherwise, the quotient and remainder is printed

else:

print("Quotient: "+str(num1//num2))

print("Remainder: "+str(num1%num2))

File Sales.java contains a Java program that prompts for and reads in the sales for each of 5 salespeople in a company. It then

myrzilka [38]

Answer:

import java.util.Scanner;

public class Sales

{

public static void main(String[] args) {

int sum;

Scanner input = new Scanner(System.in);

System.out.print("Enter number of salespeople: ");

int salespeople = input.nextInt();

int[] sales = new int[salespeople];

for (int i=0; i<sales.length; i++)

{

System.out.print("Enter sales for salesperson " + (i+1) + ": ");

sales[i] = input.nextInt();

}

System.out.println("\nSalesperson Sales");

System.out.println("--------------------");

sum = 0;

int maxSale = sales[0];

int minSale = sales[0];

int minId=1;

int maxId=1;

for (int i=0; i<sales.length; i++)

{

System.out.println(" " + (i+1) + " " + sales[i]);

sum += sales[i];

if(maxSale < sales[i])

{

maxSale = sales[i];

maxId = i+1;

}

if(minSale > sales[i])

{

minSale = sales[i];

minId = i+1;

}

System.out.println("Total sales: " + sum);

System.out.println("The average sale is: " + sum / salespeople );

System.out.println("Salesperson "+ maxId + " had the highest sale with "+ maxSale + ".");

System.out.println("Salesperson "+ minId + " had the lowest sale with "+ minSale + ".");

int amount = 0;

int counter = 0;

System.out.print("Enter an amount: ");

amount = input.nextInt();

for (int i=0; i<sales.length; i++)

{

if(sales[i] > amount) {

counter++;

System.out.println("Salesperson "+ (i+1) + " exceeded given amount. (Number of sales: " + sales[i] +")");

}

System.out.println("Number of salespeople exceeded given amount is: "+ counter);

}

Explanation:

- Ask the user for the number of salesperson

- According to entered number, create an array called sales to hold sale number for each person

- In the first for loop, assign the given sales numbers

- In the second for loop, print all the sales people with sales, calculate the total sales. Also, find the minimum and maximum sales numbers with associated individuals.

- Print total, average, highest, and lowest sales.

- Ask user enter an amount

- In the third for loop, find the sales people who exceeded this amount.

- Print number of sales people who exceeded the amount.

A security system uses sensors at every door and window which will set off an alarm if any one of them is opened. There is also

jeka57 [31]

Well think of it like this lets say this wasn't and security system and it was a video game console and remote.
Now the console or keypad or the main components the power on or shut off the devices and the remote or sensors are the secondary parts but they are needed to help the console or keypad figure out what they are doing.

On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * rn, where n is the distance

Stels [109]

Answer:

#include <stdio.h>

int main()

{

float your_value1, your_value2, your_value3, your_value4, your_value5;

printf("Enter a frequency: ");

scanf_s("%f", &your_value1);//storing initial key frequency in your value 1

float r = 2.0 / 12;//typing 2.0 so it is treated as float and not int

your_value2 = your_value1 * r * 1; //initial*r*n

your_value3 = your_value1 * r * 2; //initial*r*n

your_value4 = your_value1 * r * 3; //initial*r*n

your_value5 = your_value1 * r * 4; //initial*r*n

printf("%0.2f %0.2f %0.2f %0.2f %0.2f", your_value1, your_value2, your_value3, your_value4, your_value5);

return 0;

}

Explanation:

The purpose of this exercise is to make you understand the difference between float and int. float variables are used when you need decimals in your calculations. int is used when you need integers. The problem in this exercise was the formulation of r. Now r is = 2/12, this means that when we type r as that, the computer assumes that it is an integer and treats it as such. So, it will convert the 0.166667 into 0. To overcome this, all you have to do is type 2.0 instead of 2 alone.

The %0.2 command restricts the float variable to 2 decimal places. By default, it has 6 decimal places.

I have used the function scanf_s instead of scanf simply because my compiler does not work with scanf.

A switch that is configured to use the Spanning Tree Protocol will place a port in ____________ mode if sending traffic to it ma

Rashid [163]

Answer:

Blocking Mode

Explanation:

Spanning Tree Protocol is used to allow path redundancy in the network without creating cycles/circles also called loops.

When two parts of the switched network are connected via two or more Layer 2 switches this result in a loop.

This affects the performance of the network as the result of broadcast packets flooding.

STP puts one port of the switch to forwarding mode and the rest of the ports within the same part of the network to the blocking mode to avoid broadcast packet flooding. STP puts all the ports that are allowing redundant paths to blocking mode and the one port that is left after this is placed in forward mode.

Spanning Tree Algorithm is used by STP to determine the optimal path of switch to the network.

Bridge Protocol Data Units are used to share the information about the optimal path determined by the spanning tree algorithm with other switches.

This information helps STP to eliminate the redundant paths.

So this is how STP allows only one active path to the destination while blocking all other paths to avoid switching loop.
