Most computers have three types of ports: serial, parallel, and USB. A serial port is a type of interface that connects a device to the system unit by transmitting data only one bit at a time. Serial ports usually connect devices that do not require fast data transmission rates, such as a mouse, keyboard, or modem.

Shtirlitz [24]

Answer:

Written in Python

cost = float(input("Cost of one room: "))

numrooms = int(input("Number of rooms: "))

days = int(input("Number of days: "))

salestax = float(input("Sales tax (%): "))

print("Cost of one room: "+str(cost))

print("Discount: 0%")

print("Number of rooms: "+str(numrooms))

print("Number of days: "+str(days))

totalcost = numrooms * cost

print("Total cost: "+str(totalcost))

salestax = salestax * totalcost/100

print("Sales tax: "+str(salestax))

print("Total Billing: "+str(salestax + totalcost))

Explanation:

The next four lines prompts user for inputs as stated in the question

<em>cost = float(input("Cost of one room: "))</em>

<em>numrooms = int(input("Number of rooms: "))</em>

<em>days = int(input("Number of days: "))</em>

<em>salestax = float(input("Sales tax (%): "))</em>

<em />

The following line prints cost of a room

print("Cost of one room: "+str(cost))

The following line prints the discount on each room (No information about discount; So, we assume it is 0%)

print("Discount: 0%")

The following line prints number of rooms

print("Number of rooms: "+str(numrooms))

The following line prints number of days

print("Number of days: "+str(days))

The following line calculates total cost of rooms

totalcost = numrooms * cost

The following line prints total cost

print("Total cost: "+str(totalcost))

The following line calculates sales tax

salestax = salestax * totalcost/100

The following line prints sales tax

print("Sales tax: "+str(salestax))

The following line calculates and prints total billings

print("Total Billing: "+str(salestax + totalcost))

which of the following indicates that the loop should stop when the value in the quantity variable is less than the number 50​
yan [13]

Answer:

while (quantity >= 50)

Explanation:

Required

Stop when quantity is less than 50

To do this, we make use of a while statement and the syntax is:

while (condition){ }

If the loop should stop when quantity is less than 50; then it means the loop would continue when quantity is greater or equal to 50

So, we have:

while (quantity >= 50)

emmainna [20.7K]

Answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

// function to compute sum and product

void sum_prod(int input)

{

   int sum=0;

   long long product=1;

   // compute sum of all from 1 to input number

   for(int i=1;i<=input;i++)

   {

       sum=sum+i;

   }

   // print sum

   cout<<"sum of all from 1 to "<<input<<" is:"<<sum<<endl;

   // compute product of all from 1 to input number

   for(int i=1;i<=input;i++)

   {

       product=product*i;

   }

   // print product

   cout<<"product of all from 1 to "<<input<<" is:"<<product<<endl;;

}

// driver function

int main()

{

   int n;

   cout<<"enter the number (0 to stop):";

   // read the input number

   cin>>n;

   // repeat until the user enter 0

   while(n)

   {

   // call the function to compute sum and product

      sum_prod(n);

      cout<<"enter the number (0 to stop):";

      cin>>n;

   }

return 0;

}

Explanation:

Read a number from user. Then call the function to calculate the sum and product of all number from 1 to input. In the function sum_prod(),create two variables "sum" and "product" to calculate the sum and product. Then print the output.This function will be called until user enter 0 an input.

Output:

enter the number (0 to stop):5

sum of all from 1 to 5 is:15

product of all from 1 to 5 is:120

enter the number (0 to stop):10

sum of all from 1 to 10 is:55

product of all from 1 to 10 is:3628800

enter the number (0 to stop):0
