The program is an illustration of loops

<h3>What are loops?</h3>

Loops are program statements that are used to perform repeated operations

#This gets the product name

product = input("Product: ")

#This gets the quantity

quantity= float(input("Quantity: "))

#This initializes the total quantity to 0

total = 0

while(product.upper() != "XXX"):

#This calculates the total price

total+=price

#This gets the product name

product = input("Product: ")

#This gets the quantity

quantity= float(input("Quantity: "))

#This prints the total quantity

print(total)

Write a program that takes an integer n as a parameter and sums all of the multiples of 2 or 5 from 1 to n. For example, if n =

Alex

Answer:

// here is code in c++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main() {

// variable

int num;

int tot_sum=0;

cout<<"enter a number: ";

// read the value of n

cin>>num;

// check the multiple of 2 or 5 from 1 to n

for(int x=1;x<=num;x++)

{

// if multiple of 2 or 5 then add them

if(x%2==0 ||x%5==0)

{

tot_sum=tot_sum+x;

}

// print the sum

cout<<"sum of multiple of 2 or 5 is:"<<tot_sum<<endl;

return 0;

}

Explanation:

Read the number "n" from user.Check every number from 1 to n, if it is a multiple of 2 or 5 then add them to "tot_sum".When the for loop end, "tot_sum" will have sum of all the number which are either multiple of 2 or 5.Print the sum.

Output:

enter a number:11

sum of multiple of 2 or 5 is:35

Given an object context for an Entity Data Model named mmaBooks, which of the following statements would you use to add a Custom

ehidna [41]

Answer:

"mmaBooks.Customers.Add(customer);" is a correct answer for the above question.

Explanation:

Missing information : The correct answer is missing in the question which is defined in the answer part.

If a user wants to add any objects to any collection in the C# programming, then he needs to follow the "Entity_data_model_named. collection_name. ADD(object_name)" syntax. The above question also wants this type of statement.
The option c states the same statements, but there is needs one statement to define the name of db or database models. But the option c does not hold the name of the database models. Hence it is not the correct answer.
And the other options do not follow the syntax to add, hence others is also not a valid option.

Write a program to solve the selection problem. Let k = N/2. Draw a table showing the running time of your program for various v

Brums [2.3K]

So here is the code in Python:

n = 0.00 #this is a float because there are some numbers that are decimals.

while n < 20: #n which is 0.00 and while it is lower than 20 if runs the code below
n = n + 1 #it will add 1 to n everything it runs the code.
k = n / 2 #it will divide whatever n is everytime by 2
print(str(n) + '/2: ') # it's printing the number it's on
print(k) # prints the answer for the n.

You can change n to add by any, make n any num instead of 0.00 and you can change the while condition from n < 20 to any other logical statement. If you want to get creative you can take 2 inputs for numbers and make one of them the starting number and other one is the ending number. Also make sure to make n a number lower than you starting point because if you set n as your starting point then it will skip it.
