Write a program that reads in a number n and then outputs the sum of the squares of the numbers from 1 to n. If the input is 3, for example, the output should be 14, because:
1²+2²+3² = 1 + 4 + 9 = 14.

please give me the code for this question, the question is: while entering the information about different automobile parts in the application, the database administrator enters the prices of some parts incorrectly. the prices are swapped between various parts. create an application that can swap the price of all automobile parts and can assign the correct price against a particular automobile part.

please give me the code for this question, the question is: the application should be able to count the number of automobile parts sold every week depending upon the new entries of parts in the application. if a part is not sold for more than six months after its date of manufacture, the application should prompt a message "Urgent Sale Required".

Write a program that reads one line of input text and breaks it up into words. The words should be output one per line. A word is defined to be a sequence of letters. Any characters in the input that are not letters should be discarded. For example, if the user inputs the line

He said, "That's not a good idea."
then the output of the program should be

He
said
That
s
not
a
good
idea

An improved version of the program would list "that's" as a single word. An apostrophe can be considered to be part of a word if there is a letter on each side of the apostrophe.

How to add from one form string to another form list?

using a console application , develop an interactive application that can assist a user to learn a multiple table program .

a program that first asks for two integer values A and B,program should then pick a random number between A and B and keep it secret. Then ask the user to guess what the number is. The program should continue to ask the user to guess, until the user gets the correct answer. Each time the user makes an incorrect guess, the program should tell the user if the guess was too high, or too low. The program should also tell the user if the guess was outside the range between A and B.

create a console program to create a file of numbers then store even & odd numbers of that file in two seperate files

When the application starts, it should display a message asking the user to enter either option d or
v. The application should execute the following actions for the two options:
d: The application should display the file extension of the stock details.
v: The application should open the stock details file in the read-only mode and display its
contents.
Write the code snippet that Hayley should use to implement the desired functionality in the
application.
In case the user presses any other key, the application should open the stock details file in the
read/write mode, display a message to enter new stock details, and save the details that the user
has entered. Write the code snippet that Hayley should use to accomplish the preceding task. [10
