Privacy program, lab2pr2.py Write an automated password-hiding program that
could be used in automatic password manager. The program will first read user
passwords, one at a time, and store them in a list. When the user enters an empty
string (just hits enter), they are finished with the input. The program should
then replace each password with a string of * corresponding to the length of the

original password. As the output, the program should print the original list and
the resulting list.
For instance, here’s the output from a sample run of your program:
Please enter a password (press [enter] to finish): Tulane123
Please enter a password (press [enter] to finish): Bruff
Please enter a password (press [enter] to finish): LBCLBC
Please enter a password (press [enter] to finish):
[’Tulane123’, ’Bruff’, ’LBCLBC’]
[’*********’, ’*****’, ’******’]

In the United States, a Social Security number (SSN) is a nine-digit number that
is a national identification number for taxation purposes. Write a program that
asks the user for their social security number in DDDDDDDDD format (where
D is digit). The program first performs a basic check if the number corresponds
to actual SSN by making sure it has 9 characters in it. If yes, it creates a string
variable new ssn with SSN in user-friendly DDD − DD − DDDD format and
prints it. If not, it prints an error message Incorrect SSN length.

A new author is in the process of negotiating a contract for a new romance novel. The publisher is offering three options.

• In the first option, the author is paid $5,000 upon delivery of the final manuscript and $20,000 when the novel is published.
• In the second option, the author is paid 12.5% of the net price of the novel for each copy of the novel sold.
• In the third option, the author is paid 10% of the net price for the first 4,000 copies sold, and 14% of the net price for the copies sold over 4,000.

The author has some idea about the number of copies that will be sold and would like to have an estimate of the royalties generated under each option.

Instructions

Write a program that prompts the author to enter:

1. The estimated number of copies that will be sold.
2. The net price of each copy of the novel

The program then outputs:

1. The royalties under each option
2. The best option the author could choose.
   • Ex. If option 1 is the best, output Option 1 is the best

(Use appropriate named constants to store the special values such as royalty rates and fixed royalties.)

Since your program handles currency, make sure to use a data type that can store decimals with a decimal precision of 2.

Example input:

120
22.99

Expected Output:

25000.0

344.8

275.8

Option 1 is the best

in java. using the following template as a method,

public static void shellSort(int[] array) {

create a program that counts the number of comparisons and swaps of the sorting method does using

int array1[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; // Best Case Test
int array2[] = {10, 9, 8, 7, 6, 5, 4, 3, 2, 1}; // Worst Case Test
int array3[] = {10, 4, 8, 2, 6, 1, 9, 3, 7, 5}; // Average Case Test

and have the counsel print out the results.

Using C++ : What am I doing wrong!?!?

Problem Instructions: Implement a program that repeatedly outputs an I of a size entered by the user. Prompt the user for a size. If -1 is entered, quit the program. If an even number or a number smaller than 3 is entered, prompt the user again. Then output a shape of # characters that represent an I. Repeat the program until -1 is entered.

What I have so far:

#include <iostream>

#include <iomanip>

using namespace std;

int main()

{

int num;

cout << endl;

cout << " Please enter an ODD number greater than 2: " << endl;

cin >> num;

if (num!= -1)

{

while (num >= 3 && num % 2 == 1)

{

do //Runs if num is invalid

{

if (num %2 == 0)

{

//header

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

{

cout << "#";

}

//middle

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

{

cout << endl;

for (int i = 1; i <= num / 2; i++)

{

cout << " ";

}

cout << "#";

}

cout << endl;

//footer

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

{

cout << "#";

}

}

} while (num >= 3 && num % 2 == 1);

}

}

return 0;

}

Integer value calculator: Write a program using C++ that acts as a calculator. The program should ask the user for two numbers and an operator. Then the program must print the result using the two input values and the operator.

Prompts and input requirements. Ask the user for two integer values and a value that indicates the operation. Likely you will want to choose the normal operators: + - * / %.

Output Requirements: Make your output easy to understand, both in the prompts and when printing the result.

Input Validation. The program should validate all input from the user and print an error message if the input is not valid. The integer values must be between -30,000 and + 30,000 and the operators must be one of these: + - * / %. If the input is not valid, the program should exit without printing a result.

Write a program that asks the user for a number of seconds and tells them how
many hours, minutes and seconds it is. Make sure your program works correctly
for values smaller than the whole hour or whole minute. Here’s what the sample
output from several runs of your program would look like:
Please enter the number of seconds: 2
2 seconds
>>>
Please enter the number of seconds: 500
8 minutes 20 seconds
>>>
Please enter the number of seconds: 20000
5 hours 33 minutes 20 seconds
Hint: you may find mod and div operations helpful here. You will need to use
branching statements (ifs) in this program.

Internet Service provider Part 1 (Java Program)

An Internet service provider has three different subscription packages for its customers:

Package A: For $9.95 per month 10 hours of access are provided. Additional hours are $2.00 per hour.

Package B: For $13.95 per month 20 hours of access are provided. Additional hours are $1.00 per hour.

Package C: For $19.95 per month unlimited access is provided.

Write a program that calculates a customer’s monthly bill. It should ask the user to enter the letter of the package the customer has purchased (A, B, or C) and the number of hours that were used. It should then display the total charges.

Part 2

Modify the program you wrote for Part 1 so it also calculates and displays the amount of money Package A customers would save if they purchased Package B or C, the amount of money Package B customers would save if they purchased Package A or Package C, and the amount of money Package C customers would save if they purchased Package A or Package B . If there would be no savings, no message should be printed.

Write a MIPS Assembly Language program to perform the following operations:

Request and read two integers from the console (Dn and Up),

Call a recursive function to compute the result

{

if( Dn < 1 ) return 0;

else return Dn * Up + RecurseFunc( Dn - 1, Up + 1 );

}
