(SQL Coding)

Create a read only view called view_emp_salary_rank_ro that selects the last name and salary from the o_employees table and ranks the salaries from highest to lowest for the top three employees.

Write a program with two input values, Hours and Rate. The program should first calculate Gross pay, which is your pay before deductions. The program should then calculate the following three deduction amounts: Federal Tax (20% of Gross), State Tax (5% of Gross), Social Security Tax (6.2% of Gross). Then your program should calculate Net pay, which is your Gross pay minus the three deductions. The output should be all five of the calculated values.

JAVA PROGRAM, Create the game "Rock, Scissor, Paper":

1. Make the AI pick randomly. You need to look up Random numbers in Java.
2. First ask the user what language they want to play in. Choice 1 is English, but choice 2 can be whatever real language you want.
3. Your first loop is making sure they enter good input.
4. If there is a tie you don't give them the option to play again. They have to.
5. Outer loop runs until they say they don't want to play again.
6. Display how many wins and losses the player had only after they quit. Remember, variables are free. If you need the computer to keep track of something, make a variable.

Program 3: Command Line Calculator

Topics: Functions or methods, global variables

Overview

You will build a simple command line calculator. It supports addition (add), subtraction (sub), multiplication (mul), division (div), and calculation of the absolute value (abs). You will use functions to support each type of calculation. You can assume that the numbers are float data types.

Software Specifications

The user interacts with program by entering a command, followed by some parameters at the command prompt “>”. For example, if the user wants to add 4 and 5, he/she enters “add 4 5” and hits the return key. The system then outputs the result of the addition command (in this case, 9).   See sample run output below for more examples.

Once the command’s operation is completed, the system goes back to the command prompt waiting for another command from the user.   The commands are “add”, “sub”, “mul”, “div”, and “abs”. All the commands take two arguments except for “abs” which takes one argument. Each command will call the corresponding function to perform the calculation. Name each function the same name as the command. The “quit” command calls the printStats function and ends the program. The printStats function prints the number of times each function were called (executed). To keep track of function call usage, you will need global variables which can be shared across functions.

Parsing the command line

Your program will read the command as a single line. It then splits it into several tokens. The first is the command. Any other tokens after the first are the parameters. To parse a command, simply use the split function on the string. Don’t forget to convert the parameters to floats so that you can perform arithmetic operations.

The code below shows you how to use the split function to extract the command and the parameters.

>>> userinput="add 1 2"
>>> tokens = userinput.split(" ")
>>> print(tokens[0])
add
>>> print(tokens[1])
1
>>> print(tokens[2])
2

Implement a stack in C++ using an array, not an array list.

Make your stack size 5 when you test it, but do not hardcode this! You should be able to change the size for testing purposes with the change of one variable.

DO NOT use Stack class defined in C++

Implement the following methods in your stack class.

• stack() creates an empty stacks, stack s is new and empty.
• push(item) adds a new item to the stack s, stacks is modified.
• pop() removes and returns an item, stack s is modified.
• isEmpty() returns a boolean and tests for an empty stacks, stack s is not modified.
• isFull() returns a boolean and tests for an full stacks, stack s is not modified.
• size() returns the int size of the stacks, stack s is not modified
• print() prints the stacks from front to rear, stack s is not modified.
• top() prints the front element, stack s is not modified.

Write your own Driver file to show that you have implemented all the methods of the stack. A psuedocode example is listed below to guide you. Use print statements as well to show the popped elements, to show the stack after some pushes, to print the size of the stack.

• push(redShirt)
• push(greenShirt)
• push(yellowPants)
• push(purpleSock)
• push(pinkSocks)
• printStack()
• size()
• push(blueShirt)
• size()
• pop()
• pop()
• size()
• pop()
• printStack()
• top()
• pop()
• pop()
• printStack()
• size()
• isEmpty()
• printStack()

Python - Rewriting a Program

Rewrite Program 1 using functions. The required functions are in the table below.

Create a Python program that will calculate the user’s net pay based on the tax bracket he/she is in. Your program will prompt the user for their first name, last name, their monthly gross pay, and the number of dependents.

The number of dependents will determine which tax bracket the user ends up in. The tax bracket is as follows:

• 0 – 1    Dependents:    Tax = 20%
• 2 – 3    Dependents:    Tax = 15%
• 4+        Dependents:    Tax = 10%

After calculating the net pay, print the name of the user, the monthly gross pay, the number of dependents, the gross pay, the tax rate, and the net pay.

The formula to compute the net pay is: monthly gross pay – (monthly pay * tax rate)

Sample run:

Enter your name: Ron Swanson
Enter your gross pay: $3500
Enter number of dependents: 0

Name:      Ron Swanson
Gross pay: $3500.00
Dependents: 0
Tax rate: 20%
Net Pay: $2800.00

Simplify (A xor B) + (A xor C) using K-maps, does  (A xor B) + (B xor C) have the same K-map?

•A theater owner agrees to donate a portion of gross ticket sales to a charity

•The program will prompt the user to input:

−Movie name

−Adult ticket price

−Child ticket price

−Number of adult tickets sold

−Number of child tickets sold

−Percentage of gross amount to be donated

•Inputs: movie name, adult and child ticket price, # adult and child tickets sold, and percentage of the gross to be donated

•The program needs to:

1.Get the movie name

2.Get the price of an adult ticket price

3.Get the price of a child ticket price

4.Get the number of adult tickets sold

5.Get the number of child tickets sold

1)     The provided reorder.cpp file has some code for a function that reorders the values in 3 parameters so that they are in ascending order.

·Start with a function void swap(int &val1, int &val2) that swaps the values of val1 and val2. You will need a local variable to hold the value of one of the parameters to let you do this.

·Write the reorder function called in main(). It should call swap() to exchange values when appropriate.

·Add statements to main() to be able to try out the 3 cases below

Driver to test reorder()

Case 1: values are already in correct order -- leave them alone

1 2 3

Case 2: first > second and first < third

-5 -2 0

Case 3: first > second > third

6 8 10

reorder.cpp

// Reordering values in variables
#include <iostream>

using namespace std;

// swap the values in the two reference integer parameters
void swap(int &val1, int &val2) {

}

// reorder 3 integer values so that
// first parameter has smallest value, second parameter has middle value,
// third parameter has largest value


int main()
{
    int val1 = 1, val2 = 2, val3 = 3;

    cout << "Driver to test reorder()" << endl;
    cout << "Case 1: values are already in correct order -- leave them alone" << endl;
    reorder(val1, val2, val3);
    cout << val1 << " " << val2 << " " << val3 << endl;

Make a python function that inputs f : a function whose root you wish to find, x0 : an initial guess for the root, x1 : an second guess for the root, and k : a number of iterations, and output and outputs a list of the results of performing the secant method k times starting from x0 and x1. Use your function to check if the secant method has the claimed rate of convergence when applied to f ( x ) = e x + x starting with x 0 = 3 and x 1 = 2

1. The value of the expression that evaluates whether the length of the above hypotenuse is 5
2. The area of a disk of radius a
3. The value of the Boolean expression that checks whether a point with coordinates x and y is inside a circle with center (a, b) and radius r

Express each of these statements using quantifiers. Then form the negation of the statement sothat no negation is to the left of a quantifier. Next, express the negation in simple English. In eachcase, identify the domain and specify the predicates.
