1. Where (Which directory) you store the database connecting information? parallel to htdocs folder why? no one can access except the admin

2. difference between GET and POST methods

3. Include multiple files: include, include_once, require, require_once

Three employees in a company are selected for a pay increase. You are given a file (salaries.txt) that contains three lines. Each line in the file consists of an employee’s last name, first name, current salary, and percent pay increase. For example, in the first line, the last name of the employee is Miller, the first name is Andrew, the current salary is 65789.87 and the pay increase is 5%. Write a program that reads data from the file and stores the output in another file. The output data must be in the following format: FirstNameInitial lastName updatedSalary Format the output of decimal number to two decimal places. For example, the first line in the output may look like the following: A. Miller 69079.36 I want help to solve it on netbeans

Create an “About Me” HTML webpage.

Use the <h2> Tag to give the page a header with your Full name. The header needs to be in Plum color(Any color other than black, blue – Make the page look good).

The webpage should have a background color that compliments the header color.

Set the content(Anything about yourself!) of the page inside <p> tags and use a different color for it.

Save your file as “AboutMe.html” and upload the file to BB under Exercises/Assignments.

Be as creative as possible !

can you please send me all the codes accordingly so i can use it and for the name and content just use john doe and i'll change accordingly thank you

IN C++ PLEASE:

(1) Extend the ItemToPurchase class per the following specifications:

• Parameterized constructor to assign item name, item description, item price, and item quantity (default values of 0).
• Public member functions
  • SetDescription() mutator & GetDescription() accessor
  • PrintItemDescription() - Outputs the item name and description in the format name: description
• Private data members
  • string itemDescription - Initialized in default constructor to "none"

(2) Create three new files:

• ShoppingCart.h - Class declaration
• ShoppingCart.cpp - Class definition
• main.cpp - main() function (Note: main()'s functionality differs from checkpoint A)

Build the ShoppingCart class with the following specifications. Note: Some can be function stubs (empty functions) initially, to be completed in later steps.

• Default constructor
• Parameterized constructor which takes the customer name and date as parameters
• Private data members
  • string customerName - Initialized in default constructor to "none"
  • string currentDate - Initialized in default constructor to "January 1, 2016"
  • vector < ItemToPurchase > cartItems
• Public member functions
  • GetCustomerName() accessor
  • GetDate() accessor
  • AddItem()
    • Has parameter ItemToPurchase. Does not return anything.
    • Adds the item to cartItems vector as long as the quantity is not zero.
  • IsItemInCart()
    • Has a string (an item's name) parameter. Checks if that item is in cart. If so, returns True else False.
    • Has an integer parameter passed by reference. If the item exists, populates it with index in cartItems vector. ((I ESPECIALLY NEED HELP WITH THIS PART PLEASE)))
  • RemoveItem()
    • Removes item from cartItems vector. Has a string (an item's name) parameter. Does not return anything.
    • If item name cannot be found, output this message: Item not found in cart. Nothing removed.
  • ModifyItem()
    • Modifies an item's description, price, and/or quantity. Has parameter ItemToPurchase with updated data members. Does not return anything.
    • If item can be found (by name) in the cart, check if the input parameter has default values for data members: description, price, and quantity. If not, modify that data member of the item in cart.
    • If item cannot be found (by name) in cart, output this message: Item not found in cart. Nothing modified.
  • GetNumItemsInCart()
    • Returns quantity of all items in cart. Has no parameters.
  • GetCostOfCart()
    • Determines and returns the total cost of items in cart. Has no parameters.
  • PrintTotal()
    • Outputs total of objects in cart.
    • If cart is empty, output this message: SHOPPING CART IS EMPTY
  • PrintDescriptions()
    • Outputs each item's description.

How might you test for possible interface misunderstanding in software? Here “interface misunderstanding" refers to calling functions on an interface with the correct function signatures but with incorrect intent.

what are the most important things of Audit Policies and Event Viewer in windows?

mySQL database question.. I have a database that has the following tables:

User (Id, Name, Gender) Primary key = Id

Friends (Id1, Id2, Startdate) Primary key = (Id1, Id2) Foreign keys are also Id1, Id2 pointing to User(Id)

Comments (CommentId, Poster, Recipient, Text, PostDate) Primary key = (CommentId) Foreign Keys are Poster, Recipient pointing to User(Id)

I need to answer the following queries:

5. List Users who have posted comments to all female users

6. List User(s) who have received comments from the most number of users

When finding users, all I need to list is the Id of the user.
