Is there anyway to solve below problem in Java?

Wherever there is int it gives an error! It's not only line 20! it give an runtime error everywhere get int after string! or even before read string!

cities[i] = sc.next(); //This way does not work!!!!

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.

Be sure to provide the title of the article, the author(s), and the reference for the article.

I recently did an experiment where we had to discover the rate order of the sufrace area of magnesium and hydrochloric acid as well as the activation energy. The point of the experiment was to discover the kinetic parameters of a heterogenous reaction. As I was writing my lab report, I uncovered a similiar experiment however the rate order for their experiment for hydrochloic acid was 2 when mine came out as 1. So I was curious as to how is it possible for the same experiment to produce different rate orders? What factors could change the rate order of a reactant? Thank you for any help you can give me.

Choose a binomial probability experiment. You could flip a coin, or toss a basketball from the free throw line and see if you make the shot or miss, or choose another experiment where the outcome is a success or failure (only two possible outcomes.)  

1) Make a guess about the probability of success before doing the experiment.

2) Repeat the experiment 50 times, and record the results.

3) Calculate the empirical probability of success, and compare it to your original guess. Were you close or were you far off?

4) Write a paragraph explaining how you did the experiment and comparing your results to your guess

1 (a) A pair of dice is rolled, and the number that appears uppermost on each die is observed. Refer to this experiment and find the probability of the given event. (Enter your answer as a fraction.)

The sum of the numbers is either 7 or 11.

(b) An experiment consists of selecting a card at random from a 52-card deck. Refer to this experiment and find the probability of the event. (Enter your answer as a fraction.)

A face card (i.e., a jack, queen, or king) is drawn.

(c) An experiment consists of selecting a card at random from a 52-card deck. Refer to this experiment and find the probability of the event. (Enter your answer as a fraction.)

A black face card is not drawn.
