C++ Pie bakery

our bakery makes 8 kinds of pie, and receives orders for these pies from on-line buyers. The program you’ll write for this lab knows the price of each pie, so as each new order is received, it’s possible to know how much money the bakery should be receiving.

The program must read in lines of input which have two fields: a pie type and a quantity. With this, the program needs to update the quantity of that type of pie, adding the new order to those already received. You already have code that you’ve written for previous labs that uses getline() and splits the line read in into two separate parts: you get to re-use that here, since you have the same work to do – breaking an input string into two substrings, the first is the name of a kind of pie string and the second is the quantity int.

The program you are writing would be part of a larger system used by the bakery to track and schedule its baking. That’s good for you because it means that the input your program reads is guaranteed not to have bogus order numbers or pie types. A sample input line looks like:

raspberry 10

When the program reaches the end of input it prints out, for each type of pie, the quantity ordered and the total price of that number of those pies. After that it prints out the grand total of all orders (total number of pies, total price).

One problem you face is mapping pie types as strings (how you read them in) to the int index of the array element holding the struct for that pie type. For example, you might read in ”apple” and need to figure out that it’s in array element 3. You must use a function to handle this.

To make life a bit easier, you should initialize an array of struct with these pie types and prices:

peach lemon pumpkin blueberry apple raspberry strawberry cherry

$3.75 $4.50 $5.75 $4.25 $3.70 $6.35 $5.65 $5.20

Of course, you’ll need more than just these two fields in your struct.
A sample run with 100 individual pie orders might produce output like this.

Orders for peach:
Orders for lemon:
Orders for pumpkin:
Orders for blueberry:
Orders for apple:
Orders for raspberry:
Orders for strawberry:
Orders for cherry:

115 value is $ 431.25 128 value is $ 576.00 75 value is $ 431.25 75 value is $ 318.75 71 value is $ 262.70 89 value is $ 565.15 122 value is $ 689.30 53 value is $ 275.60

Grand total: 728 pies for $3550.00

You can test your program with data you type in, or on a test data file you create.

1. Here is a selection from an abstract of a recent study entitled “The effect of health insurance coverage on the use of medical services” by Michael Anderson, Carlos Dobkin, and Tal Gross (2010). NBER Working paper No. 15823.

Substantial uncertainty exists regarding the causal effect of health insurance on the utilization of care. Most studies cannot determine whether the large differences in healthcare utilization between the insured and the uninsured are due to insurance status or to other unobserved differences between the two groups. In this paper, we exploit a sharp change in insurance coverage rates that results from young adults “aging out” of their parents’ insurance plans to estimate the effect of insurance coverage on the utilization of emergency department (ED) and inpatient services. [In the US, children are eligible for insurance coverage through their parents’ insurance only up to their 23rd birthday, at which point they lose eligibility.] Using the National Health Interview Survey (NHIS) and a census of emergency department records and hospital discharge records from seven states, we find that aging out results in an abrupt 5 to 8 percentage point reduction in the probability of having health insurance. We find that not having insurance leads to a 40 percent reduction in ED visits and a 61 percent reduction in inpatient hospital admissions.

1. What two groups are being compared in this study?
2. Identify at least one important methodological difference between the design of this study and the RAND HIE. Give a hypothetical reason why this difference would bias the results.
3. Are the findings of this study generally consistent with the findings from the Oregon Medicaid Experiment?

The table lists foreign exchange rates for August 30, 2018. On that day, how many dollars would be required to purchase 1,200 units of each of the following: British pounds, Canadian dollars, EMU euros, Japanese yen, Mexican pesos, and Swedish kronas? Use the direct quotation for your calculations. Round your answers to the nearest cent.

Drosophila (Pty) Ltd is currently forecasting its short-term financing needs and it requires your assistance in determining these needs and the possible costs of financing. The following information has been gathered and passed on to you.
The bookkeeper extracted an aging report from the system and determined that 40% of sales were paid for in the same month that the sales were made and the remainder was paid 1 month later (all sales were on credit).
The company has access to a R1 000 000 revolving credit facility (line of credit) at a cost of 12% interest per year, assuming 365 days per year. No administrative fees are applicable.
All purchases and other expenses are paid in cash.
Sales from March, April and May were as follows:

Expected sales for June, July and August are as follows:

Additionally, purchases amount to 50% of sales and other costs amount to R200 000 per month but exclude a depreciation expense of R5 000 per month.

REQUIRED:
Draw up a cash budget for this company for June, July and August and determine how much the requisite short-term financing by way of the revolving credit facility will cost (in rand terms) if utilised. Use the space below to make your preliminary calculations and present your cash budget in the space provided below where indicated

Onta Enterprises is seeking to expand operations and is considering increasing production capacity by purchasing the latest plant and equipment.  The following two plants are being considered for acquisition as they are technically superior to the current plant and will enable higher production volumes with lower cost inputs.  The finance department has projected the cash flows for the life of the plant and has asked you as the investment manager to advise the Board on which of these plants to acquire. Onta’s current cost of capital is 12%.

The following information relates to the two plants that are being considered:
