Visual C# 2017

Write a program named Eggs that declares four variables of type int to hold the number of eggs produced in a month by each of four chickens, and assign a value to each variable.

Sum the eggs, then display the total in dozens and eggs. For example, if the total number of eggs was 95, the output would be 95 eggs is 7 dozen and 11 eggs.

Note: For final submission ensure that the total number eggs equals 127.

My code in python keeps failing when the investment is 12 and the market price is 1. I'd like to keep my code, just fix the issue. Thank you.

This is what the automated tests keep saying:

market_price = 1

available_funds = 12

Expected output: Buy 2 shares

Actual output : Hold Shares

We can profit most by buying 2 shares

--------------------------------------------------------------

I'm stopping the tests for now,

because it looks like you still have some work to do.

You should review the test feedback above,

and then work to resolve these issues in your code.

I Ran 7 of 8 test(s).

Your code passed 4 test(s).

Your code failed 3 test(s).

Continue to build on your success,

and focus on creating the simplest code

that will pass just one more test.

Here is my Code:

def trade_action(current_stock, purchase_price, current_price, investment):
# Write your code here.
if purchase_price>= current_price:
investment-=10
number_shares = investment/current_price
profits= (number_shares*current_price-purchase_price)-10
if profits >= 0:
return number_shares
else:
return "Hold Shares"
elif current_price>= purchase_price:
if current_price-purchase_price*current_stock-10>0:
return "Sell Shares"
else:
return "Hold Shares"

As stated. The problem is when the computer inputs 12 for investment and 1 for market share, the program returns Hold Shares, when it is suppose to return purchase 2 shares.

Project Challenge: Automatic Stock Trader

DIRECTIONS

Many investment management companies are switching from manual stock trading done by humans to automatic stock trading by computers. You've been tasked to write a simple automatic stock trader function that determines whether to buy, sell, or do nothing (hold) for a particular account. It should follow the old saying "Buy low, sell high!"

This function takes 4 input parameters in this order:

1. current_shares - current number of shares of this stock in the account (int).
2. purchase_price - price (per share) paid for current stock in the account (float).
3. market_price - current market price (per share) of stock in the account (float).
4. available_funds - maximum amount the client is willing to spend on a stock purchase (float).

Any transaction (buy or sell) costs $10. This $10 must be paid out of the available_funds for a purchase, or out of the proceeds of a stock sale. Be sure to account for this fee in your profit calculations.

A purchase would be considered profitable when the current market price is lower than the purchase price, and the available funds will allow us to buy enough shares so that the difference in value will cover the $10 transaction fee. In this case the function should return the string "Buy # shares" where # is an integer representing the number of shares to purchase.

A sale would be considered profitable when the current market price is higher than the purchase price, and the value gained by selling the shares will cover the $10 transaction fee. In this case the function should return the string "Sell # shares" where # is an integer representing the number of shares to sell.

If neither a buy nor a sell would be profitable, then the function should return the string "Hold shares."

Here are some test cases that your function should satisfy:  

Rationale for test cases:

Test 1
Even though the current market price is very low (compared to the purchase price), after paying the $10 transaction fee, we would not have any funds left to buy shares; so we can only hold.

Test 2
After paying the $10 transaction fee, there are enough funds remaining to buy 11 shares. At a purchase_price vs. market_price difference of $1 per share, our 11 shares represent a value gain of $11 dollars, which is $1 more than the $10 transaction fee - so we come out $1 ahead.

Test 3
After paying the $10 transaction fee, there are enough funds remaining to buy 2 shares. At a purchase_price vs. market_price difference of $11 per share, our 2 shares represent a value gain of $22 dollars, which is $12 more than the $10 transaction fee - so we come out $12 ahead.

Test 4
Selling our 1 share for $11 will leave us with just $1 after we pay the $10 transaction fee. That is the same as what we paid for it, and we won't make any profit - so we should hold.

Test 5
With a market_price vs. purchase_price vs. difference of $2 per share, we stand to make $20 from the sale of our 10 shares. This is $10 more than the price of the transaction fee, so we will come out $10 ahead - therefore we should sell all 10 shares.

Test 6
Our 1 share is worth $11 more than we paid for it at the current market price. The $11 dollars obtained by selling that share now will still leave us with a profit of $1 after paying the $10 transaction fee. Profit is profit, so we should sell.

Things to think about when you’re designing and writing this program:

1. Look for opportunities to use variables as a way to name things, and to break larger more complex expressions down into simpler expressions.
2. Spend some time choosing your names carefully. Names should be descriptive.
3. Try to design and write your code a few lines at a time. Design and write a few lines, then run some tests to see if these lines are doing what you want them to do. If they are not, then analyze and correct them before you move on to the next few lines of code.

1. Write a program that computes the smallest and largest of a set of values that are stored in an array. Ask the user for the set size (and hence the array size). Populate the array with user input.

1. If an attacker sends a large number of probe packets via IPv4, you can block them by blocking the attacker’s IP address. Now suppose the attacker uses IPv6 to launch the probes; for each probe, the attacker changes the low-order 64 bits of the address. Can these probes be blocked efficiently? If so, what do you have to block? Might you also be blocking other users? 2. Suppose someone tried to implement ping6 so that, if the address was a link-local address and no interface was specified, the ICMPv6 Echo Request was sent out all non-loopback interfaces. Could the end result be different than conventional ping6 with the correct interface supplied? If so, how likely is this?

1. Write a binary search algorithm in C language by performing following steps:
2. Prompt the user to enter the number of array elements (say, N).  
3. Read the N different values (define these values to be of type integer).  
4. Read the element (integer value) which you want to search.
5. Invoke a function to display the values in the array. The function should take the array reference and number of elements as arguments and should have the return type as void. The function should loop through the array and print the array values one per line.
6. Invoke a function to search in the array using binary search (this function should take the array reference and number of elements as the arguments and the search element). The binary search function should have the return type as integer and it should return the array index when the search value is found, otherwise it should return -1.
7. The main program should print a message if the search value is found and the corresponding position in the array where it was found. If the search value was not found, then the main program should also print a message saying that the search value does not exist in the given array.

i dont know.
this is the full task

on python 3.6:

Write a program that will quickly estimate pi to a precision of 1e-4 using Archimedes approach of averaging polygon perimeters. Your program should employ a loop where the number of sides of the polygon are increased each iteration until the absolute value of the difference between the current estimate and the previous estimate is less than 1e-4. l. The program should output the estimate of pi and the number of iterations needed to reach the desired level of precision.

the code for the finding pi using the Archimedes approach is:

numside_ins=float(input(enter the number of sides of the inscribed polygon))

numside_cis=float(input(enter the number of sides of the circumscribed polygon))

diameter= 1
length_ins= 2*(diameter/2)*sin(pi/numside_ins)
peri_ins= numside_ins*length_ins
length_cir= 2*(diameter/2)*tan(pi/numside_cir)
peri_cir = numside_cir * length_cir
ave_peri=((peri_cir + peri_ins) / 2)
found_pi= ave_peri/diameter
print(found_pi)
