Searching an Array for an Exact Match
Summary
In this lab, you use what you have learned about searching an array to find an exact match to complete a partially prewritten C++ program. The program uses an array that contains valid names for 10 cities in Michigan. You ask the user to enter a city name; your program then searches the array for that city name. If it is not found, the program should print a message that informs the user the city name is not found in the list of valid cities in Michigan.
The file provided for this lab includes the input statements and the necessary variable declarations. You need to use a loop to examine all the items in the array and test for a match. You also need to set a flag if there is a match and then test the flag variable to determine if you should print the the Not a city in Michigan. message. Comments in the code tell you where to write your statements. You can use the previous Mail Order program as a guide.
Instructions
Ensure the provided code file named MichiganCities.cpp is open.
Study the prewritten code to make sure you understand it.
Write a loop statement that examines the names of cities stored in the array.
Write code that tests for a match.
Write code that, when appropriate, prints the message Not a city in Michigan..
Execute the program by clicking the Run button at the bottom of the screen. Use the following as input:
Chicago
Brooklyn
Watervliet
Acme
CODE:
// MichiganCities.cpp - This program prints a message for invalid cities in Michigan.
// Input: Interactive

// Write your loop here
// Write your test statement here to see if there is
// a match. Set the flag to true if city is found.
// Test to see if city was not found to determine if
// "Not a city in Michigan" message should be printed.
return 0;

In what setting should a bidirectional microphone be used and why?
Bidirectional microphones have a very constricted pickup angle, making them useful for separating a single voice or mechanism in the presence of other sound sources, as lengthy as nothing is directly behind the mic. They are useful for picking up two sources that are next to each other.
What is bidirectional microphone?The pressure gradient principle underpins this type of microphone. The sound can travel through the membrane on both sides.
When the sound on the front and backside of the diaphragm differs, the microphone sends a signal.
Bidirectional microphones have a particularly narrow pickup angle, which makes them advantageous for distinguishing a single voice or framework in the involvement of other sound sources, as long as nothing is directly behind the mic.
They are useful for detecting two sources that are close together.
Thus, in this setting a bidirectional microphone can be used.

A. It tests whether the condition returned by the callback function holds for all items in array.
B. It returns the value of the first element in the array that passes a test in the callback function.
C. It tests whether the condition returned by the callback function holds for at least one item in array.
D. It returns the index of the first element in the array that passes a test in the callback function.
Option c is correct. It tests whether the condition returned by the callback function holds for at least one item in array.
Every element in the array is put through the supplied test by the provided function using the every() method. It gives back a Boolean result. Until it locates the element for which callback function returns a false result, the every method calls the given callback function once for each element present in the array.
The every method immediately returns false if such an element is discovered. Every returns true if callback function does not return a truthy value for any of the items.
Only for array indexes with assigned values is callbackFn triggered. For empty slots in sparse arrays, it is not called.
The value of the element, the index of the element, and the Array object being traversed are passed as the three arguments to callbackFn.

Consider two packet switches directly connected by a link of 5000 km,
propagation speed 2.5 X10^8 m/s and transmission rate 1 Mbps. How long does it take to move
a packet of length 1,000 bytes from one packet switch to the other packet switch? Generally,
how long does it take to move a packet of length L over a link of distance d, propagation speed
s, and transmission rate R bps?
The time that is required for the packet to move over the the distance d at the speed s is 0.028 seconds.
The speed that It would take to move it in transmission is given as 0.008 seconds.
How to solve for the required timeThe details that we would have to solve the problem that we have here are given below
The distance = 5000 km, we convert to meters = 5000 * 1000
The speed of the propagation is given as (s) 2.5 x 108 m/s
The propagation delay is given as d / s
= 5000000 / 2.5 x 10^8
= 0.02 this is the value of the propagation
Next we have to find the length of the packet. L = 1000 bytes
this is equal to 8000 bits
The transmission rate is 1 Mbps = 1000000 bits
The transmission delay would be = L/R
= 8000 / 1000000
= 8 / 1000
= 0.008 seconds in transmission
The total required time that is to be gotten would be
Propagation + transmission
= 0.02 + 0.008

(while-loop). Generate a random integer from 1 to 100. Prompt the user to guess the number. Display "Too high" or "Too low", depending on the guess. When the user guesses the right number, display "You got it!". You must keep track of the number of times the user takes to guess the number and report it when the number is correct.
Hints: To generate the random number, use the one below:
import random as rd
answer = rd.randrange(1,101)
TEST CASES: Suppose the number to guess is 40.
Enter guess: 1-100: 50
Too high!
Enter guess: 1-100: 25
Too low!
Enter guess: 1-100: 35
Too low!
Enter guess: 1-100: 40
You got it!
You took 4 tries to guess the number.
Investment Problem: Multiplier Accumulator
Prompt the user to enter the initial investment amount, the annual interest, and the number of years for the investment.
Compute the balance that will be achieved at the end of each of the requested years. Round the balance to 2 decimal places.
Algorithm Hints:
Use a for-loop and range function to generate the year (1, 2, 3,…). The number of iterations is the number of years.
Using the formula (see below), compute the investment balance at the end of each year. Note that I know you could always use Python's exponentiation operator (**) to calculate the final result. But I want you to use iteration (looping) to find the answer! Hint: this is an example of an accumulator that uses multiplication.
For example, if you have $1 and get 4% interest, the amount at the end of the first five years would be:
FV = FV*(1 + APR)**year = 1 * (1 + 0.04) ** 1
FV = FV*(1 + APR)**year = 1 * (1 + 0.04) ** 2
FV = FV*(1 + APR)**year = 1 * (1 + 0.04) ** 3
FV = FV*(1 + APR)**year = 1 * (1 + 0.04) ** 4
FV = FV*(1 + APR)**year = 1 * (1 + 0.04) ** 5
etc.....
If you have an amount that is different than $1 (e.g., $10,000), multiplying $10,000 by the final FV quantity for each year will give you the future value for $10000.
Suggestion: to check your answer, use the exponentiation operator, calculate the result using the above formula, and compare that result with the one using your accumulator approach. The answers should be very close.
Also, you know that \n inside quotes generates a new line. Similarly, \t generates a tab stop, which you can use to generate the two columns in the output.

Enter initial investment: $5000
Enter interest rate: 2.5

Which of the following methods includes or embeds a new node directly ahead of a child node?
a. node.appendChild(new)
b. node.replaceChild(new, old)
c. node.insertBefore(new, child)
d. node.insert(new, old)
Option c is correct. Node.insertBefore(new, child) is the method that includes or embeds a new node directly ahead of a child node.
The Node interface's insertBefore() method places a node as a child of a given parent node ahead of a reference node.
InsertBefore() transfers the specified node to the new place if it already exists in the document. (That is, before adding it to the given new parent, it will automatically remove it from its current parent.)
As a result, a node cannot be present in two places in the document at once. The full contents of the DocumentFragment are moved into the child list of the chosen parent node if the given child is a DocumentFragment. the node that newNode is added before. In the event that this is null, newNode is appended to the end of the node's child nodes.

What would the code be for this?
Answer:
c = 'z'
while c >= 'a':
print(c)
c = c h r(ord(c)-5)
Explanation:
Keep in mind, you could have also chosen to do:
print("z\nu\np\nk\nf\na\n")
but it seems the character arithmetic is what is asked for...
