Answer:
Following are the code to the given question:
#include <iostream>//header file
#include <cstring>//header file
using namespace std;
int main() //main method
{
char personName[100] = "Albert Johnson";//defining a char array
char searchChar;//defining char variable
char *searchResult = nullptr;//use pointer type char variable to holding value as nullptr
searchChar = 'J';//holding char value
char *ptr = personName;//using pointer type char variable that holds a value
while (*ptr) //defining while loop that checks *ptr value
{
if (*ptr == searchChar) //use if that check *ptr value is equal to searchChar
{
searchResult = ptr;//holding ptr value in searchResult
}
ptr++;//incrementing ptr value
}
if (searchResult != nullptr) //use if that checks searchResult value not equal to nullptr
{
cout << "Character found." << endl;//print message
}
else //else block
{
cout << "Character not found." << endl;//print message
}
return 0;
}
Output:
Character found.
Explanation:
In this code inside the main method, a char array is declared that holds values.
In the next step, some char variable and pointer type char variable are declared that holds values.
Inside the while loop, the pointer variable is used, and in the if the block it checks its value and holds its values.
Outside the loop, it checks searchResult value not equal to nullptr and prints the value as per the given condition.

return self.Name() + ", " + self.staffnumber
x = Person("Sammy", "Student")
y = Employee("Penny", "Peters", "805")
print(x.Name())
print(y.GetEmployee())
Answer:
Explanation:
There is nothing wrong with the code it is complete. The Employee class is correctly extending to the Person class. Therefore, the Employee class is a subclass of Person and Person is the parent class of Employee. The only thing wrong with this code is the faulty structure such as the missing whitespace and indexing which is crucial in Python. This would be the correct format. You can see the output in the picture attached below.
class Person :
def __init__(self, first, last) :
self.firstname = first
self.lastname = last
def Name(self) :

In cel E10, create a fomula by entering cell references
that adds cells B9 and B10, and then subtracts cell EB.
Answer:
= B9 + B10 - E8
Explanation:
Required
Create a formula in E10 that subtracts E8 from the sum of B9 and B10
The sum of B9 and B10 is represented with B9 + B10
When E8 is subtracted, the formula becomes B9 + B10 - E8
To write a formula in Excel, you start with " = " sign.
So, type the following in cell E10
= B9 + B10 - E8
The cell references in this case are the name of the cells; i.e. B9, B10 and E8

Consider the following instance variables and incomplete method that are part of a class that represents an item. The variables years and months are used to represent the age of the item, and the value for months is always between 0 and 11, inclusive. Method updateAge is used to update these variables based on the parameter extraMonths that represents the number of months to be added to the age.
private int years;
private int months; // 0 <= months <= 11
public void updateAge(int extraMonths)
{
/* body of updateAge */
}
Which of the following code segments shown below could be used to replace /* body of updateAge */ so that the method will work as intended?
I int yrs = extraMonths % 12;
int mos = extraMonths / 12;
years = years + yrs;
months = months + mos;
II int totalMonths = years * 12 + months + extraMonths;
years = totalMonths / 12;
months = totalMonths % 12;
III int totalMonths = months + extraMonths;
years = years + totalMonths / 12;
months = totalMonths % 12;
a. I only
b. II only
c. III only
d. I and II only
e. II and III
Answer:
e. II and III
Explanation:
Given
The above code segment
Required
Which can complete the updateAge() method
From the program we understand that the updateAge() will update the year and month based on the extraMonths passed to it.
For instance
[tex]years = 6[/tex] and [tex]months = 8[/tex]
updateAge(5) will update years to 7 and month 1
Having established that, next we analyze options I, II and III
Code I
1. This divides extraMonths by 12 and saves the remainder in yrs.
For instance: 15 months = 1 year and 3 months. So:
[tex]yrs = 3[/tex]
2. This divides extraMonths by 12 and saves the whole part in mos
For instance: 15 months = 1 year and 3 months. So:
[tex]mos = 1[/tex]
3. This updates the value of years by the result of 1 (i.e. the remaining months)
4. This updates the value of years by the result of 2 (i.e. the remaining years)
[tex]months = months + mos;[/tex]
Conclusion:, (I) is incorrect because years and months were updated with the wrong values
Code II
1. This converts years to months, then add the result of the conversion to extraMonths + month
For instance: [tex]years = 3; months = 6; extraMonths = 15[/tex]
[tex]totalMonths = 3 * 12 + 6 + 15 = 57\ months[/tex]
2. This calculates the number of years in totalMonths
[tex]years = totalMonths / 12;[/tex]
i.e [tex]years = 57/12 = 4[/tex]
3. This divides totalMonths by 12 and saves the remainder in months
[tex]months = totalMonths \% 12;[/tex]
i.e. [tex]months = 57\%12 = 9[/tex]
Rough Calculation
[tex]years = 3; months = 6; extraMonths = 15[/tex]
[tex]3\ years + 6\ months + 15\ months = 4\ years\ 9\ months[/tex]
Conclusion: Code II is correct
Code III
1. This calculates the total months
For instance: [tex]years = 3; months = 6; extraMonths = 15[/tex]
[tex]totalMonths = 6 + 15 = 21\ months[/tex]
2. This calculates the number of years in totalMonths, then add the result ot years
[tex]years = years + totalMonths / 12;[/tex]
i.e. [tex]years = 3 + 21/12 = 3 + 1 = 4[/tex]
3. This divides totalMonths by 12 and saves the remainder in months
[tex]months = totalMonths \% 12;[/tex]
i.e. [tex]months = 21\%12 = 9[/tex]
Rough Calculation
[tex]years = 3; months = 6; extraMonths = 15[/tex]
[tex]3\ years + 6\ months + 15\ months = 4\ years\ 9\ months[/tex]
Conclusion: Code III is correct

One of the senior wizards Yee Sian was trapped in a maze during a mission. The maze has n * m cells, labelled from (0, 0) to (n-1, m-1). Starting at cell (0, 0), each time Yee Sian can only take one step, either to the right or down. We wish to find out the number of possible paths to the destination (n - 1, m - 1). A sample path is shown in the figure below.
Having learnt the technique of speeding up the pascal function through memoization, you decide to apply it here. If Yee Sian can walk out by himself (number of paths > 0), tell him how many ways there are. Otherwise, report to Grandwizard and send a rescue team.
Write a function num_of_paths that takes in two integers representing the number of rows (n) and columns (m) in a maze and returns an integer value of number of paths from cell (0, 0) to cell (n - 1, m - 1). The table and skeleton code are given to you. Your table is essentially a dictionary that stores (i, j): val pairs which indicate the number of paths from cell (0, 0) to cell (i, j).
Note: You may assume that all inputs n and m are valid. i.e. n > 0, m > 0.
Incomplete Code:
table = {} # table to memoize computed values
def num_of_paths(n, m):
# your code here
pass
Test Cases:
num_of_paths(1, 100) 1
num_of_paths(123, 1) 1
num_of_paths(3, 3) 6

What type of light comes from reflections off other objects?
Encapsulation is a form of information hiding and an important characteristic of object-oriented programming. When a programmer accesses a property that has been encapsulated, he/she has no way of knowing how that property is implemented. All he/she knows is how to access that property via the public setter and getter methods. What are some examples of encapsulation or information hiding in the Bible
There are a whole lot of encapsulation or information hiding examples in the Bible. Here are about 3 of them:
i. The parables of Jesus. Many times Jesus spoke in parables to teach His disciples and until He's explained they would not get the meaning.
ii. The interpretation of dreams by Joseph. A noticeable example is the one of the baker and the butler in Genesis 40. Each of them - the butler and the baker - both had a dream but the actual meaning and interpretation of those dreams were not known by them.
iii. Peter walking on water is yet another example of encapsulation. He was only following the instruction of the master. How he was able to walk on water was a mystery to him. Only Christ the master knew how. Encapsulation.

A deferred annuity is an annuity which delays its payouts. This means that the payouts do not start until after a certain duration. Notice that a deferred annuity is just a deposit at the start, followed by an annuity. Your task is to define a Higher-order Function that returns a function that takes in a given interest rate and outputs the amount of money that is left in a deferred annuity.
Define a function new_balance(principal, gap, payout, duration) that returns a single-parameter function which takes in a monthly interest rate and outputs the balance in a deferred annuity. gap is the duration in months before the first payment, payout is monthly and duration is just the total number of payouts.
Hint: Note that duration specifies the number of payouts after the deferment, and not the total duration of the deferred annuity.
def new_balance(principal, gap, payout, duration):
# Complete the function
return
# e.g.
# test_balance = new_balance(1000, 2, 100, 2)
# result = test_balance(0.1)

Answer:
def new_balance(principal, gap, payout, duration):
def calculate_balance(interest_rate):

for i in range(gap):
balance *= (1 + interest_rate/12)
for i in range(duration):
balance *= (1 + interest_rate/12)
balance -= payout
return balance
return calculate_balance
Explanation:
Answer:
def new_balance(principal, gap, payout, duration):
# convert monetary amounts to cents
principal_cents = principal * 100
payout_cents = payout * 100
def balance(rate):
# calculate the interest earned during the deferment period in cents
