Explanation:
Write a program that takes as input: - the current hour - the number of hours to add and outputs the new hour. For example, if the inputs are 2 (as the current hour) and 51 (as the number of hours to add), your program should output the answer from part (a) of this problem. Note that your program should always output an integer between 1 and 12. We will get you started with this program with the two lines that gather the input from the user. You'll need to write the rest.
Answer:
The program in Python is as follows:
cTime = int(input("Current Hour: "))
while(cTime <1 ):
cTime = int(input("Current Hour: "))
aTime = int(input("Additional Hours: "))
while(aTime <0):
aTime = int(input("Current Hour: "))
tTime = cTime + aTime
tTime%=12
print("New:",tTime,"hours")
Explanation:
This gets input for current time
cTime = int(input("Current Hour: "))
The following ensures that the user enters a time greater than 0
while(cTime <1 ):
cTime = int(input("Current Hour: "))
This gets input for additional time
aTime = int(input("Additional Hours: "))
The following ensures that the user enters a positive time
while(aTime <0):
aTime = int(input("Current Hour: "))
This calculate the new hours
tTime = cTime + aTime
This gets the hour equivalent between 1 and 12
tTime%=12
This prints the new hour
print("New:",tTime,"hours")

Define the followimg terms as it relates to coding.
Expression
Variable
Assignment operator
Answer and Explanation:
In coding, an expression is used to represent values. It may contain variables and/or constant.
Examples of expressions are:
[tex]a - b[/tex] [tex]a * 2[/tex] [tex]4 - 3[/tex]
Variables are literally memory locations. They are used to storing values, and they assume the values they store during program execution.
At any point in the program, the value of the variable can be changed.
Lastly, there are guidelines that follow naming variables (depending on the programming language).
Examples of accepted variable names (in C++) are:
num, num_1, num1
Assignment operator
This is the = sign. It is used for assigning values to variables.
Examples of how it is used are:
[tex]num1 = a - b[/tex]
[tex]num\_1 = a*2[/tex]
[tex]num = 4 - 3[/tex]
The following is a wrong usage of the operator
[tex]4 - 3 = num[/tex]

You are calculating commissions for sales staff at work. Employees receive ten dollars for every item sold. Your boss also wants to know the grand total paid to all employees as commission. How would you set this up in an Excel workbook and would you use absolute references, relative references, or both?
Answer:
To find the grand total paid to all employees as commission, we note the following;
The amount received by employees as commission for each item sold, r = $10.00
The information the boss wants to know = The grand total paid to all employees as commission
Let 'n' represent the the total sales, we have;
The grand total commission = Total sales × Commission
1) On MS Excel, four columns are created, labelled, Serial number, Employee Name, Number of Items Sold, Commission
2) In the second row, in the cell under the Commission column heading, Input the formula '=(Cell reference of adjacent Number of Items Sold) × 10' in the cell
3) Copy the the above formula to all the cells in the Commission column by clicking on the cell containing the formula, moving the mouse to the bottom right corner of the cell, and when the mouse pointer changes to a cross sign, left click and hold and drag to all the cells in the column
4) Input the formula =SUM(Argument) in the blank cell below the created Commission list
Where;
Argument = The reference to the range of cells containing the values in the Commission column
5) The output of the =SUM formula is the grand total paid to employees as commission

Find the check digit for the ISBN 978147180930
The check digit is 9
Explanation:
An ISBN (International Standard Book Number) is a 10- or 13-digit number used to uniquely identify a book.
The ISBN contains a very important digit called the check digit.
The check digit of an ISBN is very important as it helps in preventing errors in transmission.
When an ISBN is entered into an ISBN reader, the check digit of the ISBN is compared with the check digit calculated from the other digits of the ISBN. If these two digits match, then there is very high chance that the ISBN is correctly entered.
For example, if an ISBN, say, 9781681972718 is entered into the reader,
i. the inputted check digit is the last digit which is 8
ii. the calculated check digit by the reader will also come up with 8.
iii. since the two values match, then the ISBN has actually been entered correctly.
If however, the entered ISBN number was 9781861972718, then,
i. the inputted check digit is the last digit which is 8
ii. the calculated check digit by the reader will also come up with 2.
iii. since the two values do not match, then the ISBN has actually been entered incorrectly.
To calculate the check digit of an ISBN, the steps are;
i. The first 12 digits of the number are taken.
In our case,
the digits are: 978147180930
ii. Multiply the first digit by 1, the second by 3, the third by 1, the fourth by 3 ... in that format until the twelfth digit which will obviously be multiplied by 3.
9 x 1 = 9
7 x 3 = 21
8 x 1 = 8
1 x 3 = 3
4 x 1 = 4
7 x 3 = 21
1 x 1 = 1
8 x 3 = 24
0 x 1 = 0
9 x 3 = 27
3 x 1 = 3
0 x 3 = 0
iii. Find the sum of the answers in (ii) above
9+21+8+3+4+21+1+24+0+27+3+0 = 121
iv. Find the modulo 10 division of the result in (iii). This is just the remainder when the result is divided by 10.
121 mod 10 = 12 remainder 1
v. If the remainder as calculated in (iv) is zero, then the check digit is 0. If otherwise, subtract the remainder from 10 and the result will be the check digit.
The remainder is 1 which is not zero. Therefore, the check digit is
10 - 1 = 9
The check digit is 9 and
the complete ISBN number will be 9781471809309

Explanation:
Address buses are made up of a collection of wires connecting the CPU with main memory that is used to identify particular locations (addresses) in main memory.
What is CPU?
The electronic equipment that carries out the instructions included in a computer program is known as a central processing unit (CPU), sometimes known as a central processor, main processor, or simply processor.
The CPU executes fundamental mathematical, logical, controlling, and input/output (I/O) activities as directed by the program's instructions. In contrast, specialized processors like graphics processing units and external components like main memory and I/O circuitry (GPUs).
Although CPUs' shape, design, and implementation have evolved throughout time, their basic function has remained mostly same. The arithmetic-logic unit (ALU), which performs arithmetic and logic operations, processor registers.
Therefore, Address buses are made up of a collection of wires connecting the CPU with main memory that is used to identify particular locations (addresses) in main memory.

Recently mobile phones have been used to pay for goods in stores and supermarkets.
One methodof payment involves holding the phone close to a reader in the store.Discuss the advantages and disadvantages of this method of payment compared with other methods of credit/debit card transactions.
Answer:
The advantages of using mobile phones to pay for goods in stores are;
1) The ability to pay for goods and/or services without having to carry a physical wallet, thereby making payments faster, more convenient, and safer as the contents of a money wallet or purse cannot be seen
2) The generation of security codes for each transactions, the use of PIN input and finger sprint scanning for payment, ensures access to payment authorization is limited and requires definitive authentication and that payment transactions will not need to be scrutinized by merchants to detect fraudulent transactions
3) Paying with the mobile phone increases privacy as the card used for payment will be known only to the person doing the payment, thereby a person can use a credit card with low limit without displaying them
The disadvantages of using mobile phones to pay for goods in stores includes;
1) The possibility of breach in security of the mobile phone during payment. Sensitive information of the mobile phone can be collected during payment and then used in other places without the permission of the owner of the phone
2) Mobile phone payment may not be suitable to people who prefer card or cash payment
3) The different mobile phone payment applications and platforms are not entirely compatible and can lead to payment challenges
