Explanation:
Using a text editor, create a file that contains a list of at least 15 six-digit account numbers. Read in each account number and display whether it is valid. An account number is valid only if the last digit is equal to the remainder when the sum of the first five digits is divided by 10. For example, the number 223355 is valid because the sum of the first five digits is 15, the remainder when 15 is divided by 10 is 5, and the last digit is 5. Write only valid account numbers to an output file, each on its own line. Save the application as ValidateCheckDigits.java.
Answer:
Explanation:
The following code is written in Java. It reads every input and checks to see if it is valid. If it is it writes it to the output file.

Write a recursive method named factorial that accepts an integer n as a parameter and returns the factorial of n, or n!. A factorial of an integer is defined as the product of all integers from 1 through that integer inclusive. For example, the call of factorial(4) should return 1 * 2 * 3 * 4, or 24. The factorial of 0 and 1 are defined to be 1. You may assume that the value passed is non-negative and that its factorial can fit in the range of type int. Do not use loops or auxiliary data structures; solve the problem recursively.
Answer:
The function in Python is as follows:
def factorial(n):
if n == 1 or n == 0:
return n
else:
return n*factorial(n-1)
Explanation:
This defines the function
def factorial(n):
This represents the base case (0 or 1)
if n == 1 or n == 0:
It returns 0 or 1, depending on the value of n
return n
If n is positive, then this passes n - 1 to the factorial function. The process is repeated until n = 1
else:
return n*factorial(n-1)

This is usually an issue with the Microsoft Visual C++ redistributable. One fix that usually works is to do the following
Open Programs and Features
Uninstall and then choose Repair on Microsoft Visual C++ Redistributable (x86) and x64 version
Reinstall or repair the installation of the .NET Core SDK 1.0.1.
If this does not work, another option would be to manually change the install path of these files from "Program Files (x86) to "Program Files"

CS160 Computer Science I In class Lab 10
Objective:
Work with dictionaries
Work with strings
Work with files
Assignment:
This program will read a file of English words and their Spanish translation. It then asks the user for an English word. If it exists in your dictionary the Spanish translation is displayed. If the English word does not exist in the dictionary the program states that the word does not exist in its list of words.
Specifics:
Create a text file, with one English word and a Spanish word per line, separated by a colon. You can create the language file using a text editor, you do not need to write a program to create this file. An example of the file might be:
one:uno
two:dos
three:tres
four:cuatro
five:cinco
six:seis
seven:siete
eight:ocho
nine:nueve
ten:diez
After reading the text file, using it to fill up a dictionary, ask the user for an English word. If the word exists, print out the Spanish version. If the word does not exist state that the word is not in your list. Continue this process of asking for a word until the user does not enter a word (just pressed Enter).
As you might have noticed, there is nothing in the program that limits this Spanish words. This program can be written to work with any translation, so feel free to make it be French, or German or any other language where you can come up with a list of translated words. You also are not limited to 10 words, that is just the list I came up with for the example. The number of key/values pairs that you have in your dictionary is basically limited by the memory in your computer.
Hints
You will need to determine if the key (the English word) exists in the dictionary. Use the in operator with the dictionary, or the get() method. Either can be used to avoid crashing the program, which happens if you attempt to use a key that does not exist.
An example of running the program might be:
Enter the translation file name: oneToTen.txt
> Enter an English word to receive the Spanish translation.
Press ENTER to quit.
Enter an English word: one
he Spanish translation is uno
Enter an English word: ten
The Spanish word is diez
Enter an English word: 5
I don’t have that word in my list.
Enter an English word: three
The Spanish word is tres
Answer:
The program in Python is as follows:
fname = input("Enter the translation file name: ")
with open(fname) as file_in:
lines = []
for line in file_in:
lines.append(line.rstrip('\n'))
myDict = {}
for i in range(len(lines)):
x = lines[i].split(":")
myDict[x[0].lower()] = x[1].lower()
print("Enter an English word to receive the Spanish translation.\nPress ENTER to quit.")
word = input("Enter an English word: ")
while(True):
if not word:
break
if word.lower() in myDict:
print("The Spanish word is ",myDict[word.lower()])
else:
print("I don’t have that word in my list.")
word = input("Enter an English word: ")
Explanation:
This prompts the user for file name
fname = input("Enter the translation file name: ")
This opens the file for read operation
with open(fname) as file_in:
This creates an empty list
lines = []
This reads through the lines of the file
for line in file_in:
This appends each line as an element of the list
lines.append(line.rstrip('\n'))
This creates an empty dictionaty
myDict = {}
This iterates through the list
for i in range(len(lines)):
This splits each list element by :
x = lines[i].split(":")
This populates the dictionary with the list elements
myDict[x[0].lower()] = x[1].lower()
This prints an instruction on how to use the program
print("Enter an English word to receive the Spanish translation.\nPress ENTER to quit.")
This prompts the user for an English word
word = input("Enter an English word: ")
This loop is repeated until the user presses the ENTER key
while(True):
If user presses the ENTER key
if not word:
The loop is exited
break
If otherwise, this checks if the word exists in the dictionary
if word.lower() in myDict:
If yes, this prints the Spanish translation
print("The Spanish word is ",myDict[word.lower()])
If otherwise,
else:
Print word does not exist
print("I don’t have that word in my list.")
Prompt the user for another word
word = input("Enter an English word: ")
State the items that will be examined when performing a binary search for Monkey,
which is not in the list.
The items that will be examined when performing a binary search for monkeys are Antelope, Baboon, Cheetah, Elephant, and Giraffe in the first half of the cycle.
What is binary search?
A search algorithm known as binary search in computer science, also known as half-interval search, logarithmic lookup, or binary chop, asserts to have discovered the location of a target value within a sorted array.
The target value is compared to the middle element of the array using binary search. A successful approach for finding an item in a sorted list of elements is binary search.
Therefore, in the first half of the cycle, the following objects will be looked at when conducting a binary search for monkeys: antelope, baboon, cheetah, elephant, and giraffe.

Create a program which reads in CSV data of Creatures and loads them into aHash Map. The key of this hash map will be the name of each creature. For your hash function, you can simply use the sum of all ASCII values. You can also come up with your own hash function. Your program should present a menu to the user allowing them to look up a creature by name. Additionally, create a function that allows the user to insert a new creature. This creature should be added to the existing hash map. If the name entered by the user already exists, DO NOT ADD IT TO THE HASH MAP. Simply report that the creature already exists. If the creature is unique and successfully added, report the calculated index value. Your hash array should start as size4. You will need to implement a rehashing function to maintain a load factor of 0.75. Collision resolution should be handled via separate chaining with linked lists.
Other Requirements
•Read in a CSV file from the command line when running the program.
•Convert the raw CSV data into the creature struct and add it to a HashMap
•Make sure you properly release all of your allocated memory.
•Format your code consistently.
•Function declarations, structs, and preprocess directives should be placed in a corresponding header file.
•Save your code for this problem ascreature_hash.(c|h).

Counting the character occurrences in a file
For this task you are asked to write a program that will open a file called “story.txt
and count the number of occurrences of each letter from the alphabet in this file.
At the end your program will output the following report:
Number of occurrences for the alphabets:
a was used-times.
b was used - times.
c was used - times .... ...and so, on
Assume the file contains only lower-case letters and for simplicity just a single
paragraph. Your program should keep a counter associated with each letter of the
alphabet (26 counters) [Hint: Use array|
| Your program should also print a histogram of characters count by adding
a new function print Histogram (int counters []). This function receives the
counters from the previous task and instead of printing the number of times each
character was used, prints a histogram of the counters. An example histogram for
three letters is shown below) [Hint: Use the extended asci character 254]:
Answer:
#include <stdio.h>
#include <ctype.h>
void printHistogram(int counters[]) {
int largest = 0;
int row,i;
for (i = 0; i < 26; i++) {
if (counters[i] > largest) {
largest = counters[i];
}
}
for (row = largest; row > 0; row--) {
for (i = 0; i < 26; i++) {
if (counters[i] >= row) {
putchar(254);
}
else {
putchar(32);
}
putchar(32);
}
putchar('\n');
}
for (i = 0; i < 26; i++) {
putchar('a' + i);
putchar(32);
}

int main() {
int counters[26] = { 0 };
int i;

You’ve never seen a need to do any marketing or advertising since you were able to stay profitable without those things. Plus, you lack any real understanding of how to use technology and it makes you anxious just thinking about technology or social media. However, your son just graduated from college and came home to live with you for the summer before he starts his new marketing manager job at a big firm. He tells you that you are probably losing a big share of the market by avoiding technology and social media. He also says that many of these items can be implemented very easily, and he would volunteer to continue to manage the social media sites in his spare time even after he starts his new job.

Answer:
Explanation:
1. Decide what to back up
If you've stored anything valuable on your hard drive , you'll need to back that up yourself.
2. Choose backup media
You'll need to store your backup on a separate form of digital media - such as Go-ogle Drive, One Drive for Business or an external hard drive
3. Back up your data
The backup method will vary depending on your choice of software and operating system Once that's done, schedule regular future backups.
4. Store it safely
You don't want to lose your PC and your backup. So, be smart and keep your backup somewhere safe.
5. Check that it works
Errors and technical glitches can happen without you even noticing. You may only find out later when you actually need to use that data that something went wrong. Avoid the worry by checking your backups once in a while and confirming that the data is being properly backed up.

Answer:
A) Map
Explanation:
All gasoline (petrol) fuel systems need ways or method that will be calculating amount of the air that is entering the engine.This is true as regards mechanical fuel injection, carburetors and electronic fuel injection.Speed density system fall under one of this method. "Speed" in this context means the speed of the engine while "density" means density of the air. The Speed is been measured using the distributor, crankshaft position sensor could be used here. The Density emerge from from measuring of the air pressure which is inside the induction system, using a typical "manifold absolute pressure" (MAP) sensor as well as air temperature sensor. Using pieces of information above, we can calculate
mass flow rate of air entering the engine as well as the correct amount of fuel can be supplied. With this system,
the mass of air can be calculated. One of the drawback if this system is that
Any modification will result to incorrect calculations. Speed-Density can be regarded as method use in estimation of airflow into an engine so that appropriate amount of fuel can be supplied as well as. adequate spark timing. The logic behind Speed-Density is to give prediction of the amount of air ingested by an engine accurately during the induction stroke. Then this information could now be used in calculating how much fuel is required to be provided, This information as well can be used in determining appropriate amount of ignition advance. It should be noted The speed density fuel injection system uses the Map sensor as the primary sensor to determine base pulse width
