Answer:
strVar.replace(pos, n, str);
Explanation:
The strVar.replace() is a javascript function of searching and replacing a string for a defined value, whereby it finds and returns a new string where the defined values are replaced.
For example: to return a string where "Trump" is replaced with "Biden":
We have
var str = "Welcome Trump!";
var res = str.replace("Trump", "Biden", str);
Hence, in this case, the correct answer is strVar.replace(pos, n, str);
Retail products are identified by their Universal Product Codes (UPCs). The most commonform of a UPC has 12 decimal digits: The first digit identifies the product category, the nextfive digits identify the manufacturer, the following five identify the particular product, andthe last digit is acheck digit. The check digit is determined in the following way:
• Beginning with the first digit multiply every second digit by 3.
• Sum all the multiplied digits and the rest of the digits except the last digit.
• If the (10 - sum % 10) is equal to the last digit, then the product code is valid.
• Otherwise it is not a valid UPC.The expression is:sum= 3.x1+x2+ 3.x3+x4+ 3.x5+x6+ 3.x7+x8+ 3.x9+x10+ 3.x11where the x’s are the first 11 digits of the code.
If you choose to add the last digit also in the second step and if the sum is a multiple of 10,then the UPC is valid. Either way, you still need to perform the modular division to checkwhether the given number is a valid code.In this problem, you need to use either a string or long long integer type for the product codebecause it is 12 digits long. If you use string, you can convert one character substring of thestring in to a single digit integer from left to right using the function stoi(str.substr(i,1)).This way you do not need to get last digit of the number and then divide the number by 10.

Translate the following pseudocode for randomly permuting the characters in a string into a C++ program. Read a word. repeat word.length() times Pick a random position i in the word, but not the last position. Pick a random position j > i in the word. swap the letters at positions j and i. Print the word. Please work on this problem after we learn to generate random numbers in the class which is on Wednesday the latest. These problems only deal with simple loop while, for and do loops. You will get a second set of problems next week on nested loops.
Answer:
#include <iostream>
#include <cmath>
using namespace std;
int main(){
string upc;
char last;
cout<< "Enter UPC number: ";
cin >> upc;
if (upc.size() == 12){
last = upc[-1];
} else{
return 0;
}
cout<< last;
char myArr[upc.length()];
for (int i = 0 ; i < upc.substr(0,11).length(); ++i){
if (upc[i]%2 != 0){
myArr[i] = upc[i] * 3;
}
else{
myArr[i] = upc[i];
}
}
int sum = 0;
for (int x = 0; x < sizeof(myArr); ++x){
sum += (int)myArr[x] - '0';
}
if (sum% 10 == last){
cout<<"UPC number is valid";
}
else{
cout<<"Invalid UPC number.";
}
}
Explanation:
The UPC number in the c++ source code input must be 12 digits long for the rest of the code to execute. The code checks the validity of the number by comparing the reminder of the sum division with the last digit in the UPC number.

what product and service type should I choose in quickbooks online if I do not want to track inventory
Answer:
is that what you're looking for
In QuickBooks Online, it’s easy to track how much you make and spend on each product or service. You can also enter these products and services you sell as items so you can quickly add them to sales forms. This gives you more detailed financial reports and helps you complete transactions faster.
Here's how to add services and products you don't plan to track inventory for (also known as non-inventory items).
Note: If you want to track product quantities, add them as inventory items instead.
Answer:
Non-inventory: Products or items you buy or sell, but don't need to track quantities. For example, nuts and bolts you use for installation jobs but don't sell directly.

Explanation:
Consider a distributed denial of service (DDOS) attack, Assume the attacker has compromised a number of broadband connected computers to use as zombie systems. If the ISP provides a maximum uplink data rate of 512 Kbps in ADSL, what is the maximum number of 512-byte ICMP echo request (ping) packets a single zombie computer can send per second? How many such zombie systems would the attacker need to flood a target server in an organization that has
a. A Fast Ethernet.
b. A Gigabit Ethernet.
Answer:
A ) 200 Zombie systems
B ) 200 Zombie systems
Explanation:
maximum uplink data rate : 512 kbps = 512 * 1000 * 8 = 4096000 bits/sec
Determine the number of 512 byte ICMP echo packets = 512 * 8 = 4096 bits
hence the maximum number of 512-byte ICMP echo request (ping) packets a single zombie computer can send per second = 400 packets/sec
i.e. for 512kbps = 400 packets/sec
Determine the number of Zombie systems that the attacker will need to flood a target server
A) For a fast ethernet
A fast ethernet = 100 mbps
The number of Zombie systems needed = 1 zombie system * 200
and 1 zombie system = 512 kbps
therefore for a Fast ethernet the number of zombies systems needed = 200
B) For A Gigabit Ethernet
same as a fast ethernet system i.e. = 200
Clyde Clerk is reviewing his firm’s expense reimbursement policies with the new salesperson, Trav Farr. "Our reimbursement policies depend on the situation. You see, first we determine if it is a local trip. If it is, we only pay mileage of 18.5 cents a mile. If the trip was a one-day trip, we pay mileage and then check the times of departure and return. To be reimbursed for breakfast, you must leave by 7:00 a.m., lunch by 11:00 a.m., and have dinner by 5:00 p.m. To receive reimbursement for breakfast, you must return later than 10:00 a.m., lunch later than 2:00 p.m., and have dinner by 7:00 p.m. On a trip lasting more than one day, we allow hotel, taxi, and airfare, as well as meal allowances. The same times apply for meal expenses." Write structured English for Clyde’s narrative of the reimbursement policies. Draw a decision tree.
Answer:
The answer is described in the image.
Explanation:
The firm is responsible for all expenses made by it's employees, so for a local trip, the cost of gas relative to the mileage covered during the journey is paid for ( 18 cents per mileage).
If it is not a local trip, then it is a one-day trip, so the firm pays for the mileage and the cost of the meals not taken in the company, which depends on the departure and return/arrival time. If the departure and return time is 7am to 10am, the employee is paid for breakfast, if the departure and return is 11am to 2pm then the employee is paid for lunch, and for dinner, 5pm to 7pm.

Which statement is true? A. Pseudocode uses shapes such as rectangles and diamonds to plan a program. B. You only use comments for pseudo code. C. A flowchart uses comments that can be kept as a permanent part of a program. D. A comment line begins with # Please hurry also you can only choose one answer so idk which one thank you
Answer:
D) A comment line begins with #
Explanation:
Comments are used in programming to explain what a line or block of code is doing.
It helps the programmer easily remember what their code was about when they come back to it having left it for a while.
Also comments help other programmers understand code written by one programmer.
A comment or an in-line comment usually begins with #. That way the computer skips it and doesn't regard it as a line of code.
Answer: D. A comment line begins with #.
Explanation:
In the text, it stated, "The easiest way to add a comment is to start the line with the pound sign (#)."
(Comments are notes that allow you to write anything without affecting the code itself. Comments can be utilized to indicate when and how you later changed a program, and provide a description of the changes.)

Armstrong Numbers Programming challenge description: An Armstrong number is an n-digit number that is equal to the sum of the nth powers of its digits. Determine if the input numbers are Armstrong numbers. Input: Your program should read lines from standard input. Each line has a positive integer. Output: Print out True if the number is an Armstrong number, or False if not. Test 1 Test Input 351 Expected Output False
Answer:
Written in Python
number = int(input("Enter a number: "))
computesum = 0
lent = len(str(number))
for digit in str(number):
computesum += int(digit)**lent
if number == computesum:
print("true")
else:
print("false")
Explanation:
This line prompts user for Input input
number = int(input("Enter a number: "))
This line initialises the sum of the nth power of the digits to 0
computesum = 0
This line gets the length of input (i.e. number of digits)
lent = len(str(number))
The following iteration iterates through the digit to check for Armstrong numbers
for digit in str(number):
computesum += int(digit)**lent
This checks if the input number equals the computed sum
if number == computesum:
print("true") --- if yes, "true" is printed
else:
print("false") --- if otherwise, "false" is printed

Explain why the expected value of an F ratio is 1.00 when the null hypothesis is true if there is no treatment effect the numerator.
Answer:
The reason is that the f ratio is balanced due to the numerator and denominator having equal sources of variability.
Explanation:
The expected value of an F ratio is 1.00 when the null hypothesis is true because in a scenario where there is no treatment effect, we have both the numerator and the denominator of the F ratio both measuring equal sources of variability.
Whenever this happens then the F ratio will be balanced and also it will have a value that is near 1.00.
If process P0 is switched to process P1, state for P0 will be saved into ____, and state from ___ will be reloaded.
Answer:
1. PCB0
2. PCB1
Explanation:
Given that PCB is often referred to as Process Control Block, is a form of data structure that is applicable and utilized by the computer operating systems to store all the information concerning a process.
This process is carried out in a way that when Process P0 is initialized, the operating system established a related process that takes the computer processing unit from Process P0 and allocates it to Process P1, the Operating System, in turn, will save P0's PCB, and then reload P1's PCB.
Hence, If process P0 is switched to process P1, the state for P0 will be saved into "PCB0" and the state from "PCB1" will be reloaded.

What is rhymeWord?Rhyming words all have the same last consonant. Simply put, it is the repetition of similar sounds. When two words have similar sounds, usually those that follow the final stressed syllable of each word, the words are said to rhyme. Cat-hat, rotten-forgotten, and heard-bird are some examples of words that rhyme; they all have similar sounds after the final stressed syllable.
If the last sounds of two or more words are the same or similar, then the words will rhyme. Some words that rhyme are goat, boat, moat, float, and coat. To determine whether two words rhyme, use your ears to listen while you speak the words. If two words have a similar or matching sound, they rhyme.
Thus, option C is correct.
