Explanation:
Write a program that will perform a few different String operations. The program must prompt for a name, and then tell the user how many letters are in the name, what the first letter of the name is, and what the last letter of the name is. It should then end with a goodbye message. A sample transcript of what your program should do is below:
Enter your name: Jeremy
Hello Jeremy!
Your name is 6 letters long.
Your name starts with a J.
Your name ends with a y.
Goodbye!
Answer:
Follows are the code to this question:
import java.util.*;//import package for user input
public class Main//defining a class Main
{
public static void main(String[] asp)//main method
{
String n;//defining String variable
Scanner oxr=new Scanner(System.in);//creating Scanner class Object
System.out.print("Enter your name: ");//print message
n=oxr.next();//input value
System.out.println("Hello "+n+"!");//print message with value
System.out.println("Your name is "+n.length()+" letters long.");//print message with value
System.out.println("Your name starts with a "+n.charAt(0)+".");//print message with value
System.out.println("Your name ends with a "+n.charAt(n.length()-1)+".");//print message with value
System.out.print("Goodbye!");//print message
}
}
Output:

Explanation:
In the above-given code, A string variable "n" is declared, that uses the Scanner class object for input the value from the user-end.
In the next step, the multiple print method has used, which calculates the length, first and the last latter of the string value, and uses the print method to print the calculated value with the given message.
You've created a new programming language, and now you've decided to add hashmap support to it. Actually you are quite disappointed that in common programming languages it's impossible to add a number to all hashmap keys, or all its values. So you've decided to take matters into your own hands and implement your own hashmap in your new language that has the following operations:
insert x y - insert an object with key x and value y.
get x - return the value of an object with key x.
addToKey x - add x to all keys in map.
addToValue y - add y to all values in map.
To test out your new hashmap, you have a list of queries in the form of two arrays: queryTypes contains the names of the methods to be called (eg: insert, get, etc), and queries contains the arguments for those methods (the x and y values).
Your task is to implement this hashmap, apply the given queries, and to find the sum of all the results for get operations.
Example
For queryType = ["insert", "insert", "addToValue", "addToKey", "get"] and query = [[1, 2], [2, 3], [2], [1], [3]], the output should be hashMap(queryType, query) = 5.
The hashmap looks like this after each query:
1 query: {1: 2}
2 query: {1: 2, 2: 3}
3 query: {1: 4, 2: 5}
4 query: {2: 4, 3: 5}
5 query: answer is 5
The result of the last get query for 3 is 5 in the resulting hashmap.
For queryType = ["insert", "addToValue", "get", "insert", "addToKey", "addToValue", "get"] and query = [[1, 2], [2], [1], [2, 3], [1], [-1], [3]], the output should be hashMap(queryType, query) = 6.
The hashmap looks like this after each query:
1 query: {1: 2}
2 query: {1: 4}
3 query: answer is 4
4 query: {1: 4, 2: 3}
5 query: {2: 4, 3: 3}
6 query: {2: 3, 3: 2}
7 query: answer is 2
The sum of the results for all the get queries is equal to 4 + 2 = 6.

In the following code segment, assume that the ArrayList numList has been properly declared and initialized to contain the Integer values [1, 2, 2, 3]. The code segment is intended to insert the Integer value val in numList so that numList will remain in ascending order. The code segment does not work as intended in all cases.
int index = 0;
while (val > numList.get(index))
{
index++;
}
numList.add(index, val);
For which of the following values of val will the code segment not work as intended?
a. 0
b. 1
c. 2
d. 3
e. 4
Answer:
e. 4
Explanation:
The code segment will not work as intended if the value of the variable val is 4. This is because the while loop is comparing the value of the variable val to the value of each element within the numList. Since there is no element that is bigger than or equal to the number 4, this means that if the variable val is given the value of 4 it will become an infinite loop. This would cause the program to crash and not work as intended.
The program illustrates the use of while loops.
The code segment will not work as intended when the value of val is 4
LoopsLoops are used to perform repeated operations
The programFrom the program, the while loop is repeated under the following condition:
val > numList.get(index)
This means that:
The loop is repeated as long as val has a value greater than the index of numList (i.e. 3)
From the list of options, 4 is greater than 3.
Hence, the code segment will not work as intended when the value of val is 4

Explanation:
In this programming assignment, you will write a simple program in C that outputs one string. This assignment is mainly to help you get accustomed to submitting your programming assignments here in zyBooks. Write a C program using vim that does the following. Ask for an integer input from the user. Do not print any prompt for input. If the number is divisible by 3, print the message CS If the number is divisible by 5, print the message 1714 If the number is divisible by both 3
Answer:
In C:
#include <stdio.h>
int main() {
int mynum;
scanf("%d", &mynum);
if(mynum%3 == 0 && mynum%5 != 0){
printf("CS"); }
else if(mynum%5 == 0 && mynum%3 != 0){
printf("1714"); }
else if(mynum%3 == 0 && mynum%5 == 0){
printf("CS1714"); }
else {
printf("ERROR"); }
return 0;
}
Explanation:
This declares mynum as integer
int mynum;
This gets user input
scanf("%d", &mynum);
This condition checks if mynum is divided by 3. It prints CS, if true
if(mynum%3 == 0 && mynum%5 != 0){
printf("CS"); }
This condition checks if mynum is divided by 5. It prints 1714, if true
else if(mynum%5 == 0 && mynum%3 != 0){
printf("1714"); }
This condition checks if mynum is divided by 3 and 5. It prints CS1714, if true
else if(mynum%3 == 0 && mynum%5 == 0){
printf("CS1714"); }
This condition checks if num cannot be divided by 3 and 5. It prints ERROR, if true
else {
printf("ERROR"); }

A perpetual system of inventory can be defined as a method of financial accounting, which involves the updating informations about an inventory on a continuous basis (in real-time) as the sales or purchases are being made by the customers, through the use of enterprise management software applications and a digitized point-of-sale (POS) equipment.
Under a perpetual system of inventory, updates of the journal entry for cost of goods sold or received would include debiting accounts receivable and crediting sales immediately as it is being made or happening.
Hence, an advantage of the perpetual system of inventory over the periodic system of inventory is that, it ensures the inventory account balance is always accurate provided there are no spoilage, theft etc.
The following are the characteristic of a perpetual inventory system;
I. It is the most popular choice for modern business.
II. Inventory is updated in near real-time.
III. It provides up-to-date balance information and requires fewer physical counts.

What is the relationship between an object and class in an OOP program?
The object contains classes.
The object and class are the same thing.
The object is used to create a class.
The object in a program is called a class.
Answer:
D. The object in a program is called a class.
Explanation:
Java is a object oriented and class-based programming language. It was developed by Sun Microsystems on the 23rd of May, 1995. Java was designed by a software engineer called James Gosling and it is originally owned by Oracle.
In object-oriented programming (OOP) language, an object class represents the superclass of every other classes when using a programming language such as Java. The superclass is more or less like a general class in an inheritance hierarchy. Thus, a subclass can inherit the variables or methods of the superclass.
Basically, all instance variables that have been used or declared in any superclass would be present in its subclass object.
Hence, the relationship between an object and class in an OOP program is that the object in a program is called a class.
For example, if you declare a class named dog, the objects would include barking, color, size, breed, age, etc. because they are an instance of a class and as such would execute a method defined in the class.

g n this program, you will prompt the user for three numbers. You need to check and make sure that all numbers are equal to or greater than 0 (can use an if or if/else statement for this). You will then multiply the last two digits together, and add the result to the first number. The program should then start over, once again asking for another three numbers. This program should loop indefinitely in this way. If the user enters a number lower than 0, remind the user that they need to enter a number greater than or equal to 0 and loop the program again.
Answer:
In Python:
loop = True
while(loop):
nm1 = float(input("Number 1: "))
nm2 = float(input("Number 2: "))
nm3 = float(input("Number 3: "))
if (nm1 >= 0 and nm2 >= 0 and nm3 >= 0):
result = nm2 * nm3 + nm1
print("Result: "+str(result))
loop = True
else:
print("All inputs must be greater than or equal to 0")
loop = True
Explanation:
First, we set the loop to True (a boolean variable)
loop = True
This while loop iterates, indefinitely
while(loop):
The next three lines prompt user for three numbers
nm1 = float(input("Number 1: "))
nm2 = float(input("Number 2: "))
nm3 = float(input("Number 3: "))
The following if condition checks if all of the numbers are greater than or equal to 0
if (nm1 >= 0 and nm2 >= 0 and nm3 >= 0):
If yes, the result is calculated
result = nm2 * nm3 + nm1
... and printed
print("Result: "+str(result))
The loop is then set to true
loop = True
else:
If otherwise, the user is prompted to enter valid inputs
print("All inputs must be greater than or equal to 0")
The loop is then set to true
loop = True

# this prints the name and prices of each item from the list.
Write a function called is_present that takes in two parameters: an integer and a list of integers (NOTE that the first parameter should be the integer and the second parameter should be the list) and returns True if the integer is present in the list and returns False if the integer is not present in the list. You can pick everything about the parameter name and how you write the body of the function, but it must be called is_present. The code challenge will call your is_present function with many inputs and check that it behaves correctly on all of them. The code to read in the inputs from the user and to print the output is already written in the backend. Your task is to only write the is_present function.
Answer:
The function in python is as follows
def is_present(num,list):
stat = False
if num in list:
stat = True
return bool(stat)
Explanation:
This defines the function
def is_present(num,list):
This initializes a boolean variable to false
stat = False
If the integer number is present in the list
if num in list:
This boolean variable is updated to true
stat = True
This returns true or false
return bool(stat)
