A program in Python that asks the user for 10 numbers and determines the total count of even and odd numbers is given below.

Program:

even_count = 0

odd_count = 0

for i in range(10):

   number = int(input("Enter number: "))

   if number % 2 == 0:  # Check if the number is even

       even_count += 1

   else:

       odd_count += 1

print("Total even numbers:", even_count)

print("Total odd numbers:", odd_count)

In this program, we use a for loop to iterate 10 times, asking the user to enter a number in each iteration.

We then check whether the number is even by using the modulo operator % to check if the remainder of dividing the number by 2 is zero. If it is, we increment the even_count variable; otherwise, we increment the odd_count variable.

After the loop completes, we print the total count of even and odd numbers.

Using an external style sheet is always better for readability and maintainability.

External style sheets can be referenced and reused by many different pages. A local <style> tag could be used on each .html document, but this would mean that any CSS changes made would need to be updated within each style tag, on each .html document. By putting it onto an external style sheet, you only need to update the CSS in one location for it to be used throughout the website.

In a relational database, a primary key is a unique identifier for each record in a table. It ensures that each record can be identified uniquely and that there are no duplicates. On the other hand, a foreign key is a field in one table that refers to the primary key in another table. It establishes a link between the two tables.

To identify the primary keys and foreign keys in three tables, we first need to examine the structure of each table. We can then determine which columns in each table are the primary keys and foreign keys.

Table 1: Customers
- Primary Key: CustomerID
- Foreign Key: None

Table 2: Orders
- Primary Key: OrderID
- Foreign Key: CustomerID

Table 3: OrderDetails
- Primary Key: OrderDetailID
- Foreign Key: OrderID

In Table 1, the primary key is CustomerID, which is a unique identifier for each customer record. Since there are no references to this column in any other tables, it is not a foreign key.

In Table 2, the primary key is OrderID, which is a unique identifier for each order record. The foreign key is CustomerID since it refers to the primary key in the Customers table.

In Table 3, the primary key is OrderDetailID, which is a unique identifier for each order detail record. The foreign key is OrderID since it refers to the primary key in the Orders table.

Overall, understanding primary and foreign keys is essential for creating and maintaining a well-designed database. By using primary and foreign keys appropriately, we can ensure that data is organized efficiently and accurately.

Below is an example of an Apex class that returns an array (or list) of strings.

public class StringArrayExample {

   public static List<String> getStringArray() {

       List<String> strings = new List<String>();

       strings.add("Hello");

       strings.add("World");

       strings.add("OpenAI");

       return strings;

   }

}

The given example demonstrates an Apex class named StringArrayExample that contains a method called getStringArray(). This method returns a list of strings (List<String>).

Within the method, a new list of strings is created using the List<String> data type. Three strings, "Hello", "World", and "OpenAI", are added to the list using the add() method. Finally, the list of strings is returned using the return statement.

To utilize this class and retrieve the array of strings, you can instantiate the StringArrayExample class and call the getStringArray() method. This will return a list containing the strings "Hello", "World", and "OpenAI". You can then use this list in your Apex code as needed.

Answer:

I am writing a Python program. Let me know if you want the program in some other programming language.

def toCamelCase(str):  

   string = str.replace("-", " ").replace("_", " ")  

   string = string.split()

   if len(str) == 0:

       return str

   return string[0] + ''.join(i.capitalize() for i in string[1:])

print(toCamelCase("the-stealth-warrior"))

Explanation:

I will explain the code line by line. First line is the definition of  toCamelCase() method with str as an argument. str is basically a string of characters that is to be converted to camel casing in this method.

string = str.replace("-", " ").replace("_", " ") . This statement means the underscore or dash in the entire are removed. After removing the dash and underscore in the string (str), the rest of the string is stored in string variable.  

Next the string = string.split()  uses split() method that splits or breaks the rest of the string in string variable to a list of all words in this variable.

if len(str) == 0 means if the length of the input string is 0 then return str as it is.

If the length of the str string is not 0 then return string[0] + ''.join(i.capitalize() for i in string[1:])  will execute. Lets take an example of a str to show the working of this statement.

Lets say we have str = "the-stealth-warrior". Now after removal of dash in by replace() method the value stored in string variable becomes the stealth warrior. Now the split() method splits this string into list of three words the, stealth, warrior.

Next return string[0] + ''.join(i.capitalize() for i in string[1:])  has string[0] which is the word. Here join() method is used to join all the items or words in the string together.

Now i variable moves through the string from index 1 and onward and keeps capitalizing the first character of the list of every word present in string variable from that index position to the end.  capitalize() method is used for this purpose.

So this means first each first character of each word in the string starting from index position 1 to the end of the string is capitalized and then all the items/words in string are joined by join() method. This means the S of stealth and W of warrior are capitalized and joined as StealthWarrior and added to string[0] = the which returns theStealthWarrior in the output.

Fields are the components that provide structure for a table. Fields in a table store the same category of data in the same data type. For example, if you have a NAME field in a table of customers, the entries for this field are all customer names and are stored as text.

A primary key is a field or set of fields with values that are unique throughout a table. Values of the key can be used to refer to entire records, because each record has a different value for the key. Each table can only have one

primary key.

The primary key of this table is the ISBN, which uniquely identifies a book. The title column relates to the book; this is the title of the book. Each row of this table is about one book.

   for i in range(len(a)):

       tot = tot + a [i]

   return tot

arr = []

numbers = int(input("How many values to add to the array:\n"))

buildArray(arr, numbers)

print(arr)

print("Total " + str(sumArray(arr)) )

Explanation:

The program is an illustration of lists

Lists are variables that are used to hold multiple values in one variable name

The program in Python, where comments are used to explain each line is as follows:

#This gets the number of inputs to the array

n = int(input("How many values to add to the array: "))

#This initializes the sum to 0

sumArray = 0

#This initializes a list

myList = []

#This iterates through n

for i in range(n):

   #This gets input for the list elements

   num = int(input())

   #This appends the input to the list

   myList.Append(num)

   #This calculates the sum

When writing code in JavaScript, it is common to use semicolons as a means of dividing individual statements.

Usually, to end a statement in programming, one would use a semicolon at the completion of a line of code. JavaScript has a mechanism known as automatic semicolon insertion (ASI) that allows for the omission of semicolons under specific circumstances, as the interpreter will add them automatically.

If you want to ensure correct syntax and make your code more readable, you can place a semicolon at the end of each line.

An example:

var x = 5;

console.log(x);

In this case, the semicolon is placed after the assignment statement var x = 5; and after the console.log(x); statement.
