Value is always _____________ aligned in a cell. ​

Refer to the explanation provided. In the online shopping software system, five actors can be identified: A Customer can perform actions such as exploring products and seeking product information. The interface allows for the creation of customer accounts facilitating purchases. Additionally, customers can browse items by using search categories or keywords, and they are able to order and make payments for their selected products. The payment system accepts two primary methods: credit card and PayPal. A Seller can list products in appropriate categories and create accounts to gain membership. An Administrator manages product listings and can modify existing categories or introduce new ones. Finally, the Site Manager has the capability to view different reports regarding customer orders, seller-added products, and user-created accounts.

The correct option is c) abstract class A { abstract void unfinished(); }. In order for a class to be considered a legal abstract class, it must include the keyword 'abstract' designated before the class name, and additionally, the abstract functions must also incorporate the 'abstract' keyword alongside a void return type.

Answer:

Below is the month_days function:

def month_days(month, days):

 print (month +" has " + str(days) + " days.")

You can invoke this function with arguments like:

month_days ("June", 30)

month_days("July", 31)

The function can also be restructured as follows:

def month_days(month, days):

 return (month +" has " + str(days) + " days.")

To view the output, call the function along with print like this:

print(month_days ("June", 30))

print(month_days("July", 31))

Explanation:

The defined month_days function takes two parameters: the month name and the number of days in that month. It has a return statement return (month +" has " + str(days) + " days.") which combines the month name held in the variable month with the word "has" and then the number of days stored in days followed by the term days.

For instance, if "June" is passed in as month and 30 as days, the output will be:

June has 30 days.

This program can also be constructed using an f-string for better formatting in the month_days function:

def month_days(month, days):

   output = f"{month} has {days} days."

   return (output)

To see the output, invoke the function with print:

print (month_days("June", 30))

print (month_days("July", 31))

The f-string starts with 'f' and includes the parameters month and days within curly braces. The variables month and days are substituted with their respective values when the function is called.

Screenshot of the program and its output is attached.

Answer:

int withinArray(int * intArray, int size, int * ptr) {

      if(ptr == NULL) // if ptr is NULL return 0

            return 0;

      // if the size of intArr is zero

      if(size == 0)

          return 0; // not found

  else  

          {

            if(*(intArray+size-1) == *(ptr)) // check if (size-1)th element equals ptr

                   return 1; // return positive indication

            return withinArray(intArray, size-1,ptr); // call function recursively with size-1 elements

         }

}

Explanation:

This is the complete part of the program.

The code is implemented using the Java programming language. This program effectively calculates the distance between two points based on the formula provided.
