- 6. In Java, you have the opportunity to either use a predefined function/method or write a user-defined function/method. In this discussion, provide at least three criteria that would be used to develop an appropriate method of your choice and the rationale behind the selection of these criteria.In most compiled programming languages, variables are "typed," meaning that you have to declare them as integers, characters. etc.. Is that the case with JavaScript? Name one pro and one con of variable type declarations.ALL DONE IN PYTHON PLEASE!!!! In many businesses across the country, people are buying food and goods using cash. Whenever a purchase is made with cash, it is usual that change must be back to the customer. Business point of sales software help to ensure that the correct change is return to a customer by providing detailed information of the change that should be returned to the customer. using the fewest number of bills and coins. In this assignment, you are asked to use what we have covered in Modules 1-3 to design and implement a program that writes out what bills (ones, fives, tens, twenties) and coins (pennies, nickels, dimes, and quarters) that should be returned to the customer given two inputs from the user: A total cost of a sale. The amount that was paid by the customer. Ensure that your output is grammatically correct. If the customer does not provide adequate payment, you should print the following statement, the program should end. Did not receive enough cash from the…
- Complete the following questions about different types of variables:i. Check the last digit of your id number(123456789). If it is even or 0, fill the gap in (A)with the word global (i.e., static global), otherwise, fill it with local (i.e., static local).Then, complete Table I. ii. In a multi-source program, there is a fileA.c that contains variables and functions,and a fileB.c that contains the main function, as well as usage of some of theresources found in fileA.c. Explain:a) fileA.c has a global variable called my_variable, that should only beaccessed within the file. I.e., no other files should be able to access thatvariable.How should my_variable be declared inside of the file, in order to guaranteethis functionality? b) fileA.c also has a global variable called my_shared_variable, which canand should be accessible from other files, including fileB.c.How should my_shared_variable be declared in order to allow thisfunctionality?Note for item ii): You also need to state in a…Create a class calculate that uses two separate functions:-a function to multiply two float numbers and another to divide two float numbers using the concept of inline function. Also, create a method to print the result on the screen. solve in c++Local declarations are those that are kept in the memory of the computer; but, how exactly are they kept in memory? If reaching one's objective can be done without making use of local declarations, then doing so is a waste of time. Why bother using value parameters when you can just use references as your arguments in any function? How crucial are value parameters when it comes to the processing of programmed data?
- The Java code must have the structure as shown in the picture and pay attention to which outputs should be shown for some example inputs: Develop with Java programming language a calculator (console application) that takes a number, a basic math operator ( + , - , * , / , % ), and a second number all from user input, and have it print the result of the mathematical operation. The mathematical operations should be wrapped inside of functions. Note: Do please use the provided source code template to implement your solution. The purpose of this problem is not only to assess the students' ability to build a valid implementation but also to assess the ability to read the Java code. Input: On single line a number, a basic math operator ( + , - , * , / , % ), and a second number all from user input. Output: On new line result of the mathematical operation. In the case of "Division by zero" you must printout the text message "Error".

- For the question below how can I concatenate using and object like append()? for the pseudocode section 3 and code below. thank you Please provide the function or module header in in c++ code for each of the following. Include comments that describe the parameters and return values (if a value is returned). Do not define the function, just give the header or prototype and comments. Be sure to indicate if the parameters need to be passed by reference. 1. Swaps two reals. 2. Calculates and returns the sales tax of 8.25 given the price and the amount of the tax rate (both as reals). 3. Returns the concatenation of two strings. 4.

Some of the logic hasbeen filled out for you in the email.py file.● Open the file called email.py.● Create a class definition for an Email which has four variables:has_been_read, email_contents, is_spam and from_address.● The constructor should initialise the sender’s email address.● The constructor should also initialise has_been_read and is_spam to false.● Create a function in this class called mark_as_read which should changehas_been_read to true.● Create a function in this class called mark_as_spam which should changeis_spam to true.● Create a list called inbox to store all emails (note that you can have a list ofobjects).● Then create the following methods:○ add_email - which takes in the contents and email address from thereceived email to make a new Email object.○ get_count - returns the number of messages in the store.○ get_email - returns the contents of an email in the list.
