This assignment is For a C++ class , I am having difficulty with getting the boolean statements the most; getting them set up properly inside the int main() area.

You have been asked to define a tip-calculating function named calcTip that could be integrated into a larger piece of software designed to improve guest service at a restaurant. As a result, you must conform to the function specification used throughout the rest of the project's code:

double calcTip(double checkAmount, bool postTax, bool round);

This function, when called, calculates and returns a tip amount in U.S. dollars determined by the values of its two boolean parameters. Any extra comments with guidance will be very apprectiated, thank you so much!
----

tipCalc's parameters:

checkAmount:

The amount of a check in U.S. dollars with tax included.
Ex. a value of 15.00 represents $15.00 USD.

postTax:

The value of the postTax parameter determines whether the function calculates a tip before or after the tax has been added to a check amount.

A value of true means that the calculated tip will be based off the entire check amount.

A value of false indicates that tax must be removed from the check amount before a tip is calculated.

round:

The value of the round parameter determines whether or not the tip amount is rounded up before being returned. A value of true indicates that the value will be rounded up.

----

Assume that the tax rate for meals is a fixed 7.8% regardless of the geographical region in which
this software may be used. Also, in the interest of elevating the standard of what constitutes a
good tip, the tip rate is a fixed 20%.

As examples, a tip calculated for an entire $20.00 check (which includes tax) without rounding would be $4.00. A tip calculated for only the pre-tax amount of a $20.00 check without rounding would be $3.69.

Implementation

You must not make any changes to the calcTip's return type or parameters.

----

In main, you must prompt for and accept user input that will be used as arguments for a calcTip function call.

You have the freedom to structure main as you see fit, provided that I can execute your program and specify the following before a call to calcTip is made:

1.) the amount of the check after tax has been applied (e.g. I can enter $20.00 or similar)
2.) whether or not I want my tip to be calculated off the full check (i.e. including tax)
3.) whether or not I want to round up my tip to the nearest U.S. dollar

You must not prompt for this input inside calcTip().

----

Once this is done, a function call to calcTip must be made inside main; its return value
will be output.

Results

Output the following text in main after making the call to calcTip:

Your tip amount is $[TIP AMOUNT]

In order to verify program correctness, you should run the program four times under the following conditions:

1.) The user wants a 20% tip on a $15 check before tax with no rounding.
2.) The user wants a 20% tip on a $15 check after tax with no rounding.
3.) The user wants a 20% tip on a $15 check before tax with rounding.
4.) The user wants a 20% tip on a $15 check after tax with rounding.

Java Beginner

a)Create a class named Student that has fields for an ID number, number of credit hours earned, and number of points earned. (For example, many schools compute grade point averages based on a scale of 4, so a three-credit-hour class in which a student earns an A is worth 12 points.) Include methods to assign values to all fields. A Student also has a field for grade point average. Include a method to compute the grade point average field by dividing points by credit hours earned. Write methods to display the values in each Student field. Save this class as Student.java.

b)Write a class named ShowStudent that instantiates a Student object from the class you created and assign values to its fields. Compute the Student grade point average, and then display all the values associated with the Student. Save the application as ShowStudent.java.

c)Create a constructor for the Student class you created. The constructor should initialize each Student’s ID number to 9999, his or her points earned to 12, and credit hours to 3 (resulting in a grade point average of 4.0).Write a program that demonstrates that the constructor works by instantiating an object and displaying the initial values. Save the application as ShowStudent2.java.

Represent the following numbers in binary 8-bit representation using singed magnitude, one's complement, two's complement, and excess-127 representations:

a) 48

b) -35

I am using NetBeans IDE Java to code and I am seeking comment to the code as well (for better understanding).

1. Magic squares. An n x n matrix that is filled with the numbers 1, 2, 3, …, n² is a magic square if the sum of the elements in each row, in each column, and in the two diagonals is the same value.

Write a program that reads in 16 values from the keyboard, displays them in a 4 x 4 array, and tests whether they form a magic square.

Example:

              16     3       2      13

               5      10     11     8

               9       6       7      12

               4       15    14     1

You need to test two features:

1. Does each of the numbers 1, 2, …., 16 occur in the user input?
2. When the numbers are put into a square, are the sums of the rows, columns, and diagonals equal to each other?

Hint: use a two-dimentional array.

2. Implement a class Robot that simulates a robot wandering on an infinite plane. The robot is located at a point with integer coordinates and faces north, east, south, or west. Supply methods:

public void turnLeft()

public void turnRight()

public void move()

public Point getLocation()

public String getDirection()

The turnLeft and turnRight methods change the direction but not the location. The move method moves the robot by one unit in the direction it is facing. The getDirection method returns a string "N", "E", "S", or "W".

• Student data will be stored in a struct called studentType which has 4 members:
  • fName
  • lName
  • score
  • letterGrade
• Assume there are 20 students
• Your main() function will only have variable definitions and function calls
  • You MUST have the following functions
    • readData
    • assignGrade
    • findHighest
    • printHighest

1. Write Python program that use a while loop to determine how long it takes for an investment to double at a given interest rate.

The input will be an annualized interest rate, and the output is the number of years it takes an investment to double.

Note: The amount of initial investment can be any positive value, you can use $1.

Write pseudocode algorithms for the programs described as follows:- Available Credits A program that calculates a customer’s available credit should as the user for the following:  The customers maximum amount of credit  The amount of credit used by the customer Once these items have been entered, the program should calculate and display the customer’s available credit. You can calculate available credit by subtracting the amount of the credit used from the maximum amount of credit. (I need this in JAVA format please)
