The Chat-A-While phone company provides service to six area codes and charges the per-minute rates for phone calls shown in Figure 6-25 (below).
Write a program named ChatAWhile that stores the area codes and rates in parallel arrays and allows a user to enter an area code and the length of time for a call in minutes, and then display the total cost of the call.
For example if the area code is in the array, such as 715, and the call length is 22 minutes, the output should be:
Your phone call to area 715 costs $0.16 per minute For 22 minutes the total is $3.52
If the area code is not in the array, such as 111, the program should not accept a call length, and instead output Sorry - no calls allowed to area 111.

In order to prepend the $ to currency values, the program will need to use the CultureInfo.GetCultureInfo method. In order to do this,…
JAVA I cannot figure this one out no matter what I do I cannot get it to run. Please write it in a student way not in an too advance way.
Write an application containing three parallel arrays that hold 10 elements each. The first array hold four-digit student ID numbers, the second array holds first names, and the third array holds the students’ grade point averages. Use dialog boxes to accept a student ID number and display the student’s first name and grade point average. If a match is not found, display an error message that includes the invalid ID number and allow the user to search for a new ID number.
Suppose a teacher has five students who have taken
four tests. The teacher uses the following grading
scales to assign a letter grade to a student, based on
the average of his or her four test scores.
Test Score Letter Grade
90-100
80-89

Create an application that uses an array of strings to
hold the five student names, an array of five strings to
hold each student's letter grades, and five arrays of
four single precision numbers to hold each student's
set of test scores.

- For each of the following exercises, you may choose to write a console-based or GUI application, or both. Write a program named CheckZips that is used by a package delivery service to check delivery areas. The program contains an array that holds the 10 zip codes of areas to which the company makes deliveries. Prompt a user to enter a zip code, and display a message indicating whether the zip code is in the companys delivery area.arrow_forwardin C#, Visual Basic Write an app for Boston Airlines that allows a customer to reserve a seat on the airline’s only plane (capacity: 10 seats). Radio buttons should allow the choice between First Class and Economy. The app should then assign a seat in the first-class section (seats 1–5) or the economy section (seats 6–10). Use a one-dimensional array of type bool to represent the seating chart of the plane. Initialize all the elements of the array to false to indicate that all the seats are empty. As each seat is assigned, set the corresponding element of the array to true to indicate that the seat is no longer available. Your app should never assign a seat that has already been assigned. When the economy section is full, your app should ask the person if it is acceptable to be placed in the first-class section (and vice versa). If yes, make the appropriate seat assignment. If no, display the message “Next flight leaves in 3 hours."arrow_forwardWrite a program called DeliveryCharges for the package delivery service in Exercise 4.

- Using C# in Microsoft Visual Studio Create an application that simulates a game of tic-tac-toe. The application should use a two-dimensional int array to simulate the game board in memory. When the user clicks the New Game button, the application should step through the array, storing a random number in the range of 0 through 1 in each element.The number 0 represents the letter O, and the number 1 represents the letterX. The form should then be updated to display the game board. The application should display a message indicating whether player X won, player Y won, or the game was a tie.arrow_forwardThe rainfalls in Manama are available for each day of the past four weeks.

- Write a Java application and use a two-dimensional array that will store the five top artist sales for 2017. The application must also hold the artist sales for CDs, DVDs and BLU RAY items.Your program must: Q.1.1 Create a two-dimensional array to contain the three sale items for five different artists. A single array must be used to store the artist names. Q.1.2 Allow a user to enter in a number, ranging from 1 to 5, which will represent the artist position with regards to the album sales.Q.1.3 Printout the artist name including the CD, DVD, BLU RAY sales amounts and total sales.arrow_forwardJAVA Your teacher has created two arrays, each holding the results of tests, say Test 1 and Test 2. You need to create a new array which holds the averages of these two tests. You may assume that the first element of the first test array refers to the student who also has the grade in the first element of the second test, and the last element in each array are the grades the last student earned for each test. All students received grades for both tests, meaning both test arrays are of the same length. Complete the method, named makeAverage, in the class named Grades.java. There are two parameters to this method: the first is the integer array representing the grades of the first test, and the second is the array containing the grades of the second test. The new average array should be returned by the method. The grades should be treated as double variables. For example, consider the test grades for the five students in the following arrays: [ 87 ] [ 91 ] [ 76 ] [ 76 ] [ 94 ]…arrow_forwardWrite a C# console application named MaxMin that asks the user to enter 5 integers, representing the test scores of 5 students. For each input score, you need to check and make sure it is valid (i.e., in between 0 and 100). Store the 5 integers in an int array, and then find and display the highest and the lowest scores on the screen. For example, if you have the 5 scores as {85, 72, 65, 98, 80}, then the output message should be "The highest score is 98, and the lowest score is 65". Hint: use a while loop.arrow_forward
