Theinformation of the booking services has several information such as slot number and status thatare stored in a file named “Services.txt”. In this case, the slot number will be used to locate theslot, while the status will be used to know the availability of the slot (i.e. ’1’ indicate the slotis occupied and ’0’ indicate the slot is available). Assuming there are 12 slot available, andhave been indexed from 1 to 12. You are required to develop a C program that can access thedata from “Services.txt”. file, and manage the slot information with the following requirements:Based on user selection, the program will perform one of the two following options:1 – Search. The program should be able to display the status, based on the slot numberentered by user.2 – Booking. A function (in 3 (a)) is called to list out all available slot (which isindicated by status ’0’). Another function (in 3 (b)) will be called to…createDatabaseOfProfiles(String filename) This method creates and populates the database array with the profiles from the input file (profile.txt) filename parameter. Each profile includes a persons' name and two DNA sequences. 1. Reads the number of profiles from the input file AND create the database array to hold that number profiles. 2. Reads the profiles from the input file. 3. For each person in the file 1. creates a Profile object with the information from file (see input file format below). 2. insert the newly created profile into the next position in the database array (instance variable).
- In the student sample program files for this chapter, you will find a text file namedGasPrices.txt. The file contains the weekly average prices for a gallon of gas in the UnitedStates, beginning on April 5th, 1993, and ending on August 26th, 2013. Figure 8-7 shows anexample of the first few lines of the file’s contents:Figure 8-7 The GasPrices.txt fileDescriptionEach line in the file contains the average price for a gallon of gas on a specific date. Each line isformatted in the following way:MM-DD-YYYY:PriceMM is the two-digit month, DD is the two-digit day, and YYYY is the four-digit year. Price is theaverage price per gallon of gas on the specified date.For this assignment, you are to write one or more programs that read the contents of the file andperform the following calculations:Average Price Per Year: Calculate the average price of gas per year, for each year in thefile.

Notice that, unlike the program in this chapter, this program lets the user perform more than one calculation, it stores the values the user enters in a text file, and it displays the total miles, total gallons, and average miles per gallon when the program starts and after each entry. Add a function that calculates the miles per gallon Define a function named calculate_mpg() before the main() function that calculates the miles per gallon. This function should accept two double values for the miles and gallons, round the result to two decimal places, and return the result as a double type. Modify the code in the main() function so it uses the calculate_mpg() function. Note that the miles per gallon is calculated in three different places. Move the definition for the calculate_mpg() function after the main() function. When you run…
- Your goal is to implement an application that reads a file, modify its content, and writes the modification back to the same file. The file includes 2 lines of integers. The first line indicates which integer on the second line has been selected (active). And the second line lists all the integers in the list (maximum of 10). Your application should have a menu that is constantly displayed on the screen (see the menu below). Right below the menu, the program should display list of all integers in the file (second line). Also, it should show which integer is currently selected (active) by displaying an arrow to its left. The user should be able to select a menu item by entering its associated key and pressing the Enter key on the keyboard. “Select Down” selects the next item in the list. If the item at the end of the list is selected, this option selects the first item in the list. “Select Up” selects the previous item in the list. If the first item is selected, this option selects the…______________is NOT a super global array. a. $_GET b. $_REQUEST c. $_ERRORS d. $_SESSION1. Create a file that contains 20 integers or download the attached file twenty-integers.txttwenty-integers.txt reads:12 20 13 45 67 90 100 34 56 89 33 44 66 77 88 99 20 69 45 20 Create a program that: 2. Declares a c-style string array that will store a filename. 3. Prompts the user to enter a filename. Store the file name declared in the c-string. 4. Opens the file. Write code to check the file state. If the file fails to open, display a message and exit the program. 5. Declare an array that holds 20 integers. Read the 20 integers from the file into the array. 6. Write a function that accepts the filled array as a parameter and determines the MAXIMUM value in the array. Return the maximum value from the function (the function will be of type int). 7. Print ALL the array values AND print the maximum value in the array using a range-based for loop. Use informational messages. Ensure the output is readable.
- Fill-in-the-Blank A(n)__________ container uses keys to rapidly access elements.Java Programing Joyce Farrell 13-8 Create an application named StudentsStanding.java that allows you to enter student data that consists of an ID number, first name, last name, and grade point average. Have the program accept input until ZZZ is entered for the ID number. Depending on whether the student’s grade point average is at least 2.0, output each record either to a file of students in good standing (StudentsGoodStanding.txt) or those on academic probation (StudentsAcademicProbation.txt). Create an application named StudentsStanding2.java that displays each record in the two files created in the StudentsStanding application. Display a heading to introduce the list produced from each file. For each record, display the ID number, first name, last name, grade point average, and the amount by which the grade point average exceeds or falls short of the 2.0 cutoff. For example, the output should be formatted as follows (note that the student info may vary): Probationary Standing…You are given a file which has an Australian state name and a university name in each line.

You may assume that each state is one word long. Furthermore, make sure to only record the names of unique states - so do not record any state twice. HINT: use the in keyword. E.g. ▸ Run 1 ls = [1, 2 if 4 in ls: 3 4 elif 4 not in ls: 2, 3] print("4 is in list") 5 print("4 is NOT in list") PYTHON You MUST use open(), read(), split(), sort(),…
