- Here are the two programs which you may choose from to do this program: 1. Using Files - Student Line Up Modify the Student Line Up program described in Programming Challenge 14 which states: "A teacher has asked all of her students to line up according to their first name. For example, in one class Amy will at the front of the line, and Yolanda will be at the end. Write a program that prompts the user to enter the number of students in the class, then loops to read that many names. Once all of the names have been read, it reports which student would be at the front of the line and which one would be at the end of the line. You may assume that no two students have the same name. You are now to do this program reading names from a file. Names should be read in until there is no more data to be read. I am providing for you a file named LineUp.txt for you to use in writing this program. I suggest that you write it first without the file and then modify to add the file.arrow_forward(Check password) Some websites impose certain rules for passwords. Write a method that checks whether a string is a valid password. Suppose the password rules are as follows: A password must have at least eight characters. A password consists of only letters and digits. A password must contain at least two digits. Write a program that prompts the user to enter a password and displays Valid Password if the rules are followed or Invalid Password otherwise.arrow_forwardLanguage: Pyhon. Processing: Mode 3.54 (Jonathan Feinberg) Please post sketch fle code. Create a sketch named boston pass. This program will tell the user whether they passed a course or not Please read the entire question before starting. Create the following variables using an appropriate name and datatype (do not name them first variable, etc.) First variable: keeps track of the student mark (whole number) Second variable: keeps track of a Boolean value indicating if the student passed Third variable: keeps track of amount the student passed or failed by (whole number) Create the following functions using appropriate names (do not name them first function, etc.) First function: accepts one numeric value, purpose is to see if a student passed the course (50 or more), returns a true or false value. Second function: accepts one numeric value, purpose is to see how much more or less than 50 the student received, returns the amount higher or lower than 50. Third function: accepts one…arrow_forward
- Python Problem Description: Kevin is a freelance video producer who makes TV commercials for local businesses. When he makes a commercial, he usually films several short videos. Later, he puts these short videos together to make the final commercial. He has asked you to write the following two programs. A program that allows him to enter the running time (in seconds) of each short video in a project. The running times are saved to a file. A successful test run for this program would be as shown below: A program that reads the contents of the file, displays the running times, and then displays the total running time of all the segments. A successful test run for this program would be as shown below:arrow_forward4. The following program loads and displays an image. Complete the modify function to change the brightness of the image. The parameter m is a multiplication factor. modify will will multiply each pixel by m - that means you need to multiply the red, green, and blue channels by m, create a new pixel with new red, green, and blue values, and replace the old pixel with the new pixel. Be sure none of the red, green, and blue values exceed 255 (if a value is greater than 255, set it to 255). Your program should work for images of any size. A good example is the sepia tone exercise. Do not change the main function, except to try different values for the multiplication factor. Save & Run Load History 1 import image 3 def modify(pic, m): '''Multiply each pixel by m to darken or brighten an image''' pass #You can leave this or remove it #Your code here to change the brightness of the image 4 7 8 def main(): 9. '''Controls the program'" fname…arrow_forwardComplete the following incomplete program (begin by copy-pasting that into a new program file). The completed program will provide a user interface to draw as many circles as the user wants only by clicking in the window. After getting the number of circles (n) to draw as input from the user through the provided interface, the program should iterate n times. In each iteration it should wait for the user to click twice and draw a circle with center at the point where the user clicked first and with radius calculated as its distance from the second point where the user clicked. It should then fill the circle with a random color. Hints: Distance between two points with coordinates x1 & y1 and x2 & y2 and can be calculated as sqrt((x1-x2)2 + (y1-y2)2 ). To generate a random color, use randint(0,255) from the random libray to generate a random number between 0 and 255 (both inclusive). Use it three times to get the r, g and b values to generate a random color from graphics import…arrow_forward
- int a; System.out. println ("a = " + a); display Oa-0 The statement is valid and the displayed value of a is random. The statement is invalid because a is used without being initialized.arrow_forward(C Language) A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output. Assume also the maximum number of characters of all file names is 100.arrow_forwardObject-Oriented Programming (Using Java Language) - 6arrow_forward
