C programming language Topic : Input/Output Program : Product list (product.c) Definition : The program reads a series of items form a file and displays the data in columns. The program obtains the file name from the command line. Each line of the file will have the following form: item, mm-dd-yyyy, price For example, suppose that the file contains the following lines: 123, 12.00, 12/25/2006 124, 18.30, 1/10/2020 Expected output: Item Unit Purchase Price Date 123 $ 12.00 12/25/2006 124 $ 18.30 1/10/2020

C programming language Criteria graded: Declare file pointers Open file Read from file Write to file Close file Instructions: Write a segment of code that opens a file called “numbers.txt” for reading. This file is known to have 10 numbers in it. Read in each number and print a ‘*’ to the screen if the number is even. If the number is odd, do nothing. Conclude by closing this file.
C# Write, compile, and test a console application named FileComparison that compares two files. First, use a text editor such as Notepad to save your favorite movie quote. Next, copy the file contents, and paste them into a word-processing program such as Word. Then, write the file-comparison application that displays the sizes of the two files as well as the ratio of their sizes to each other. To discover a file's size, you can create a System.IO.FileInfo object using statements such as the following, where FILE_NAME is a string that contains the name of the file, and size has been declared as an integer: FileInfo fileInfo = new FileInfo(FILE_NAME) ;Size = fileInfo.Length;
Body Mass Index Write a program that reads names, weights, and heights from bmi.dat (provided with starter code; do not change the file name). Use the information to calculate and displays a person’s body mass index (BMI). The BMI is often used to determine whether a person with a sedentary lifestyle is overweight or underweight for his or her height. A person’s BMI is calculated with the following formula: BMI = weight × 703 / height2 where weight is measured in pounds and height is measured in inches. The file is in the format name weightInKG heightInCM You will read the name, weight and height for 4 people from the file, and you will need to convert the weights in the file to pounds (note that 1 kilogram = 2.2 pounds) and the heights to inches (2.54 cm = 1 inch). The program should display the person's name along with the calculated BMI and a message indicating whether the person has optimal weight, is underweight, or is overweight. Your output should look like A person’s weight…

Background Information This assignment tests your understanding of and ability to apply the programming concepts we have covered in the unit so far, including the usage of variables, input and output, data types, selection, iteration, functions and data structures. Above all else, it tests your ability to design and then implement a solution to a problem using these concepts. Assignment Overview You are required to design and implement a "Word Game" program in which the user must identify a randomly selected "password" from a list of 8 words. The 8 words are selected at random from the list of 100 words in the starter file (word_game.py) provided to you with this assignment brief. Please use the starter file as the basis of your assignment code. The user has 4 attempts in which to guess the password. Whenever they guess incorrectly, they are told how many of the letters are the same between the word they guessed and the password. For example, if the password is "COMEDY" and…
CMPSC 125: C++ Programming Programming Project Assignment Program Description: This assignment focuses on while loops and random numbers. Turn in a file named Lab4_yourFirstName.cpp. Your program allows the user to play a game in which the program thinks of a random integer and accepts guesses from the user until the user guesses the number correctly. After each incorrect guess, you will tell the user whether the correct answer is higher or lower. The below shows one sample execution of your program. Your output will differ depending on the random numbers chosen and user input typed, but the overall output structure should match that shown below: I am thinking of a number between 1 and 100 Your guess? 50 [Enter] It's lower Your guess? 25 [Enter] It's higher Your guess? 35 [Enter] It's lower Your guess? 30 [Enter] It's higher Your guess? 32 (Enter] It's lower Your guess? 31 [Enter] You got it right in 6 guesses! Do you want to play again? Y[Enter] I am thinking of a number between 1 and…
