- Average Number of WordsIf you have downloaded the source code from the Computer Science Portal you will find a filenamed text.txt in the Chapter 08 folder. The text that is in the file is stored as one sentenceper line. Write a program that reads the file’s contents and calculates the average number ofwords per sentence.(You can access the Computer Science Portal at www.pearsonhighered.com/gaddis.)arrow_forwardC 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.arrow_forwardBody 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…arrow_forward
- 6. Average Number of WordsIf you have downloaded the source code from the Premium Companion Website you willfind a file named text.txt in the Chapter 08 folder. The text that is in the file is storedas one sentence per line. Write a program that reads the file’s contents and calculates theaverage number of words per sentence.arrow_forward*Code in Python A file concordance tracks the unique words in a file and their frequencies. Write a program that displays a concordance for a file. The program should output the unique words and their frequencies in alphabetical order. Variations are to track sequences of two words and their frequencies, or n words and their frequencies. Below is an example file along with the program input and output: example.txt I AM SAM I AM SAM SAM I AM Enter the input file name: example.txt AM 3 I 3 SAM 3 The program should handle input files of varying length (lines).arrow_forwardC++ Add a search command that asks the user for a string and finds the first line that contains that string. The search starts at the first line currently displayed and stops at the end of the file. If the string is found, the line that contains it is displayed at the top. In case the user enters a string X that does not occur in the file, the program should print the error message: ERROR: string "X" was not found.arrow_forward
- C lanaguge Managing Student Information! C LANGUAGE We're going to build a student information management system. The user should be shown a menu with four options: display student initials, display student GPAs, add students, or exit the program. If the user chooses to exit, the program should end. Otherwise, if the user chooses to display the student initials, the contents of the students.txt file should be read, and just the student number and initials should be displayed to the user in a tabular format. If the user chooses to display the student GPAs, the contents of the students.txt file should be read, and just the student number and GPAs should be displayed to the user in a tabular format. If the user chooses to add students, they should be prompted for the number of studnets they’d like to add. They should then be prompted that many times for a studnet number, a GPA, a first initial, and a last initial. Each of the new items should be saved to the students.txt file.…arrow_forwardLine Numbers Write a program that asks the user for the name of a file. The program should display the contents of the file with each line preceded with a line number followed by a colon. The line numbering should start at 1. Pythonarrow_forwardGirlNames.txt This file contains a list of the 200 most popular names given to girls born in the United States from the year 2000 through 2009. BoyNames.txt This file contains a list of the 200 most popular names given to boys born in the United States from the year 2000 through 2009. Write a program that reads the contents of the two files into two separate lists. The user should be able to enter a boy’s name, a girl’s name, or both, and the application will display messages indicating whether the names were among the most popular. **programming language is python** ** must use a def main(): function** *please include some comments* i aslo have the .txt files but no wya to upload themarrow_forward
- C-Programming Write a program that tells you how many words in a text file are unique (meaning the word only appears once in the text file). List of words in text file:…arrow_forwardC++ Create a program that reads a file containing a list of songs and prints the songs to the screen one at a time. After each song is printed, except for the last song, the program asks the user to press enter for more. After the last song, the program should say that this was the last song and quit. If there were no songs in the file to begin with, the program should say that there are no songs to show and quit. The program should begin by asking the user for the name of the input file. Each song consists of a title, artist, and year. In the file, each song is given on three consecutive lines. Create this program using a class Song.arrow_forwardData File: Example #1AAAAABBBBBCCCCCDDDDDAAEBCBAFBBCDCECDADDEFEEFFFExample #2AAATAABTBBBBCCCCTCDDTDDDAASAABBSBBCCSCCDSDDDEEEAEEFBFFFDDF Write a program that will give the user a brief introduction, then allow the user to type in the name of the file to be analyzed, the name of the data file to generate, and then process the data to match the output that is shown below. This DNA test measures the various parts of the sequence and assigns them a letter. While the letters could be anything from A to Z, the only letters that matter for this test are the letters {A,B,C,D} all other letters can be ignored completely. A sample will be tested, given a length of time and then tested again. Each time the scientist will generate a line of data. Here is one Example: Example #1 AAAAABBBBBCCCCCDDDDD AAEBCBAFBBCDCECDADDEFEEFFF At first glance the sample looks significantly different after the second test. But if you look at the data, you will note that since we only care about A,B,C,D’s that the…arrow_forward
