Write a function (in a file called convert_knots.cpp) that converts knots into miles per minute. The function needs to take in an int (knot) as the argument and return a double value (miles per minute). Write a main function (at the bottom of convert_knots.cpp) that reads an integer from the terminal, and prints out the number converted to miles per minute (as a double floating point) by calling your function.

Write a function that reads a single line of numbers from a file named "question1.txt", and returns the average of the numbers read. For example, if the file is as follows: ----- question1.txt ----- 1 3 5 -2 4 0 6 -2 -3 ------------------------- then the function must return 12/9 = 1.33333 """ def file_average(): return # Remove this line to answer this question
Call the file: sinDrawline.cpp For this assignment, you will be creating two functions, alongside a main function: 1) toRadians: takes in degrees as input, and returns radians. Given a specified number of degrees, the radians is equal to degrees * PI/180. Important: Be sure to declare PI to be 3.14159. This is so that mimir always comes up with the same answers no matter which server is used. 2) Drawline: takes in two parameters: a character and numRepetitions and prints the character numRepetitions times, followed by a newline. In your main function, for every 5 degrees between 0 and 360, calculate and print out the value of sin(toRadians(degree)) like so: GIVEN 45 DEGREES: sin(45) = 0.70711 To use the sin function, make sure to include cmath in your program. Be sure to set decimal precision to 5 places! Every 90 degrees (including 0 and 360), print out a line of 30 dashes ('-') using drawline after your print out the value of sin. Inside main() For values between 0 and 360, in 5…
Write a program that receives a coded message file(Lab3ExtraCreditCT.txt) from your local espionage agent and decodes it into a file using standard English. The problem is your agent forgot to tell you the key used to decode the message. Fortunately, this is a simple substitution code consistently using 1 alphanumeric character to represent another, this is case sensitive. All other characters are not substituted, so a space will always be a space, a – will always be a –, a @ will always be a @, etcetera. You may use the following table to help you, it contains the most common letters used in the English language in descending order. E A R I O T N S L C U D P M H G B F Y W K V X Z J Q 0 5 3 2 4 6 8 1 9 7 Using the following key to convert plaintext to coded text: Plaintext = Now is the time for all good men to come to the aid of their country.

(5) Write a function called copy_even_lines() that takes two strings (filenames) as input parameters and copies every other line from the first file into the second. That is, counting from 0, it copies the 0th line, the 2nd line, the 4th line, etc. from the first file to the second file. You may assume that both files exist. (6) Write a python program that asks the user for two filenames and calls your function copy_even_lines() from (5) using those two filenames. If one or more files do not exist, your program must handle the exception by repeating the prompts until valid filenames are entered.
Write a program that reads words from a file (filename given as a string parameter) and prints the occurance of each word(case insensitive). And print the words in alphabetical order. For example, if the file contains text Love is free free is love then the function should print free:2 is:2 love:2 def count_word(filename): # YOUR CODE HERE raise NotImplementedError()
Write a function in python that takes an acrostic as the input and will return the secret message to the user. Include optional arguments to state what makes the first line, as well as what position should be used.a) SATOR\nAREPO\nTENET\nOPERA\nROTAS\n1. Use each index position 0 through 4 b)Elizabeth it is in vain you say\t“Love not” – thou sayest it in so sweet a way:\tIn vain those words from thee or L.E.L.\tZantippe’s talents had enforced so well:Ah!

write a program that computes and prints the average of the numbers in a text file. you should make use of two higher-order functions to simplify the design 1. Modify the data in numbers.txt 45.6 66.7 88.8 100.3 22.4 98.1 2. Run the average.py and numbers.txt to get the desired output. Enter the input file name: numbers.txt The average is 70.31666666666666 3. Please explain the algorithm in 3 sentences Please screenshot input ans output window
Write a complete C program that inputs marks of a student in 5 courses using any loop and writes these marks into an output file named txt. After that, it reads scores from myElements.txt and computes the grades based on the table below using a programmer-defined function char computeGrade(double score), and displays the grades on screen. Score Grade >= 90 A 80-89 B 70-79 C 60-69 D <= 59 F ----- please, write 1. the c program code 2. include comments on your code 3. contents of the file myElements.txt 4. sample output Thank you so much
Implement a function wordCount, which reads a text file, and returns thenumber of words in the file. You can assume the file only contains thealphabet characters and the space character. However there may be morethan one space character between two words, so “abc abc” and “abc abc”,for example, are both two words. int wordCount ( const char * filename ) {}
Write a function called max_age(inFile, outFile, breed) for a (python program), that takes three strings as input parameters. The function reads all the data from the inFile (1st input parameter) and writes data to the outFile (2nd input parameter) as described below. Each line in the input file represents a pet record and has the following format. name, breed, age where name and breed are strings, and age is an integer value. Your function must find the oldest pet of a given breed (3rd input parameter) from the inFile and write the following information to the outFile. breed, total records of this breed name of the oldest pet, age of the oldest pet Note that outFile must only have these two lines of information. Suppose, inFile contains the following data: shadow, longhair, 3 poshi, bangal, 5 mikus, longhair, 4 tigger, calico, 9 If you call this function with breed = "longhair", then the following must be written in the outFile: longhair, 2 mikus, 4 Your…
Write a program that reads a text and outputs the letters, together with their counts, as explainedbelow in the function printResults. Your program should not have any global variables. Allinformation should be accessed through the parameters of the functions. Your program shouldhave the at least the following functions:• Function main – calls all the functions• Function openFile – opens the input and ouput files. This program has the file streamdeclare a refence parameter. An appropriate error message should be displayed if the filedoes not exist. The program must ask the user for the names of the input and output files.• Function countLetters – counts every of uppercase letters A – Z and lower-case lettersfrom a – z in the text file opened in the function openFile. This information should be storedin an array of structures. Both the array and file identifiers must be passed as parameters.• Function printResults – prints the number of uppercase letters for every occurrence of A–Zand…
1. Write a function num_double to read file (f1.txt), double all the numbers, keep the string (no change), and write to another file (f2.txt), for example: >>># f1.txt-“I have 5 books and 3 pens...” >>> f2 = num_double(f1) >>> # f2.txt – “I have 10 books and 6 pens ...”
