ode in Python   Write a program that inputs a text file. The program should print the unique words in the file in alphabetical order. Uppercase words should take precedence over lowercase words. For example, 'Z' comes before 'a'. The input file can contain one or more sentences, or be a multiline list of words. An example input file is shown below: example.txt the quick brown fox jumps over the lazy dog An example of the program's output is shown below: Enter the input file name: example.txt brown dog

1. string   color  =  "Yellow";      //What does this code do?   a. declares a structure   b. calls a function   c. creates a character array   d. creates an object   2. The strcmp function returns ____________________.   a. 0 if the two strings are equal   b. a negative value if the first argument is alphabetically less than the second   c. a positive value if the first argument is alphabetically greater than the second   d. all of a through c are true

Strings and string manipulation Part A: Building upon an Existing Solution  Redesign the solution in the following manner. Ask the user for their name and their email addresses before you display the results of the conversions. When the user enters their email address search the string for the @ symbol. If the symbol is not found, ask the user to re-enter their email address till they get it right. When you display the conversion output to the user, you must include the user’s name in the output. Part B: Write Something New! Write a complete and syntactically correct Python program to solve the following problem: Input a date in numeric format from the user e.g. mm/dd/yy. Examine the month entered by the user, if it is larger than 12 or smaller than 1, issue an error message and ask for input again. Perform similar validation tests for the date and year. Year must be 2015. (Any other year is invalid).  In addition, the year must only be two digits long.. Once all input has been…

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.…

5. Charge Account Validation If you have downloaded the source code from the Computer Science Portal you will find a file named charge_accounts.txt in the Chapter 07 folder. This file has a list of a com- pany's valid charge account numbers. Each account number is a seven-digit number, such as 5658845. Programming Exercises 403 program Write a program that reads the contents of the file into a list. The program should then ask the user to enter a charge account number. The program should determine whether the number is valid by searching for it in the list. If the number is in the list, the should display a message indicating the number is valid. If the number is not in the list, the program should display a message indicating the number is invalid. (You can access the

Java Task Write a for loop that prints the characters stored in a String object backward. The String is entered by the user.  ***Use ch = phrase.charAt(i); to get the character that is in index i of the String phrase.**** For example The user enters “Good morning!” The printout should be “!gninrom dooG”.

profile-image Time remaining: 00 : 09 : 42 Computer Science C++. Need help writing a program that plays the game of Hangman. The program should pick a word (which is either coded directly into the program or read from a text file) and display the following:   Guess the word: XXXXXX   Each X represents a letter. The user tries to guess the letters in the word. The appropriate response yes or no should be displayed after each guess. After each incorrect guess, display the diagram with another body part filled. After seven incorrect guesses, the user should be hanged. The display should look as follows:   O   /|\   |   / \   After each guess, display all user guesses. If the user guesses the word correctly, display: " Congratulations!!! You guessed my word. Play again? yes/no "   Please help in making this code and if possible to include steps to learn what most of the lines and functions do in order to understand it better. Thank you.

Java please   Line is a String object that holds an unknown number of int values separated by spaces.  Write a segment of code that computes and displays the sum of the values in line.

Task 3. Remove white spaces and special symbols Program asks user to input a string to remove white spaces and special symbols (dashes, commas and dots). User inputs a string (with several words) and program prints out the input string without white spaces and special symbols. You may use Scan objects and loops. Example: Input a string to remove special symbols: hey, - i like may. Result: heyilikemay
