Write a program that asks the user for the name of a file. The program should display the contents of the file on the screen. Each line of screen output should be preceded with a line number, followed by a colon. The line numbering should start at 1. Here is an example:
George Rolland
127 Academy Street
Brasstown, NC 28706
If the file's contents won't fit on a single screen, the program should display 24 lines of output at a time, and then pause. Each time the program pauses, it should wait for the user to strike a key before the next 24 lines are displayed.
Note: Save text below as the file to use and name it forChap12.txt file for this assignment. The line numbers should NOT be reset for each screen.

- C++HurdleWords The HurdleWords class is mostly provided to you. HurdleWords is constructed from two files in the data/ folder: ● valid_guesses.txt (all 5 letter guesses considered to be valid words to guess), and ● valid_hurdles.txt (all words that may be selected to be the secret Hurdle.) ● Note: you may edit both text files if you’d like to add custom words to your game. HurdleWords stores all potential valid Hurdles from valid_hurdles.txt into a vector of strings (valid_hurdles_), and all valid guesses from valid_guesses.txt into an unordered set of strings (valid_guesses_). A set is simply a data structure that contains no duplicates and allows for a speedy lookup to check if a given element exists within the set. Because there are over 10,000 valid guesses, we store them in an unordered set to leverage their speediness, as you will need to check if a user-submitted guess is considered valid (i.e. their guess is considered a valid guess in the dictionary). You are responsible for…arrow_forwardC++Inventory Program Write a program that uses a structure to store the following inventory data in a file: Item Description Quantity on Hand Wholesale Cost Retail Cost Date Added to Inventory The program should have a menu that allows the user to perform the following tasks: • Add new records to the file. • Display any record in the file. • Change any record in the file. Input Validation: The program should not accept quantities, or wholesale or retail costs, less than 0.The program should not accept dates that the programmer determines are unreasonable.arrow_forwardPythonarrow_forward

A food truck has multiple food items as well as a menu which contains a selection of the food items which will be sold for that day. A maximum of 10 food items can appear on the menu for any day. For each food item keep a code, description, category, price and quantity in stock (code, description and category are not usually changed). Create a comma delimited text file called "items.txt" for 15 or more food items, indicating the item's description, category, price and quantity in stock.

- 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!

Problem description The rocket is traveling through space. Each asteroid has (x, y, z) position in space, where x, y, and z are the distances in kilometers from the rocket which is at 0,0,0. It will read a file asteroids.txt that represents the ID and location of each asteroid. The distance between the rocket and each asteroid is calculated based on the asteroid’s X, Y, Z position using the following formula. √(x2+y2+z2) This program must be secure. The user puts their name and password, if both match the list you have in a text file on the disk (ID.txt), then the user gets access to the program. The program should allow 3 tries for name and password entry, if unsuccessful after 3 tries the program should print a message and terminate.
