Write a program that allows the user to navigate through the lines of text in any text file. The program prompts the user for a filename and copies the lines of text from the file into a list. The program then prints the number of lines in the file and prompts the user for a line number. Actual line numbers range from 1 to the number of lines in the file. If the input is 0, the program quits. Otherwise, the program prints the text in that line number.

Input validation: You must print a friendly error message and allow the user to try again if the program cannot open the requested file, and whenever the user enters an invalid line number.

Here is a sample run (user input was changed to red for improved readability):

Enter the input file name: quotes.xtxt I cannot open the file quotes.xtxt - Please check the name and try again. Enter the input file name: quotes.txt The file has 16 lines. Enter a line number [0 to quit]: 1 1 : Hakuna Matata! Enter a line number [0 to quit]: -1 Try again. Line number must be between 0 and 16 Enter a line number [0 to quit]: 16 16 : Just keep swimming! Enter a line number [0 to quit]: 17 Try again. Line number must be between 0 and 16 Enter a line number [0 to quit]: 5 5 : It's kind of fun to do the impossible. Enter a line number [0 to quit]: A Try again. Please enter a number between 0 and 16 Enter a line number [0 to quit]: $ Try again. Please enter a number between 0 and 16 Enter a line number [0 to quit]: 4 4 : To infinity and beyond! Enter a line number [0 to quit]: 0
