Write a program that allows the user to navigate the lines of text in a file. The program should prompt the user for a filename and input the lines of text into a list. The program then enters a loop in which it 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 line associated with that number. An example file and the program input and output is shown below: example.txt Line 1. Line 2. Line 3. Enter the input file name: example.txt The file has 3 lines. Enter a line number [0 to quit]: 2 2 : Line 2. The file has 3 lines. Enter a line number [0 to quit]: 4 ERROR: line number must be less than 3. The file has 3 lines. Enter a line number [0 to quit]: 0 Make sure the program gracefully handles a user entering a line number that is too high. The program works as expected for given input, test 1 This test checks that the program gracefully handles a user entering a line number that exist in the text file and prints that line. Make sure your program gracefully handles a user entering a line number that exist in the file and prints that line. Test Case: Verify program with test file 1 Input: .test.txt 3 1 0 Results: The file has 5 lines The slings and arrows of outrageous fortune, To be, or not to be: that is the question: The program works as expected for given input, test 2 This test checks that the program gracefully handles a user entering a line number greater than the total line numbers in the text file. Make sure your program gracefully handles a user entering a number that is too high. Test case: Input: Verify program with test file 2 Input: .test.txt 3 1 0 Results: The file has 1 lines Battle of Adrianople Emperor Constantine Licinius near Adrianople Thrace with a Visgothic

Write a
An example file and the program input and output is shown below:
example.txt
Line 1.
Line 2.
Line 3.
Enter the input file name: example.txt
The file has 3 lines.
Enter a line number [0 to quit]: 2
2 : Line 2.
The file has 3 lines.
Enter a line number [0 to quit]: 4
ERROR: line number must be less than 3.
The file has 3 lines.
Enter a line number [0 to quit]: 0
Make sure the program gracefully handles a user entering a line number that is too high.
The program works as expected for given input, test 1
This test checks that the program gracefully handles a user entering a line number that exist in the text file and prints that line. Make sure your program gracefully handles a user entering a line number that exist in the file and prints that line.
Verify program with test file 1
The program works as expected for given input, test 2
This test checks that the program gracefully handles a user entering a line number greater than the total line numbers in the text file. Make sure your program gracefully handles a user entering a number that is too high.
