Question

Add the length parameter to your module, then change your loop so that it displays the numbers from 1 to length on the screen. Modify main to pass a literal number (e.g., 8) to draw a horizontal line. Run your program and verify that you now see numbers from 1 to the given length displayed on the screen.

Answer 1

To draw a horizontal line of a given length on the screen, you need to use a scale. Modify the program to add a length parameter and change the loop to display numbers from 1 to the given length. Run the modified program to verify the changes.

Step-by-step explanation:

To draw a horizontal line of a given length, you need to use a scale. The scale is a ratio that represents the relationship between the actual length and the length on the display. In this case, the unit scale is used, where 500 feet is represented by 5 inches. So, for a line 8 inches long on the display, the actual length would be 800 feet.

To modify the program, you need to add a length parameter to the module and change the loop to display numbers from 1 to the given length. For example, if you pass 8 as the length, the program should display numbers 1 to 8 on the screen.

By running the modified program and verifying that it displays the numbers from 1 to the given length, you can confirm that the changes have been successfully implemented.
