4.21 LAB 4 Program 1: Interstate highway numbers
Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go
east/west. Auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. Thus, 1-405
services 1-5, and 1-290 services 1-90. Note: 200 is not a valid auxiliary highway because 00 is not a valid primary highway number.
Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also
indicate if the (primary) highway runs north/south or east/west.
Ex: If the input is:
90
the output is:
I-90 is primary, going east/west.
Ex: If the input is:
290
the output is:
I-290 is auxiliary, serving I-90, going east/west.
Ex: If the input is:
0
or any number not beween 1 and 999, the output is:
0 is not a valid interstate highway number.
Ex: If the input is:
200
the output is:
200 is not a valid interstate highway number.

Expert Solution

Step 1

PROGRAM STRUCTURE:

Take the highway number from the user.
Use the if condition for checking the highway number is between 1 and 99 or not.
If the condition gets satisfied then check whether the highway number is even or not.
If the highway number is even then print east/west and if the highway number is odd then print north/south.
Then use else if condition whether the highway number is between 100 and 999 or not.
