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, I-405 services I-5, and I-290 services I-90.
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 between 1 and 999, the output is:
0 is not a valid interstate highway number.
This is the code I am using, but something is not functioning properly.
import java.util.Scanner;
public class LabProgram{
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int highwayNumber;
int primaryNumber=0;
highwayNumber = scnr.nextInt();
if (highwayNumber >= 1 && highwayNumber <=>
if (highwayNumber <= 99)="">
if (highwayNumber % 2 == 0)
System.out.println("I-" + highwayNumber + " is primary, going east/west.");
else
System.out.println("I-" + highwayNumber + " is primary, going north/south.");
}
else
{
primaryNumber = highwayNumber;
highwayNumber %= 100;
System.out.println(primaryNumber + " is an auxiliary highway, serving primary highway " + highwayNumber);
}
else
{
System.out.println(primaryNumber + " is not a valid interstate highway number.");
}
}
}
