Question

Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and events (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.

Answer 1

Answer:

The C code for the problem is given below

Explanation:

#include <stdio.h>

int main() {

   int highwayNumber;

   int primaryNumber;

   scanf("%d", &highwayNumber);

   if (highwayNumber >= 1 && highwayNumber <= 999) {

       if (highwayNumber <= 99) {

           if (highwayNumber % 2 == 0) {

               printf("I-%d is primary, going east/west.\n", highwayNumber);

           } else {

               printf("I-%d is primary, going north/south.\n", highwayNumber);

           }

       } else {

           primaryNumber = highwayNumber;

           highwayNumber %= 100;

           if (highwayNumber % 2 == 0) {

               printf("I-%d is auxiliary, serving the I-%d, going east/west.\n", primaryNumber, highwayNumber);

           } else {

               printf("I-%d is auxiliary, serving the I-%d, going north/south.\n", primaryNumber, highwayNumber);

           }

       }

   } else {

       printf("%d is not a valid interstate highway number.\n", highwayNumber);

   }

   return 0;

}

Answer 2

Answer:

CODE IN C++:

#include <iostream>

using namespace std;

int main()

{

int inputNumber ;

cout << "Enter an interstate highway number:";

cin >> inputNumber ;

if(inputNumber<=0 || inputNumber >= 1000)

cout << inputNumber << " is not a valid interstate highway number" << endl ;

else{

if(inputNumber > 99){

cout << "I-"<<inputNumber<< " is auxiliary, ";

int temp = inputNumber % 100 ;

cout <<"serving I-"<<temp<<", ";

if(temp%2==0){

cout << "going east/west." << endl;

}

else{

cout << "going north/south." << endl;

}

}

else{

cout << "I-"<<inputNumber<< " is primary, ";

if(inputNumber%2==0){

cout << "going east/west." << endl;

}

else{

cout << "going north/south." << endl;

}

}

}

return 0;

}
