Write a class Heading that can be used to store one of the principal compass dir

Question

Write a class Heading that can be used to store one of the principal compass directions, 'N', 'E', 'S', 'W'. It will have the following methods. Constructor-builds a Heading as one of 'N', 'E', 'S', 'W', defaults to 'N'. You do NOT need to do any data validation (i.e., don't need to check the inputs or raise exceptions.) getretrive the Heading as a string. _repr_ -see output. right - changes the heading by turning right but 90 degrees, i.e., 'N' right arrow 'E' right arrow 'S' right arrow 'W' right arrow 'N' left - changes the heading by turning left by 90, i.e., the reverse of the above Constructor using an argument, repr, get, right left. Constructor called without an argument.

Explanation / Answer

#include <iostream>
using namespace std;

class Heading
{
   private:
       char myHeading; //Private member to store head value

   public:
       // parameterized constructor
       Heading(char heading)
       {
           cout << "You are moving towards - " << heading << endl;
           myHeading = heading;
       }
       // Default constructor
       Heading()
       {
           cout << "You are moving towards - N" << endl;
           myHeading = 'N';
       }
       // method gets Heading value
       void getHeading( )
       {
           cout << "h.get() - '" << myHeading << "'" << endl;
       }
       // used for seeing output
       void showHeadingDirection( )
       {
           cout << "Currently Heading('" << myHeading << "')" << endl << endl;
       }
       // used for turning right by 90 degree
       void turnRight( )
       {
           switch(myHeading){
      
           case 'N' :
               myHeading = 'E'; break;
           case 'E' :
               myHeading = 'S'; break;
           case 'S' :
               myHeading = 'W'; break;
           case 'W' :
               myHeading = 'N'; break;
           }
          
       }
       // used for turning left by 90 degree
       void turnLeft( )
       {
           switch(myHeading){
           case 'N' :
               myHeading = 'W'; break;
           case 'E' :
               myHeading = 'N'; break;
           case 'S' :
               myHeading = 'E'; break;
           case 'W' :
               myHeading = 'S'; break;
           }
          
       }
};

// Main function for the program
int main( )
{
cout << " h = Heading('E')";
   Heading heading('E');
heading.showHeadingDirection();
   heading.getHeading();

   cout << "heading.turnRight()" << endl;
   heading.turnRight();
   heading.showHeadingDirection();

   cout << "heading.turnRight()" << endl;
   heading.turnRight();
   heading.showHeadingDirection();

   cout << "heading.turnRight()" << endl;
   heading.turnRight();
   heading.showHeadingDirection();

   cout << "heading.turnLeft()" << endl;
   heading.turnLeft();
   heading.showHeadingDirection();
  
   cout << " with out parameter in constrcor - " << endl;
   cout << "head = Heading()" << endl;
   Heading head;
   head.showHeadingDirection();

cout << "head.turnLeft()" << endl;
head.turnLeft();
   heading.showHeadingDirection();
  
   cout << "head.turnRight()" << endl;
   head.turnRight();
   head.showHeadingDirection();

   cout << "head.turnRight()" << endl;
   head.turnRight();
   head.showHeadingDirection();

   return 0;
}
