Question

Create a class angle that includes three member variables: an int for degrees, a float for minutes, and a char for the direction letter (N, S, E, or W). This class can hold either a latitude variable or a longitude variable. Write one member function to obtain an angle value (in degrees and minutes) and a direction from the user, and a second to display the angle value in 179°59.9’ E format. Also write a three-argument constructor. Write a main() program that displays an angle initialized with the constructor, and then, within a loop, allows the user to input any angle value, and then displays the value. You can use the hex character constant ‘\xF8’, which usually prints a degree (°) symbol.

Answer 1

#include <iostream>
using namespace std;
class Angle{
    int degrees;
    float minutes;
    char direction;
    public:
        Angle(int deg, float min, char dir): degrees(deg), minutes(min), direction(dir){}
        void getpos(){
            cout<<"Input degrees: "; cin>>degrees;
            cout<<"Input minutes: "; cin>>minutes;
            do{
                cout<<"Input direction: "; cin>>direction;
            }while(!(direction == 'E' || direction == 'W' || direction == 'N' || direction == 'S'));
        }
        void display(){
            cout<<degrees<<"\u00B0"<<minutes<<"\' "<<direction<<endl;
        }
};
int main(){
    Angle angle(179, 59.9, 'E');
    angle.display();
    int choice;
    do{
        angle.getpos();
        angle.display();
        cout<<"\nDo you want to enter a different angle?\n1. Yes\n2. Quit\n";
        cin>>choice;
    }while(choice == 1);
    return 0;
