Question

An angle may be measured in degrees and minutes.

Eg: ∠a=70 degrees 35 mins, ∠b=50 degrees 40 mins
sum of angles c is ∠c=∠a + ∠b = 121 degrees 15 mins (Since 1 degree = 60 mins)

Create a class called 'angle' with the following details
instance variables
int deg, int min - to store degrees and minutes of an angle
methods
void enterangles() -to input an angle
angle sumangle(angle a,angle b) -to find sum of the angles and display it.
void display() - to display the degrees and minutes of an angle

WAP in BlueJ using the above class to accept 2 angles and find their sum and display it.

Answer 1

In c++ :-

#include<iostream.h>

#include<conio.h>

class angle

{

int deg;

int min;

public:

angle();

angle(int,int);

void enterangles();

angle sumangle(angle,angle);

void display ();

};

angle()

{

deg=0;

min=0;

}

angle(int d,int m)

{

deg=d;

min=m;

}

void angle:: enterangles ()

{

cout<<"enter degree:";

cin>>deg;

cout<<"enter min";

cin>>min;

}

angle angle:: sumangle(angle a,angle b)

{

int deg;

int min;

deg=a.deg+b.deg;

min=a.min+b.min;

if(min>60)

{

min- = 60;

}

deg++;

return angle (deg,min);

}

void angle::display()

{

cout<<"degree="<<deg;

cout<<"minute="<<min;

}

void main()

{

clrscr();

angle a,b,sum;

a.enterangles();

b.enterangles();

sum.sumangle(a,b);

sum.display();

getch();

}

Feeling good, to help you guys !!
