Question

18.Write a program to overload a function area() as follows: i) double area( double a, double b) :Calculates and returns area of an ellipse Area = πab ii) double area (double r) : Calculates and returns area of a circle. Area = π × r x r iii) double area (double a, double b, double h): Calculates and returns area of a trapezium. Area = ½(a+b) × h The main() method need not to be written.

Answer 1

answer:

class func

{

public double area(double a,double b)

{

ar=22/7*a*b;

return area;

}

public double area(double r)

{

a=22/7*r*r;

return a;

}

public double area( double a,double b,double h)

{

are=1/2*(a+b)*h;

return are;

}

after this u can write the main method and call the functions in it
