Question

Find cube of a variable by using a class cube and calling it by pointer argument?

Answer 1

How far did you get and in what language?

Answer 2

For Java the class could be constructed as follows, you can reference the class in your mainline code and use a pointer to call it and return the value. Hope this helps.

public class Cube {
private double depth; // Cube's depth
private Square square;

// no-argument constructor
public Cube()
{
square = new Square( 0, 0, 0 );
depth = 0;
}

// constructor with arguments
public Cube( int xValue, int yValue, double sideValue )
{
square = new Square( xValue, yValue, sideValue );
setDepth( sideValue );
}

// set Cube's depth
public void setDepth( double depthValue )
{
depth = ( depthValue < 0.0 ? 0.0 : depthValue );
}

// get Cube's depth
public double getDepth()
{
return depth;
}

// set x
public void setX( int x )
{
square.setX( x );
}

// return x
public int getX()
{
return square.getX();
}

// set y
public void setY( int y )
{
square.setY( y );
}

// return y
public int getY()
{
return square.getY();
}

// set side length
public void setSideLength( double lengthValue )
{
square.setSideLength( lengthValue );
}

// return side length
public double getSideLength()
{
return square.getSideLength();
}
// calculate Cube area
public double getArea()
{
return 6 * square.getArea();
}

// calculate Cube volume
public double getVolume()
{
return square.getArea() * getDepth();
}

// return String representation of Cube object
public String toString()
{
return square.toString() + "; Depth = " + getDepth();
}

} // end class Cube
