Destructors will never have any arguments.
#include <iostream>
class Line
{
public:
void setLength( double len );
double getLength( void );
Line(); // This is the constructor declaration
~Line(); // This is the destructor: declaration
private:
double length;
};
// Member functions definitions including constructor
Line::Line(void)
{
cout << "Object is being created" << endl;
}
Line::~Line(void)
{
cout << "Object is being deleted" << endl;
}
void Line::setLength( double len )
{
length = len;
}
double Line::getLength( void )
{
return length;
}
// Main function for the program
void main( )
{
Line line;
// set line length
line.setLength(6.0);
cout << "Length of line : " << line.getLength() <<endl;
getch();
}
Output:
Object is being created
Length of line : 6
Object is being deleted
