Example: classes and constructors
using namespace std;
class Line {
public:
void setLength( double len );
double getLength( void );
Line();
private:
double length;
};
Line::Line(void) {
cout << "Object is being created" << endl;
}
void Line::setLength( double len ) {
length = len;
}
double Line::getLength( void ) {
return length;
}
int main() {
Line line;
line.setLength(6.0);
cout << "Length of line : " << line.getLength() <<endl;
return 0;
}
