class BASIC_SHAPE (abstract)
class BASIC_SHAPE
{
public:
double GET_AREA(double _AREA) { AREA = _AREA; return AREA; }
virtual double CALC_AREA() = 0;
private:
double AREA =0;
};
Class CIRCLE
class CIRCLE:public BASIC_SHAPE
{
public:
CIRCLE() { RADIUS = 0; }
CIRCLE(double _RADIUS) { RADIUS = _RADIUS; }
virtual double CALC_AREA() {
double TEMP2 = 3.14 * pow(RADIUS, 2);
return GET_AREA(TEMP2);
}

};
Class TRIANGLE
class TRIANGLE: BASIC_SHAPE
{
public:
TRIANGLE() { BASE = 0; HEIGHT = 0; }
TRIANGLE(double _BASE , double _HEIGHT) : BASE{_BASE}, HEIGHT{_HEIGHT} {}
virtual double CALC_AREA() {
double TEMP = 1 / 2 * (BASE * HEIGHT);
return GET_AREA(TEMP);
}
private:
double BASE, HEIGHT;
MAIN
CIRCLE SHAPE2;
TRIANGLE SHAPE3;
void main()
{
double RAD;
std::cout << "Enter a Circle Radius : ";
std::cin >> RAD;
CIRCLE SHAPE2(RAD);
CIRCLE* LEAD1 = new CIRCLE(RAD);
std::cout << "The Area is : " << LEAD1->CALC_AREA();
double BASE , HEIGHT;
std::cout << "\n\nEnter a Triangle Base : ";
std::cin >> BASE;
std::cout << "\nEnter a Triangle Height : ";
std::cin >> HEIGHT;
TRIANGLE SHAPE3(BASE, HEIGHT);
std::cout << SHAPE3.CALC_AREA();
}
it keeps returning zero when I input the BASE & HEIGHT
I have tried using arrow operator and get it with pointers put nothing worked , I,ve tried use pointers and other methods to give me the answer or the SUM of area but nothing happens . constructors or abstract Class are suspected but IDK how ??
