    /// Implement an object hierarchy which contains at least classes for a rectangle, a trangle and a circle. 

    /// Implement a function float SumArea() that will iterate over an n-sized container of these shapes and sum their area

    /// Also implement functions void AddTriangle(float b, float h), void AddSquare(float size), void AddCircle(float radius).

    /// Note 1: You need only write a single function for each class (plus the constructor). 

    /// Note 2: The total sum of areas is required, regardless if the shapes overlap.

    /// Note 3: Try to make the iteration code as optimal as possible
