How to fix this error no matching function for call?

#include <iostream>

#include <cstdlib>
using namespace std;

error: no matching function for call to 'Shape3D::Shape3D(double&, double&, double&)'

This is because your Shape3D class doesn't have a constructor that takes three doubles.

erro : no matching function for call to 'RightRectangularPyramid::RightRectangularPyramid()'

Since you defined RightRectangularPyramid(double width, double length, double height) constructor in your code, compiler won't generate code for default constructor RightRectangularPyramid().

error: no matching function for call to 'Sphere::Sphere()'

Same reason as above.

While compiler error message is straightforward you probably need to either provide definition of those functions or update your code (most likely) so that your code won't automatically call those functions. To fix your code following changes are necessary:

  1. Remove call to Shape3D(double&,double&,double&) from the class RightRectangularPyramid's constructor.
  2. Construct Sphere and RightRectangularPyramid with appropriate arguments.
  3. Make the functions in Shape3D pure virtual.

Here

RightRectangularPyramid(double width, double length, double height) : Shape3D(width, length, height) {

for some reason you are trying to pass the width length and height to a Shape3D constructor which doesn't exist. Just remove the constructor call

RightRectangularPyramid(double width, double length, double height) {

Here

RightRectangularPyramid rectangle;

you are trying to create a pyramid with no width, length and height, but you wrote the RightRectangularPyramid constructor that needs a width, length and height. You need to add these values, e.g.

RightRectangularPyramid rectangle(1.0, 2.0, 3.0);

Here, same problem

Sphere sphere;

you are trying to create a sphere with no radius, but you wrote the Sphere constructor that needs a radius. So you need to supply one, e.g.

Sphere sphere(99.9);

Sometimes compiler error messages are cryptic, but these seem rather obvious, the compiler told you exactly what was wrong.
