We will compile an example program to calculate the area of different geometric shapes. The code has a main function in a file called compute-areas.cpp:
#include "geometry_circle.hpp"#include "geometry_polygon.hpp"#include "geometry_rhombus.hpp"#include "geometry_square.hpp"#include <cstdlib>#include <iostream>int main() { using namespace geometry; double radius = 2.5293; double A_circle = area::circle(radius); std::cout << "A circle of radius " << radius << " has an area of " << A_circle << std::endl; int nSides = 19; double side = 1.29312; double A_polygon = area::polygon(nSides, side); std::cout << "A regular polygon of " << nSides << " sides of length " << side << " has an area of " << A_polygon << std::endl; double d1 = ...
