Adding and Deleting

rsalzman94 (13)
i am writing a program to list the 8 planets, then you select which planet you want. it gives you the mass of the planet, the radius, then you use the mass and radius of the planet to find the surface area(sphere formula) and the density of the planet. along with those options, you have to add and delete a planet from the list and then sort them alphabetically. All i am having trouble with is the adding and deleting part.
the code the adding and deleting from the list would go in cases 9 and 10.

heres my code as of this point.

I suggest looking into std::list to store your planets data. Then you can do something like this:

1
2
3
4
5
6
7
8
9
10
11
12
13
14

16

#include <iostream>
#include <string>
#include <list>

class Planet
{
public:
	Planet(const std::string& name) : mName(name) {}
	bool operator==(const Planet& planet)
	{
		return planet.Name() == mName;
	}

	std::string Name() const
	{
		return mName;
	}

private:
	std::string mName;
};

int main ()
{
	std::list<Planet> planets;

	// Add Earth and Mars
	planets.push_back(Planet("Earth"));
	planets.push_back(Planet("Mars"));

	// Delete earth
	planets.remove(Planet("Earth"));

	// Print all planets
	for (std::list<Planet>::iterator it = planets.begin(); it != planets.end(); ++it)
	{
		std::cout << it->Name() << '\n';
	}

	while (true) {}
	return 0;
}


P.S: Your mercury is spelt wrong.

The ony reason why I'm formatting the code the way I did is because I had an assignment that was similar to this but instead of the planets I had to use shapes to find surface area and some other formulas. I'll give that code a shot. I appreciate the help guys. Thanks
