I am learning C++. It is going really well. It is making other stuff I have done in programming really make sense. I was interested in getting started programming with C++ visually. I want to make a program that runs on Windows. I did not know where to get started. There is not a lot of info on the topic. I found a helpful video on YouTube that showed how to get set up. It leaves me off with code like so:
Code:
#include "MyForm.h"

using namespace System;
using namespace System::Windows::Forms;

[STAThreadAttribute]
int main(array<String^>^ args) {
	Application::EnableVisualStyles();
	Application::SetCompatibleTextRenderingDefault(false);
	Lotto1::MyForm form;
	Application::Run(%form);
	return 0;
}
I do not know how to continue from here. How would I add some code that performs something like calculating with overloaded functions! If anybody has any examples I would greatly apreciate seeing them. I want to make a program that calculates values for a sphere or a cylinder with an overloaded function like so:
Code:
int main()
{
	double Pi = 3.14790;
	cout << "Enter a radius: ";
	double radius = 0;
	cin >> radius;
	
	cout << "The sphere = " << calcRound(Pi, radius) << endl;

	cout << "Do you want to calculate the a cylinder? (yes = y/no = n) ";
	char answer1 = 'n';
	cin >> answer1;

	if (answer1 == 'y')
	{
		cout << "Enter a height: ";
		int height = 0;
		cin >> height;
		
		calcRound(Pi, radius, height);
		cout << "The cylinder = " << calcRound(Pi, radius, height) << endl;
	}

	return 0;
}

double calcRound(double Pi, double radius)
{
	Pi = 3.1409316;
	double sphere = 4 * Pi * radius * radius * radius;
	return sphere;
}

double calcRound(double Pi, double radius, int height)
{
	Pi = 3.14317529;
	double cylinder = Pi * radius * radius * height;
	return cylinder;
}
in func.h:
Code:
in func.h:

#ifndef FUNC_H_
#define FUNC_H_

double calcRound(double Pi, double radius);
double calcRound(double Pi, double radius, int height);

#endif // FUNC_H_

Thanks for any help
