How to use C++ concept I have learned with Visual Studio... visually?

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

Are you going to use the native C++/VC++ or the managed C++/CLI?
For example this code

looks like the managed one

like the native one.

Why are you passing PI to the functions and then setting its value? Why is the value different in both functions? Why not define a global const for PI once? Anyhow, your values for PI are incorrect.

PI = 3.1415926536 (to 10 DP)

What do you mean by "visually"? I assume you've downloaded VS 2017 Community and now want to write a simple program that reads some input and writes some output?

Then it's probably easiest to create a Windows Console Application. Here are instructions,
