Explanation / Answer

1) using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace hello_world
{
public partial class FormMain : Form
{
private int count = 0;

public FormMain()
{
InitializeComponent();
}

private void ButtonHello_Click(object sender, EventArgs e)
{
count++;   
LabelCount.Text = count.ToString();
LabelHello.Text = "Hello, world!";   
}
}

2) #include <iostream>
using namespace std;

const int NUM_SCORES = 3;

int main()
{
int score1, score2, score3;
float ave;
cout << "Enter 3 scores separated by spaces: ";
cin >> score1 >> score2 >> score3;

ave = float(score1 + score2 + score3) / float(NUM_SCORES);

cout << "The average of " << score1 << ", " << score2 << ", and "
<< score3 << " is " << ave << "." << endl;
return 0;
