Answer 1

```
// Product.cs
// Calculating the product of three integers.
using System;

class Product
{
static void Main()
{
int x; // stores first number to be entered by user
int y; // stores second number to be entered by user
int z; // stores third number to be entered by user
int result; // product of numbers
Console.Write("Enter first integer: "); // prompt for input
x = int.Parse(Console.ReadLine()); // read first integer
Console.Write("Enter second integer: "); // prompt for input
y = int.Parse(Console.ReadLine()); // read second integer

Console.Write("Enter third integer: "); // prompt for input
z = int.Parse(Console.ReadLine()); // read third integer

result = x * y * z; // calculate the product of the numbers
Console.WriteLine($"Product is {result}");
} // end Main
} // end class Product
```

Enter first integer: 10
Enter second integer: 20
Enter third integer: 30
Product is 6000
