Float Product

Create a simple C# console application that multiplies two floating-point numbers and displays the result.

Solution

Following snippet of code is a basic calculator program that prompts the user to enter two numbers, multiplies them together, and displays the product formatted to three decimal places.

namespace FloatProduct
{
    internal class Program
    {
        static void Main(string[] args)
        {
            Console.Write("x = ");
            var str = Console.ReadLine();
            var x = Convert.ToSingle(str);

            Console.Write("y = ");
            str = Console.ReadLine();
            var y = Convert.ToSingle(str);

            var res = x * y;
            Console.WriteLine("x * y = {0:f3}", res);
        }
    }
}

Features

• Accepts two floating-point number inputs from the user
• Performs multiplication operation
• Displays the result formatted to 3 decimal places
• Simple and straightforward console interface

Usage

1. Run the application
2. When prompted, enter the first number (x) and press Enter
3. Enter the second number (y) and press Enter
4. The program will display the product in the format: x * y = [result]

Example

x = 5.5
y = 2.3
x * y = 12.650

Building and Running

Using Visual Studio

1. Open the project in Visual Studio
2. Press F5 or click "Start" to build and run

Using .NET CLI

dotnet run

Code Structure

The application consists of a single Program class with a Main method that:

1. Reads two string inputs from the console
2. Converts them to single-precision floating-point numbers using Convert.ToSingle()
3. Multiplies the numbers
4. Outputs the result with 3 decimal places using string formatting
