Step by Step solution about How to resolve the algorithm String interpolation (included) step by step in the C# programming language

Program Class:

• Defines the Program class which is the entry point of the program.

Main Method:

• Defines the main method, which is the starting point of the program.
• The method is static, meaning it belongs to the Program class and not to specific instances of the class.

String Interpolation:

• Uses string interpolation to dynamically set the value of the formatted variable.
• String interpolation allows you to embed expressions within string literals using the $ prefix.
• In this case, the expression $"Mary had a {extra} lamb." evaluates to the string "Mary had a little lamb."
• It is equivalent to the following code:

string formatted = string.Format("Mary had a {0} lamb.", extra);

Console Output:

• Writes the value of the formatted variable to the console.

class Program
{
    static void Main()
    {
        string extra = "little";
        string formatted = $"Mary had a {extra} lamb.";
        System.Console.WriteLine(formatted);
    }
}
