Let's start with the solution:

Step by Step solution about How to resolve the algorithm Command-line arguments step by step in the C# programming language

The two code snippets shown are written in C# and are used to print the command-line arguments passed to the program. The first snippet uses the args array, which is automatically populated by the runtime with the command-line arguments passed to the program. The second snippet uses the Environment.GetCommandLineArgs method to get the command-line arguments as an array of strings.

Both snippets iterate over the args array and print each argument to the console using the String.Format method. The String.Format method is used to format a string using a specified format string and arguments. In this case, the format string is "Argument {0} is '{1}'" and the arguments are the index of the argument and the argument itself.

The output of both snippets will be a list of the command-line arguments passed to the program, with each argument being printed on its own line. For example, if the program is called with the following command-line arguments:

myprogram.exe arg1 arg2 arg3

The output of the program will be:

Argument 0 is 'arg1'
Argument 1 is 'arg2'
Argument 2 is 'arg3'

Source code in the csharp programming language

using System;

namespace RosettaCode {
    class Program {
        static void Main(string[] args) {
            for (int i = 0; i < args.Length; i++)
                Console.WriteLine(String.Format("Argument {0} is '{1}'", i, args[i]));
        }
    }
}


using System;

namespace RosettaCode {
    class Program {
        static void Main() {
            string[] args = Environment.GetCommandLineArgs();
            for (int i = 0; i < args.Length; i++)
                Console.WriteLine(String.Format("Argument {0} is '{1}'", i, args[i]));
        }
    }
}
