In C# If we do not pass string[] args array of string inside the Main() function which is the entry point of the application then what effect will be happen on application?

As far as you are not going to pass command line arguments, no need to write string[] args.

no change on entry point and it's starts normally with Main method.

No Effect. 1) The parameter of the Main method is a String array that represents the command-line arguments. 2) Command line arguments commonly get used when you need to pass information to your application at runtime. 3) For example if you were writing a program that copies a file from one location to another you would probably pass the two locations as command line arguments. For example: 4) Copy.exe C:\file1.txt C:\file2.txt

No Effects

No, Effects on entry of point of your application if you are creating the EXE like MyDemoApp.exe class Program { static void Main(string[] args) { foreach (var arg in args) { Console.WriteLine(arg); } } } Command line like this: MyDemoApp.exe agrument1 agrument2 agrument3 if you are not passing the string[] agrs then you can not paas the arguments in command line. but Exe will run fine.
