How to resolve the algorithm Compile-time calculation step by step in the Visual Basic .NET programming language

Table of Contents

Problem Statement

Some programming languages allow calculation of values at compile time.

Calculate   10!   (ten factorial)   at compile time. Print the result when the program is run. Discuss what limitations apply to compile-time calculations in your language.

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Compile-time calculation step by step in the Visual Basic .NET programming language

Source code in the visual programming language

Module Program
    Const FACTORIAL_10 = 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1

    Sub Main()
        Console.WriteLine(FACTORIAL_10)
    End Sub
End Module


.class private auto ansi sealed Program
	extends [System.Runtime]System.Object
{
	.custom instance void Microsoft.VisualBasic.CompilerServices.StandardModuleAttribute::.ctor() = (
		01 00 00 00
	)
	// Fields
	.field private static literal int32 FACTORIAL_10 = int32(3628800)

	// Methods
	.method public static 
		void Main () cil managed 
	{
		.custom instance void [System.Runtime]System.STAThreadAttribute::.ctor() = (
			01 00 00 00
		)
		// Method begins at RVA 0x2060
		// Code size 11 (0xb)
		.maxstack 8
		.entrypoint

		IL_0000: ldc.i4 3628800
		IL_0005: call void [System.Console]System.Console::WriteLine(int32)
		IL_000a: ret
	} // end of method Program::Main

} // end of class Program


Module Program
    Sub Main()
        Console.WriteLine(10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1)
    End Sub
End Module


Module Program
    Sub Main()
        Dim factorial As Integer
        factorial = 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1
        Console.WriteLine(factorial)
    End Sub
End Module
