C# Preprocessor Directives

Preprocessor directives affect aspects of the compilation process. Preprocessor directives can be used to prevent the compiler from compiling code a particular piece of code. Preprocessor commands never actually get translated to any commands in the executable code.

1) Select preprocessor command used to declare and remove a symbol.
2) What is the compiled out put of following code?

#define PROFESSIONAL
#define W2K

#if ENTERPRISE
 Console.WriteLine("Windows Server Enterprize Edition");
 #if W2K
  Console.WriteLine("Windows 2000");
 #endif
#elif PROFESSIONAL
 #if W2K
  Console.WriteLine("Windows 2000");
 #else
  Console.WriteLine("C# Professional 2.0");
 #endif
#else
 Console.WriteLine("Dot Net Frame Work");
#endif
3) What is the compiled output of following code?

#define CSHARPQUESTION
#if CSHARPQUESTION && (ENTERPRISESERVER==false)
Console.WriteLine("SAMPLE C# QUESTIONS");
#else
Console.WriteLine("C# EXAMS");
#endif
4) Match the Preprocessor Directives(in Column) with their Description and Use(in Rows).
