Preprocessor Reference

Visual C++

This reference explains the preprocessor as it is implemented in Microsoft C/C++. The preprocessor performs preliminary operations on C and C++ files before they are passed to the compiler. The preprocessor allows you to:
  • Define and undefine macros.
  • Expand macros.
  • Conditionally compile code.
  • Insert specified files.
  • Specify compile-time error messages.
  • Apply machine-specific rules to specified sections of code.
