How are portions of a program disabled in demo versions?..

Answer / Balram

In C programming, portions of a program can be disabled in demo versions through various techniques. Some common methods include: (1) Compiler directives like #ifndef, #define, and #endif to conditional compile specific code sections based on preprocessor symbols, (2) Dynamic function loading and selectively not loading crucial functions for the demo version, and (3) Using conditional compilation flags provided by the build system to control whether certain features or functions are included in the final compiled binary.
