What is the difference between preprocessor variables and constants?
An example of an AI chatbot conversation about preprocessor variables and constants.
What is the difference between preprocessor variables and constants?
Preprocessor variables can change during compilation, while constants remain fixed. Would you like more details?
Can you give me an example of each?
Sure! A preprocessor variable might be defined with #define VAR 10, while a constant could be const int CONST_VAR = 20;.
When should I use a variable instead of a constant?
Use variables when you need to change values during compilation, and constants when you want to ensure values remain unchanged.
