What is the difference between a preprocessor and a compiler?
An example of an AI chatbot conversation about preprocessors and compilers in programming.
Can you explain the difference between a preprocessor and a compiler?
Sure! A preprocessor prepares the code for compilation by handling directives, while a compiler translates the code into machine language.
What kind of directives does a preprocessor handle?
The preprocessor handles directives like #include, #define, and conditional compilation directives.
Does the preprocessor run before the compiler?
Yes, the preprocessor runs first, processing the code before it is passed to the compiler for translation.
Can you give an example of how a preprocessor directive works?
Certainly! For example, #define can be used to create constants. If you define #define PI 3.14, every occurrence of PI in the code will be replaced with 3.14 before compilation.
