"Am I limiting my child’s future by choosing self-led learning?" "Am I trusting my own core self in the process of being a compassionate and curious parent-guide?" These are valid concerns for parents ...
Learning is any relatively permanent change in behaviour that occurs as a result of experience. Learning is the process of having one’s behaviour modified, more or less permanently, by what he does and the consequences of his action, or by what he observes.
How can I use #if inside #define in the C preprocessor? Ask Question Asked 15 years, 11 months ago Modified 1 year, 1 month ago
In other words, when the compiler starts building your code, no #define statements or anything like that is left. A good way to understand what the preprocessor does to your code is to get hold of the preprocessed output and look at it.
#define WIDTH 10 is a preprocessor directive that allows you to specify a name (WIDTH) and its replacement text (10). The preprocessor parses the source file and each occurrence of the name is replaced by its associated text.
The #define directive is a preprocessor directive; the preprocessor replaces those macros by their body before the compiler even sees it. Think of it as an automatic search and replace of your source code. A const variable declaration declares an actual variable in the language, which you can use... well, like a real variable: take its address, pass it around, use it, cast/convert it, etc. Oh ...
Is it better to use static const variables than #define preprocessor? Or does it maybe depend on the context? What are advantages/disadvantages for each method?
