What is #define size in C?
#define has no size as it’s not a type but a plain text substitution into your C++ code. #define is a preprocessing directive and it runs before your code even begins to be compiled . So 4 bytes on x86 and x64 probably, but this is compiler dependent.
What is the size of float in C?

What do you need to know about the C preprocessor?
In simple terms, a C Preprocessor is just a text substitution tool and it instructs the compiler to do required pre-processing before the actual compilation. We’ll refer to the C Preprocessor as CPP.
