How are macros in C different from pre-defined data types in terms of storage? -

how values associated , b? how values of , b assigned variables (when of different data types)

#include <stdio.h>  #define 1 #define b 1  int main(void) {       printf("%s", (a & b) ? "t":"f");     return 0;  } 

they not stored, replaced when appear in code preprocessor. code "literally" equivalent to

printf("%s", (1 & 1) ? "t" : "f");
