关键字const，是英文单词constant的简写，它定义的是只读变量（read-only），而#define定义的是常量（constant ）。区别3：调试 #define定义的符号常量，因为是由预处理器（preprocessor）在编译前进行处理，所以在调试时不可见，无法在程序运行时调试符号常量。又因为没有明确的类型信息，导致程序出现BUG时，在源码中很...
you want a constant, not a const-qualified variable. The two are not remotely the same in the C language. For example, variables are not valid as part of initializers for static-storage-duration objects, as non-vla array dimensions (for example the size of an array in a structure, or ...
