#define STR1      "s"
#define STR2      "1"
#define STR3      STR1 ## STR2

#define图书馆深处有一个宏，我想快速知道它的确切值。有没有办法将定义的值存储到字符串中以便我可以打印它？

#define intgr 12
#define bnry 0b00000001
#define hex 0x0A
#define str "Hello World"

String myStr;

myStr = intgr;
cout<< myStr << endl;  //Simple enough, work no problem
//12              <- actual
//12              <- expected

myStr = bnry; // using "bnry" would not work as #define does not touch inside quotes
cout<< myStr << endl;
//1               <- actual
//0b00000001      <- expected

myStr = hex;
cout<< myStr << endl;
//10               <- actual
//0x0A             <- expected

myStr = str;
cout<< myStr << …
