我要回家想一想~

The stringify() macro can be used to turn any text in your code into a string, but only the exact text between the parentheses. There are no variable dereferencing or macro substitutions or any other sort of thing done.


/////////////////////////////////////////////////
#define stringify( name ) # name 

 enum enMyErrorValue
 {
 ERROR_INVALIDINPUT = 0,
 ERROR_NULLINPUT,
 ERROR_INPUTTOOMUCH,
 ERROR_IAMBUSY
 };

 const char * enMyErrorValueNames[] = 
 {
 stringify( ERROR_INVALIDINPUT ),
 stringify( ERROR_NULLINPUT ),
 stringify( ERROR_INPUTTOOMUCH ),
 stringify( ERROR_IAMBUSY )
 };

 void vPrintError( enMyErrorValue enError )
 {
 cout << enMyErrorValueNames[ enError ] << endl;
 }

 int main()
 {
 vPrintError((enMyErrorValue)1);
 }
