Preprocessor brain drain

[Christopher Benson-Manica]

If I have a symbol defined at preprocessing (assume it's all digits),
how can I make that symbol into a string constant for compiling?

begin followup to Christopher Benson-Manica:

int main()
{
#define MAGIC 31337
#define QUOTE_SYM(s) #s
#define QUOTE_NUM(s) QUOTE_SYM(s)
puts(QUOTE_SYM(MAGIC));
puts(QUOTE_NUM(MAGIC));
return 0;
}

how can I make that symbol into a string constant for compiling?

#define STRINGIZE(x) STRINGIZE_HELPER(x)
#define STRINGIZE_HELPER(x) #x

#define SYMBOL all digits
puts (STRINGIZE(SYMBOL));
