Re: [Dev-C++] #define for text ???

[Per W. <pw...@ia...>]

Defines don't scan strings, but you can make the substitution first and
then convert to a string:

#define TOSTRING(s) #s
#define MAXSTRING 256
#define MAXSTRINGNAME TOSTRING(MAXSTRING) ".ini"

printf("Filename: %s",MAXSTRINGNAME);

or just

strcat(iniFile,TOSTRING(MAXSTRING) ".ini");

Note also that the ## operator may be used by preprocessor to concatenate
two arguments, as:

#define CONCAT(a,b) a ## b
