Share some codes which you want to convert.
Ill be able to help you in a better way then...
For normal defines of constants, you may simply use constants of the type you wish to store.
Eg -
#define PI 3.14159 == const double PI = 3.14159;
And for functions:
#define sqr(x) x*x
==
inline double sqr(double x)
{ return x*x; }
Here, inline indicates that the function is to be copied before evaluation, like a macro. But, using inline is safer and convenient...

Sorry, I wasn't able to understand what you wanted to do.
Try this:

You can run "gcc -E mycode.cpp" to do nothing put expand preprocessor definitions, if you are using gcc.

useful suggestion.
but i just wana expand my macro rather than rewrite them.
more macros,less codes,very very cool.
inline add codes,i dont like it.
