How to get calculation eveluated at preprocessor

Hi everyone,

I got a following issue.




The output of the RESULT_STRING will be "Result is (3 * 10 * 10)" instead of

Anyone has any idea how to make the output to "Result is 300"??

Any help will be greatly appreciated.

ps. The value of M_NUM is generated during build time, so I cannot calculated
the value of ABC first and directly insert it into the string..

Thank you very much.

Cheers,
Angela

Preprocessor does not do math (well, it does, but only in #if =
directives). it is a text manipulation engine.

Unless you really do just need to add two zeros, the only solution to thisis

Unless you really do just need to add two zeros, the only solution to this
is to use sprintf.

CString sz;
sz.Format( "Result is %d", ABC );

Thanks Igor and Tim..hmm..

Thanks Igor and Tim..

hmm.. Actually I need

And the resulted string is used in a RC file to show the "Special build
description":

VALUE "SpecialBuild", RESULT_STRING

So I guess.. does it mean there is no way to do it??

Thank you very much.

Not with the preprocessor, no. I suppose the same build process that =
generated M_NUM could also be made to generate ABC.

hmm.. I do not have the source code of the build process which generatesM_NUM..

hmm.. maybe I write my own process to do the calculation and add the string
during build time..
or.. maybe I can live with the fact that just show the M_NUM on the file and
let people to do the calculation themselves.. haa...

Thank you for both Igor and Tim..

Have a nice day~~
