macro question

[abir]

Hi,
this is not related to strict c++ , but macro.
I want a statement to be generated like
std::size_t count = sizeof(trace2)/sizeof(coord_t) ;
for (std::size_t i = 0; i< count; i += 2){
std::cout<<trac e2[i]<<" "<<trace2[i+1]<<std::endl;
}

when i write LOAD_TOKEN(2)

so the main problem is to essentially catenate "token" with a token
id.
I am looking at ##, but in between something fails to compile.
thanks

Usually it works like this:

#define LOAD_TOKEN(n) ....token##n... .

where "..." has to be your code, of course.
