I tried to run a simple preprocessor code on my code-block 13.12 IDE. But it shows an error
Code: 
error: request for member 'b' in something not a structure or union|

Here is the piece of code:

Code: 
#define CUBE(x) (x.x.x)

main()
{
    int  a,  b=3 ;
    a =  CUBE(b++);
    printf (  "\n%d  %d",  a,  b  )  ;
}

Even I am not using any structure and union in my code...

Any help?
 

Simple solution. As b isn't a structure, don't apply structure syntax (x.x.x) to it...

What do you want to achieve with "x.x.x" ?

Nothing much as I want to just brush up my preprocessor fundamentals, saw that piece of code and I was expecting some output rather than an "ERROR".

What would be the solution then? I think that this type of error I never got when executed on TURBO C compiler.

I guess you want to define cube function with #define macro so 

Code C - [expand]

#define CUBE(int x)   x*x*x


as answered earlier you are using .(dot) for multiplication insted of *(star)
