A language-to-C (or C++) translator

[Stefano Simonucci]

Hi!
        I am trying to make a translator from a language (infix notation
        calculator, for example) to C (or C++). 
        For example I wish to traslate the following expression
        
        
        c=a*(b+c)+q 
        
        which originate from this sostitution rules
        
        NT-> c = NT              (NT = Non Terminal)
                 | 
              NT + q
               |
             a * NT
                  |
                (b+c)
        
        
        into the following 
        
        TMP_1=b+c;
        TMP_2=a*TMP_1;
        TMP_3=TMP_2+q;
        c=TMP_3;
        
        Do you know some example which treats a similar case?
        Thank you
            Stefano
