c++ - One method for doing the same with different variables -

i have that

class foo {     bar a, b, c;      void dostuffwitha();     void dostuffwithb();     void dostuffwithc(); } 

instead of writing implementation each of methods want template. how that?

cheers, dirk

edit:

i explicitly need know variable stuff (recursion):

class foo {     bar a, b, c;     foo* parent;      static void dorecursivestuffwitha(foo *_node) {         if(_node->parent==null) {              return;         } else {             dorecursivestuffwitha(_node->parent)         }      }     static void dorecursivestuffwithb(foo *_node) {         if(_node->parent==null) {             return;         } else {             dorecursivestuffwithb(_node->parent)         }      }     static void dorecursivestuffwithc(foo *_node) {         if(_node->parent==null) {             return;         } else {             dorecursivestuffwithc(_node->parent)         }      }  } 

edit2:

maybe explain better problem is:

class foo { public:     int a, b, c;  }  class bar { public:     void dostuffwithaoffoo(foo *_foo);     void dostuffwithboffoo(foo *_foo);     void dostuffwithcoffoo(foo *_foo);  } 

i want keep code simple , not have implement dostuffwithx 3 times...

i think want parameters...

class foo {     bar a, b, c;      void dostuffwithbar(bar x); } 

templates dealing variety of data-types , function arguments dealing variety of variables.
