simple inheritance question

I have a base class foo:

Code:

---

class foo {
    public:
          foo(char *val);
};

---

from which I want to derive bar. For now, bar can be identical to foo:

Code:

---

class bar : public foo {
};

---

However, when I use the constructor I get told:

error: no matching function for call to ‘bar::bar(char*&)’
note: candidates are: bar::bar()
note: bar::bar(const donor&)

How do I set this up so I can use the constructor for foo as defined:

Code:

---

foo::foo (char *ptr) {

---

Constructors can't be inherited. You'd need to define a constructor for bar, and invoke foo's constructor:

Code:

---

class bar : public foo {
public:
    bar(char* val): foo(val) {}
};

---

Thanks!
