Invoking overload constructor within constructor

I was wondering either it is possible in C++ to run a constructor overload within another constructor. I know it is possible using regular methods. What I am trying to do:

class Foo
{
public:
     Foo();
     Foo(int val);
}; 

Foo::Foo()
{
     Foo(1);
}

Foo:Foo(int val)
{
     std::cout << val;
}

This doesn't compile for me. I am trying to create 2 constructors one which takes a parameter and one that sets it as default (the void one).

Solution 
  • class Foo
{
public:
     Foo();
     Foo(int val);
}; 

Foo::Foo() : Foo(1)
{
}

Foo:Foo(int val)
{
     std::cout << val;
}
