c++ - Invoking overload constructor within constructor -

i wondering either possible in c++ run constructor overload within constructor. know possible using regular methods. tryng do:

class foo { public:      foo();      foo(int val); };   foo::foo() {      foo(1); }  foo:foo(int val) {      std::cout << val; } 

this doesnt compile me. trying create 2 constructors 1 witch takes parameter , 1 sets default (the void one). aprichiate help.

class foo { public:      foo();      foo(int val); };   foo::foo() : foo(1) { }  foo:foo(int val) {      std::cout << val; }
