] | Declaring potentially ambiguous functions in C++ does not produce any ambiguity errors. Ambiguity takes place when you attempt to *refer* to these functions in an ambiguous way. In your example ambiguity will occur if you try to default-construct your object.
Strictly speaking, it is perfectly normal to have declarati... | Ambiguity doesn't arise because the private constructor is not even considered when you write `A a(1)`, as you pass an argument to it, and the private constructor doesn't take any argument.
However, if you write `A a`, then there will be ambiguity, because both constructors are candidates, and the compiler cannot deci... |
