Can I call a constructor from another constructor (do constructor chaining) in C++?

Question

As a C# developer I\'m used to running through constructors:

class Test {
    public Test() {
        DoSomething();

I believe you can call a constructor from a constructor. It will compile and run. I recently saw someone do this and it ran on both Windows and Linux.

It just doesn't do what you want. The inner constructor will construct a temporary local object which gets deleted once the outer constructor returns. They would have to be different constructors as well or you would create a recursive call.
