Declare and initialize pointer to a class instance in one line

Question

Assuming I have a class MyClass(int i), I know I can do:

int j = 1;
MyClass instance(j);

i.e. declare and initialize instance in one line. Is there a short syntax that allows to do the same for a pointer to MyClass?

MyClass *instance = new MyClass(j);

works, but the syntax has "MyClass" two times, which is a bit redundant.

MyClass *instance = new MyClass(j);

How about:

 auto instance = new MyClass(j);

Oh, busted, didn't think of `auto`. Well it doesn't include `MyClass` twice but I think OP was looking something shorted. Anyway, you deserve an upvote. – gsamaras Jun 19 '16 at 00:34
