Calling template function within template class

Question

Disclaimer: The following question probably is so easy that I might be shocked seeing the first answer. Furthermore, I want to apologize for any duplicate questions - syntac

Answer 1

obj.bar<double>(1,2); // This line is faulty.

The template keyword is required here, as obj is an instance of a type Foo<T> which depends on the template parameter T, and so the above should be written as:

obj.template bar<double>(1,2); //This line is corrected :-)

Read @Johannes's answer here for detail explanation:

• Where and why do I have to put the "template" and "typename" keywords?

Answer 2

As so often: Once the question was posted, the answer came all by itself. Correcting the faulty line to

return obj.template bar<double>(1,2);

yields the expected results.

Thanks for reading...

Answer 3

Could this be a case of foo.template bar‹ double >?
