Challenge 1 question 3 makes no sense.

Question

It took me HOURS to find a diff. solution to call a function using arrow syntax in the final line of code.

myPtr -> foo();

Is the canned answer. It took me a while to figure out since Xcode. VS 2017. Dev c++. Not a single one accepted the line of code with error:
This declaration has no storage class or type specifier

Either the question is archaic as in older compilers may take the solution/the answer is incorrect. If the solution does work for you outside of the challenge please post the entire code.

Answer 1

That's not true. If you create an object via pointer the arrow operator is the way to call it's methods.
It works just like in the question.

I guess you do some things wrong. To be able to explain your error you should post what you tried.

Answer 2

Doh.... sololearn tends to write blocks of code and not the entire working program meaning the libraries and namespaces are usually left unwritten. That’s what I should have paid more attention to.
