However, if I create objects using the constructor that takes no arguments, I get an error. It is actually not a solution to your code, but I had the same error message when incorrectly accessing the method of a class instance pointed to by myPointerToClass , e.

Parenthesis is not required to instantiate a class object when you don't intend to use a parameterised constructor. Obviously, the problem is that "anything"::iterator doesn't have a member called num so I need to dereference it. Which doesn't work like this:. I was having a similar error, it seems that the compiler misunderstand the call to the constructor without arguments.

I made it work by removing the parenthesis from the variable declaration, in your code something like this:. Turns out the compiler was translating this to. If you want to declare a new substance with no parameter knowing that the object have default parameters don't write.

The equivalent error for clang is: error: member reference base type 'float' is not a structure or union. Turns out the compiler was confusing local variable name 'data' and my member variable data. MykolaGolubyev has already given wonderful explanation. I was looking for a solution to do somthing like this MyClass obj MyAnotherClass but the compiler was interpreting it as a function declaration. Using this we can do something like this.
