Question

I have a class defined called extBlock.

I then make an instance of that class with this

extBlock mainBlock = new extBlock(1, 1024);

I get this error:
error C2440: ‘initializing’ : cannot convert from ‘extBlock *’ to ‘extBlock’

Can anyone help me with why I am getting this error.

I have seen examples online of declaring it like this with a pointer

extBlock *mainBlock = new extBlock(1, 1024);

But if I do it this way it does not let me call the functions of mainBlock

Answer 1

This isn’t C#: new extBlock returns a pointer to an extBlock, and you’re trying to assign that pointer to a value type (which would be an incompatible cast).

What you want to write here is

extBlock mainBlock(1, 1024);

And the reason you couldn’t call methods on the second code snippet was probably because you were using the . operator instead of the -> (arrow) operator needed to dereference a pointer.
