difference between () and = when declaring variables


simple question.. im well educated in java but not in c++. im reading about pointers right now and in examples i see, for example:
Code:
int myval(5);
int anotherVar = 3;
they do the same thing right? using (x) is just another way of doing =x, i assume?

thanks for the input.

They are equivalents in this case... but you have to be careful.

The blah var() syntax actually calls the constructor for the class blah. In the case of the primitives that will always work, in the case of non-primitives you can only do that if they have a constructor defined with the parameters you are passing in.
