    Struct and class

    Is it conventional to use both structs and classes in c++?i recall abachler saying he used struct for objects without member functions,i like this idea as providing clarity while working, to distinguish a complex data type from an object that 'does' things but is this valid c++?

    Yes, it is often a convention to use both, but for slightly different purposes. As for valid C++: duh. You can write object oriented C++ and have fun with class templates without ever using the class keyword.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    I think it is but some disagree with me. My personal policy is this:

    1. A struct cannot have methods, but may have a constructor in order to initialize data. A struct should not encapsulate any functionality.
    2. A class must encapsulate some type of functionality. If a class merely wraps access to variables - IE: is only composed of accessors and mutators - then it should most likely be a struct.
