[Dev-C++] What are the differences between a struct and a class?

[Andre M. B. <and...@su...>]

Dear users,

   When we need to develop a OO app, one way is to create
classes, with attributes and methods. After this we instanciate
the class in our program, as it is, or with some specialization.

   Thinking only about ANSI-C, we can create structs with the
usual fields (attributes), but we can associate functions inside
the struct too. After this operation, putting this struct definition
in a .h file, we can make a variable declaration defining it as
a struct type (the one created in the .h file).

   In this scenario, disconsidering the protected/public/private
features, please talk to me abou what a OO app can
do that a struct like .c program can´t.

Regards
Andre
