The object model of C++ is almost entirely from Simula rather than from smalltalk. The object model of Simula is less dynamic and the language itself is based on Algol rather than being built from scratch like Smalltalk. In many ways, Simulas rather than Smalltalks object model has been the most influential, through C++ and later Java and C#.
