9. Game Evolution C++ and Java What was the benefit of C++ and Java:  Merge functions and data into a class  Object orientation helps modeling graphic interfaces, complex systems, and objects in games.  Java went a step further and added garbage collection.

10. Game Evolution C++ and Java What was poor about C++ and Java:  Modeled complex relationships between objects poorly.  C++ was not binary platform independent.  Java failed to have high performance.

12. Game Evolution Next Generation What is parametric polymorphism? Allows you to use high-level algorithms and containers (arrays, trees, sorting routines) in a very general way. C++ attempts this concept poorly with templates.

13. Game Evolution Next Generation To simplify this concept lets look at the following task: // add arrays A, B. Put result in C. int A[10], B[10], C[10]; A solution is: int i; for (i=0;i<=9;i++) C[i] = A[i] + B[i];

14. Game Evolution Next Generation Beginners (newbies) would think that because they can add integers as C=A+B, and the arrays seem compatible that they should be able to type: C=A+B;

15. Game Evolution Next Generation Any C programmer would know that this syntax is incorrect, but try explaining it to a newbie. Whenever you can replace a complex piece of code with an equivalent simpler piece of code, you’ve multiplied your productivity as a programmer. This is the basic idea of polymorphism.
