  1. Assessment – C++ Jim Fawcett CSE687 – Object Oriented Design Spring 2003

  2. C++ - Strengths • Is very powerful • Can program at very low level or very high level of abstraction • Has direct access to memory • User defined objects are first class citizens • Supports structured design, object oriented design, and generic design • Has a flexible memory model – static, stack, and heap • Language emphasizes performance • You don’t pay for features you don’t use • Almost no runtime checking • Is platform agnostic • Language and standard library apply to all platfroms • Easy to isolate platform dependencies in small modules. • Has a governing standard

  3. C++ Strengths • C++ is widely used • There are a lot of resources available: • Stroustrup’s Site • Herb Sutter's Site • CodeProject • Chris Sell's Site • Boost C++ Library • C++ at Microsoft

  4. C++ - Weaknesses • C++ is a complex language • Context dependent • Has a lot of rules that are not enforced by the compiler • Use virtual destructors • Use initializers in constructors • Don’t return references to temporaries • Most rules have exceptions • Compiler will generate void ctor, but only if no other ctor defined • Compiler will always generate copy ctor • Safety is not automatic • No bounds checking • Direct access to memory • Can break the type system with casts • Thrown exceptions can leave program in undefined state.

  5. C++ - Weaknesses • Things not supported by the language • Threads and synchronization • Directory services • Graphical User Interfaces • Network programming • Internet programming • Database operations

  6. C# - Strengths

  7. Ok, That’s a joke! I like C# too.

  8. Resources To Help You • Class Texts • Reference in SciTech Library – Carnagie Hall, south east corner • Friday morning help sessions: • 9:00 – 12:00 in CST 2-120 • Teaching Assistants: • Office Hours • Help Sessions • One or two session covering Visual Studio IDE • MadLab, 010 Link, scheduled as needed

  9. End of Assessment
