From: pandit on 20 Feb 2007 01:44 hai, this is my very 1st post here. i don't know anything expect some Lisp, one of my friends taught me Lisp. i need to learn OOA-D 1st. so the question now is: Can i learn OOA-D without learning Proecdural/Modular design 1st? will that not handicap me? ( i am interested in C++, OOD & Templates and i do not want to learn C 1st, which is procedural. one of my friends, advised me to learn OOD 1st & then C++ but he has no idea on whether to learn procedural or modular 1st as a solid-base of programming or OOD) thanks -- pandit

BTW, i have also discussed the same with someone on my email. if you want, i can send you the relevant email-communication.

It will not handicap you. In fact, it is a distinct advantage. The OO paradigm is fundamentally different than the traditional procedural approaches. One cannot mix & match the two. A major problem that procedural developers have when they convert to the OO paradigm is that they essentially need to forget everything they learned about procedural development. > ( i am interested in C++, OOD & Templates and i do not want to learn C > 1st, which is procedural. one of my friends, advised me to learn OOD > 1st & then C++ but he has no idea on whether to learn procedural or > modular 1st as a solid-base of programming or OOD) Your friend is correct. All of the OOPLs are 3GLs so they make substantial compromises with the hardware computational models for things like procedural block structuring, stack-based scope, and procedural message passing. (That is especially true for C++.) As a result it is very tempting to overlay procedural thinking on the OOPLs because syntactically they are procedural languages with added abstract constructs on top. In addition, the procedural approaches are much more intuitive for algorithmic processing on computers because they grew up in academia solving scientific problems. The OO paradigm works from the opposite end of the spectrum by abstracting customer problem spaces rather than hardware computational models. So it is not very intuitive if one has already learned procedural development. So get a good OOA/D book and learn the fundamentals of the OO paradigm first.

Lahman, doesn't that mean: "a programmer will learn more about programming from algorithms and procedural approach rather than from OOD" ? > So get a good OOA/D book and learn the fundamentals of the OO paradigm > first.
