I mean Cobol is one of the language has wide use

mikesmith(老猫)
COBOL's dominance in underlined by the reports from the Gartner group.

In 1997 they estimated that there were about 300 billion lines of computer code in use in the world. Of that they estimated that about 80% (240 billion lines) were in COBOL and 20% (60 billion lines) were written in all the other computer languages combined [Brown].

In 1999 they reported that over 50% of all new mission-critical applications were still being done in COBOL and their recent estimates indicate that through 2004-2005 15% of all new applications (5 billion lines) will be developed in COBOL while 80% of all deployed applications will include extensions to existing legacy (usually COBOL) programs.

Gartner estimates for 2002 are that there are about two million COBOL programmers world-wide compared to about about one million Java programmers and one million C++ programmers.

        • Still remember FORTH? LISP, PROLOG may be more widely used for a time. But they are pretty much dead. -mikesmith(老猫); 2005-6-9 {1257} (#2337999@0)
          本文发表在 rolia.net 枫下论坛At one time when I was a graduate student, I was told FORTH was the future of all programming language. When JAVA came around, poeple compared it to FORTH as there were similarities. How many people still remember FORTH?

          Prolog once considered an evolution as it has a higher semantic expression power than c. You can program a complex problem with only a few lines of Prolog while may need pages of code using c lanaguage. Poeple were exicited about it, especially the Japanese. How many people are still using it now?

          Consider COBOL, for years people announced it dead whenever c and c++ came around. But there are still billions of lines of COBOL code produced each year. Our banking systems are still evolved around it.

          Samething is true for Token Ring v.s. Ethernet, or ATM v.s. Ethernet. Do you still remember 6 years ago what poeple said about ATM? Wasn't that a future? ATM everywhere?

          Simple things will survive. "Easy" means more than the superiority of the technology itself. In that aspect, Java is a clear winner compared to C++. But it is not clear to me why they made J2EE so complex. .NET has a better chance. But everybody hates Microsoft.

          i just love simple stuff. So I quit programming....cannot stand its complexity.更多精彩文章及讨论，请光临枫下论坛 rolia.net

              • what's your opinion against the implementation of OO in the business/application world? -aka(棒棒); 2005-6-10 (#2339807@0)
                • I have nothing against OO in any sense. -mikesmith(老猫); 2005-6-13 {294} (#2344198@0)
                  In fact, I was quite excited about it during the early years. But I think there is no "one fits all". And if the structual code is working well with the business logic, let it be. For a time, we spent too much time to see how to apply the object model to describle what is a sequential logic.

      • I think C++ will be alive at least in the telecom industry which requires the highest performance and reliability. Look at the the ACE library and you will find the easiest and most powerful development way of C++ application -henryxy(亨利大帝); 2005-6-12 (#2342300@0)
        • also for os kernel development, embedded and real-time application. -goodchoice(body builder); 2005-6-13 (#2343377@0)
      • C/C++ is not easy to learn compared with Java/.Net. However after you master it you will treat it as the best language. Also, a C/C++ programmer can understand the system and architecture very well. -henryxy(亨利大帝); 2005-6-12 (#2342388@0)
        • Well, i am not a master of C++ but i am fairly familiar with it. I just don't like it. my fault. -canadiantire(轮胎-M.I.N.K.); 2005-6-13 (#2343407@0)

      • 那要看发展到何种程度, C 与 C++的出现及其广泛的应用是有其合理及必然性的. 我的理解是只要电脑体系结构没能够跳出“诺依曼机”, C 和 C++就不会消亡. -keepbugging(独行的猫); 2005-6-15 (#2347466@0)
    • c++/C会死？你拿什么写Linux,GNU soft,Gnome,KDE, Oracle,MySQL, Acrobat, MS office. 各种driver, firmware? -hillman(山大王); 2005-6-15 {209} (#2346991@0)
      java 不错，不过也就用在访问数据库的所谓 enterprise applications.
      写写middleware, 慢点就慢点，安全最重要。
      啥时候你见到 blizzard.com 把 starcraft 用 别的语言写了，再来谈C++死不死。这种问题还有人附和，真是怪了
    • a joke -kpax(kosmo); 2005-6-16 {108} (#2349888@0)
      After all, it should really be called ++C, since we only want to use a
      language after it has been improved.
