I use the M++ array classes and I can get about 10 lines of code in C++ do what would take hundreds of lines of code in C. I don't have to allocate any memory or mess with pointers. Or write endless numbers of loops cycling through data arrays because I have overloaded operators that sift through the largest data sets with a single expression. I used to write in Fortran, and I would estimate that my productivity has gone up somewhere between five and ten times by moving to C++. I don't think that would happen in C. I have on occasion worked in C, just as I am occasionally forced to work in Fortran (i.e., when I'm working with existing code), and the longer I'm in it the more dramatic becomes my desire to get back to my array classes. I also do a lot of work using the Zortech compliler (the 3.0 version) which does incorporate the NCEG extensions. The M++ classes also incorporate the extensions. You are correct about them - I think they are necessary for good numerics programming. However, it appears you are incorrect about there being no C or C++ that has them. -- Ronald Schoenberg fax: 206-727-6521 University of Washington email: rons@u.washington.edu
