description of ddd ddd - the data display debugger for use with c, c++, fortran, perl, java, python... from the ddd man page: The purpose of a debugger such as DDD is to allow you to see what is going on "inside" another program while it executes--or what another program was doing at the moment it crashed. DDD can do four main kinds of things (plus other things in support of these) to help you catch bugs in the act: o Start your program, specifying anything that might affect its behavior. o Make your program stop on specified conditions. o Examine what has happened, when your program has stopped. o Change things in your program, so you can experiment with correcting the effects of one bug and go on to learn about another. "Classical" UNIX debuggers such as the GNU debugger (GDB) provide a command-line interface and a multitude of com- mands for these and other debugging purposes. DDD is a comfortable graphical user interface around an inferior GDB, DBX, XDB, JDB, Python debugger, or Perl debugger.
