Thanks. Csaba,

I still not so clear about gdb, I am usually use microsoft Visual Studio

1. With g++ -g -o executable_name  a.o b.o ...
Can I set break point? or this one only display the place the code has prob=
lem, then go to there to modify it?

2. For ddd, Emacs, Eclipse
Are they IDC with debug inside and can set break point? I just wondering if=
 there has a software like Visual Studio IDE, so I can debug it inside it.
