What I know about software debugging (not finished)

Introduction to Commissioning

The software is tested and debugged. Existing tests, found errors, and then debug, find bug corrections.
There are a variety of debugging options, so I'm ready to introduce all the debugging methods I've been exposed to. the various methods of debugging gdb debugging at 1.linux 2.vs2012 under the test

Debugging tips (Check bugs)
1. Print error message, get the last error (can be added after the indeterminate function)
such as: OPENPROCCSE ();
Int e= Getlasterrorr ();
Cout << E;
Tool-error lookup-Input Error code
2.Vs additional debugging.
In the place where you want to debug, sleep, next breakpoint. Then run (run, not debug)
And then
Debug-attatch to process.
3. Single-Step debugging, monitoring data
