GDB is a powerful UNIX program debugging tool released by the GNU open-source organization. If you are working on a UNIX platform, you will find that the GDB debugging tool has more powerful functions than the visual debugger of VC and BCB. At the same time, GDB also has a graphical debugging end such as ddd. In general, GDB
To debug a program that is already running Under UNIX, use PS to see the PID (Process ID) of the running program, and then use the GDB PID format to hook up the running program. First, using GDB to correlate the source code, and GDB,
Once you use GDB to hang up the debugger, when the program is running, you can change the running line of the currently debugged program or the value of its variable dynamically in GDB according to your debugging idea, this powerful function can let you debug your program better, for example, You can go through all the branches of the program in one run of the pr
In general, GDB accomplishes the following four main functions: (1) Start your program, you can follow your custom requirements to run the program at will.(2) allows the program to be debugged to stop at the breakpoint where you specified the reset. (Breakpoint can be a conditional expression)(3) When the program is stopped, you can check what happens in your program at this time.(4) Dynamically change the execution environment of your program. 1.

Change the execution of a program——————— Once you use GDB to hang the debugger, and when the program is running, you can dynamically change the current debugger's running circuit or its variable value in GDB based on your own debugging ideas, a powerful feature that allows you to better debug your program, for example, You can walk through all the branches of th
