Use GDB to debug programs and gdb to debug programs

GDB (GNU Debuger) is a powerful Debugger in Linux. GDB allows you to view the internal structure of the program, print the variable value, set the breakpoint, debug the source code in a single step, modify the variable value during running, track the path, switch the thread, and display the assembly code.

Compile

To use GDB for debugging, you must add the-g option when compiling the program. When this option is set, GCC will add the debugging information "wedge" to the program, which can be used by GDB to interact with the program.

Gcc-g myfile. c-o myfile_debug
