GDB Debugger Steps

• Adding debug information During Program A.C compilation: g++-g-o a.debug A.C
• Start GDB, enter under Terminal: GDB
• At this point gdb is started, loading the program that needs debugging in GDB, entering command in Terminal: File A.debug
• Looking at the code in GDB, after adding the-G command with g++, the compiled A.debug program automatically joins the breakpoint, you can use the List command to view the source code and breakpoints, in the terminal input command: List 1, when GDB will display the first breakpoint before the code.
• Press and hold the Enter key to display the previous code for the next breakpoint, and so on, you can view the breakpoint program.
• Add a breakpoint to the corresponding line, such as a breakpoint in line sixth, enter a command: Break 6
• To view breakpoints, you can enter a command: Info breakpoint can display all breakpoints in the program
• To view the nth breakpoint, to view the second breakpoint, you can enter a command: Info breakpoint 2
• Run the program, enter the command: Run
• You can enter next or step or continue and N for debugging:
  • Step can be debugged inside the function
  • Next single-Step commissioning
  • Continue run to the next breakpoint
• To view a variable, enter the print variable name, if you want to view the value of I, enter: print I
• Exit program command: Q
