Note:

Gcc-g-c main.c

Gcc-o main main.o

To generate an executable that can be debugged, you need to add the-g option at compile time, not at link time. If there is no-g, you will not see the function name, variable name of the program, all replaced by the running memory address.

Run the program

Run

Displays 10 lines of code adjacent to the breakpoint

List

Single-step debugging (inside or outside the function)

"next" strictly ensures that the control point is in the current range, while "step" follows the execution into the interior of the function.

If the breakpoint is set on the line where the function is called, use the next control point to jump directly to the next line. If you use the step control point, it jumps to the first line inside the function.

Quit

If you want to exit your program when it is paused, use the "kill" command, and if you want to exit GDB, use the "quit" command
