C Debugging

This lesson is part of C · All levels

Summary

Debugging is the process of finding and fixing bugs systematically, not guessing the cause. Popular methods include using debuggers such as GDB with breakpoints, execution steps, and variable value checks, or while adding printf to track data streams. Compiler with the -g flag so that the symbol information is available to the debugger, and use sanitizers to capture memory error.

Key points

Compiler with gcc -g nama.c -o names to include debug information.
Breakpoint stops the program on a certain line so that the value of the variable can be checked.
Printf debugging remains effective: print values at key dots to view the data stream.
Set the hypothesis and test it by minimizing the problem area, not changing the code randomly.
Pay attention to the compiler's warning messages and use -fsanitize=address to capture leaks and illegal memory access.
