What is GDB Debugger? GDB (GNU Debugger) is a tool that helps programmers find and fix problems (bugs) in their programs. It works with programming languages like C, C++, and others. It allows you to see what your program is doing while it runs, so you can check where something goes wrong. Why is GDB Important? 1. Find Bugs Quickly: It helps locate and fix errors in your code. Understand Program Behavior: You can see how your program runs step by step. Saves Time: Makes debugging faster and easier. Works on Different Systems: Can be used on various operating systems and platforms. Great for Learning: Helps new 5. Great for Learning: Helps new programmers understand how their code works. Features of GDB 1. Set Breakpoints: Stop the program at specific points to check its behavior. 2. Inspect Variables: See and change tha vinlian NV avinahlan divine . Inspect Variables: See and change the values of variables during execution. . Run Step-by-Step: Go through your program line by line to find errors. . View the Call Stack: Check which functions were called and in what order. . Analyze Crashes: Examine program state when it crashes using core dumps. \ . Debug Multi-thread Programs: 6. Debug Multi-thread Programs: Handle programs that run multiple threads. 7. Remote Debugging: Debug programs running on another computer. Basic Commands in GDB Basic Commands in GDB Here are some easy commands to get started: 1. Start and Exit: ¢ gdb program_name: Start debugging a program. * quit : Exit GDB. 2. Run and Stop the Program: ¢ run: Start running the program. ° kill op the program if it’s e kill: Stop the program if it’s running. 3. Breakpoints: * break : Stop the program at a specific line. ¢ delete : Remove a breakpoint. ¢ info breakpoints : Show all breakpoints. 4. Step Through Code: 4. Step Through Code: e¢ next : Run the next line of code (skip entering functions). e step : Run the next line and go into functions. 6. Check the Call Stack: e backtrace : Show the list of function calls made so far. Benefits of Using GDB ale Benefits of Using GDB 1. Easier Debugging: You can find and fix bugs faster. Understand Your Program: See exactly how your code behaves. Open Source: It's free to use and widely supported. . Works for Complex Programs: Debug large programs with many files and functions. . Improves C , ‘ing Skills: Helps you 5. Improves Coding Skills: Helps you write better and bug-free code. GDB is an essential tool for anyone working with programs in languages like C or C++. It simplifies debugging and helps you become a better programmer. @ Why We Use GDB (Points) 1. Find and Fix Bugs: Locate errors in code easily. 2. Understand Program Behavior: See how your program runs line by line. 3. Debug Complex Programs: Handle large programs with multiple files and functions. 4. Analyze Crashes: Identify the cause of program crashes using core dumps. v . Analyze Crashes: Identify the cause of program crashes using core dumps. . Debug Multi-threaded Programs: Debug programs with multiple threads efficiently. . Save Time: Speeds up debugging with features like breakpoints and variable inspection. . Modify Code During Runtime: Change variable values or program flow witho y, ‘starting. Edurcatianal Taal: Halne naw 8. 10. Educational Tool: Helps new programmers learn how programs work in real-time. Supports Multiple Languages: Works with C, C++, Fortran, and more. Cross-Platform: Can debug programs on different operating systems and architectures.
