Here's a practical, minimal guide for using GDB in Ubuntu terminal — from launching to setting breakpoints and navigating your code. 🧰 Step 1: Compile with Debug Symbols Use -g and disable optimizations ( -O0 preferred for debugging): bash Copy Edit g++ -g -O0 -o myprog myprog.cpp 🚀 Step 2: Launch GDB bash Copy Edit gdb ./myprog You'll see a (gdb) prompt. 🎯 Step 3: Set Breakpoints You can set breakpoints in three main ways : ✅ a. At a function gdb Copy Edit (gdb) break main ✅ b. At a specific file and line gdb Copy Edit (gdb) break myprog.cpp:42 ✅ c. At a method in a class gdb Copy Edit (gdb) break MyClass::doSomething If the symbol is mangled (C++), GDB usually demangles automatically, especially if compiled with -g . ▶️ Step 4: Run the Program gdb Copy Edit (gdb) run 🧠Step 5: Navigate Command Meaning next or n Step over current line step or s Step into function call finish Run until current function returns continue or c Continue until...
Query: wired usb multiplexer vs wifi usb multiplexer for laptop ChatGPT said: Here’s a clear comparison of wired USB multiplexer vs Wi-Fi (wireless) USB multiplexer for use with a laptop — with focus on performance, reliability, latency, security , and use case suitability : 🔌 Wired USB Multiplexer (e.g. USB switch, USB sharer, or USB over IP via cable) ✅ Pros: Low Latency & High Speed : Offers native USB 2.0/3.0 speeds (up to 5-10 Gbps). Plug-and-Play : Generally no drivers or software needed. No Interference : Immune to wireless signal issues. Stable Power Delivery : Can reliably power USB devices (like cameras, storage). ❌ Cons: Limited Range : USB cables are typically limited to 2-5 meters. More Cables : Messier setup, especially in multi-device scenarios. Manual Switching (sometimes) : Cheaper models may require a physical button press to switch host access. 🧠Suitable for: Latency-sensitive tasks (e.g. debugging, flashing firmware). H...
