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...
Discussion with chatGpt regarding bike TVS XL 100 HD I-Touch start (fuel saving strategy at traffic signal)
Query: For my bike while driving Traffic signal is red & countdown time is also displayed for signal to remain as red (may be from 180,120,60 sec to 0 ) Now to save fuel at before what countdown time I should turn off my bike. My bike has I Touch start feature & also kick start feature. ChatGPT said: Got it — you want to figure out: when is it worth turning off your TVS XL100 HD at a red signal to save fuel without causing hassle or extra wear. Here’s a simple answer: If the countdown is more than 15 seconds, you should turn off your bike. Detailed logic: For modern bikes (especially small engines like your XL100) with easy start features like "i-Touch" and kickstart, switching off and on doesn't hurt the engine much. Restarting the engine (i-Touch or kickstart) uses very little extra fuel — roughly equivalent to 1-2 seconds of idling . So if the wait is longer than 10–15 seconds , you save more fuel by turning it off than you lose by restarting....
