How to use gdb in Ubuntu Terminal

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...

Bike Notes from chatGpt: Economy speed range for 100cc, 125cc, 150cc, 200cc bikes?

 The economy speed range for 100cc, 125cc, 150cc, and 200cc bikes can vary depending on several factors such as engine capacity, fuel efficiency, weight, road conditions, and riding style. However, in general, here are the average economy speed ranges for these bikes:


1. 100cc bikes: The economy speed range for most 100cc bikes is between 40-60 km/h (25-37 mph). Riding within this range can help optimize fuel efficiency and prolong the life of the bike.


2. 125cc bikes: The economy speed range for most 125cc bikes is between 50-70 km/h (31-43 mph). Riding within this range can help balance fuel efficiency and performance.


3. 150cc bikes: The economy speed range for most 150cc bikes is between 60-80 km/h (37-50 mph). Riding within this range can offer good fuel efficiency and decent performance.


4. 200cc bikes: The economy speed range for most 200cc bikes is between 70-90 km/h (43-56 mph). Riding within this range can offer good fuel efficiency and optimal performance.


It's important to note that these are general guidelines, and the actual economy speed range may vary depending on several factors. It's always best to consult the bike's owner's manual and follow the recommended speed and maintenance guidelines for optimal performance and fuel efficiency.
