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: What would be better for me 100cc or 125cc or 150cc or 200cc bike?

 The choice between a 100cc, 125cc, 150cc, or 200cc bike depends on various factors such as your riding requirements, budget, and personal preferences. Here are some general guidelines that can help you choose the right bike:


1. 100cc bikes are ideal for short commutes and city riding. They are fuel-efficient, affordable, and easy to handle, making them a good choice for beginners or riders on a budget.


2. 125cc bikes offer a bit more power than 100cc bikes, making them suitable for longer commutes and occasional highway riding. They also offer better acceleration and are more comfortable to ride for longer periods.


3. 150cc bikes are more powerful than 100cc and 125cc bikes, making them suitable for riders who want a bit more speed and acceleration. They are good for both city and highway riding, but they are generally more expensive than smaller bikes.


4. 200cc bikes are the most powerful among the options you mentioned, and they are suitable for riders who want a lot of speed and acceleration. They are good for highway riding and long commutes, but they can be more expensive to maintain and insure than smaller bikes.


Ultimately, the choice between a 100cc, 125cc, 150cc, or 200cc bike depends on your personal preferences, budget, and riding requirements. You should test ride different bikes to see which one feels most comfortable and suits your needs the best.

You said: I am new to syslog in cpp programming n just starting. Can you teach me ChatGPT said: ChatGPT Sure! syslog is a standard for logging system messages in Unix-like operating systems.

Open the Connection to syslog Before sending log messages, you need to open a connection to the syslog system. This is typically done at the start of your program: cpp Copy code openlog ( "your_program_name" , LOG_PID | LOG_CONS, LOG_USER); "your_program_name" : A string representing ...
