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...
I've glass window in my room. Now its summer so lot of sunlight comes in my room even when there is purdha on due to glass window. So anyway to cover glass by any film/etc so that I remain safe from glass window due to too much of sunlight/ uv radiations?
There are several films you can apply to your glass windows to help reduce sunlight and UV radiation coming into your room. Here are some options: Window Films: Solar Control Films: These films are specifically designed to reflect or absorb sunlight, reducing heat gain and UV rays. They come in various degrees of darkness, allowing you to choose the level of light reduction you desire. Reflective Films: These films reflect sunlight outward, keeping your room cooler and reducing glare. They can also offer some privacy benefits. UV Blocking Films: These films primarily focus on blocking UV rays while allowing some visible light to pass through. This can help protect your furniture and belongings from fading due to UV exposure. Other Options: Window Curtains/Blinds: While not a film solution, blackout curtains or blinds can be highly effective in blocking sunlight and heat gain. They come in various materials and styles to suit your taste and décor. Choosing the Right...
