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.

While they are not strictly necessary for building a web application, they can provide significant benefits in certain scenarios: 1. **Spring Framework:**    - **Dependency Injection (DI) and Inversion of Control (IoC):** Spring's DI container allows you to decouple your components and manage dependencies more easily. This promotes better code organization, testability, and scalability.    - **Aspect-Oriented Programming (AOP):** Spring AOP allows you to modularize cross-cutting concerns such as logging, security, and tr...
