- Static vs Dynamic Arrays
- Memory Allocation and Management
🌟 DEV
- HTML – Elements and Semantic Tags
- CSS – Selectors, Box Model, Pseudo Classes
🔍 Some Key Highlights:
-
Static arrays have a fixed size set at compile time, stored in either the stack or data segment. Access is super fast (O(1)) due to direct memory address calculation.
-
Dynamic arrays offer flexibility with size adjustment during runtime, managed via pointers and memory allocation functions like
malloc()andnew. But beware of memory leaks and undefined behavior! -
While dynamic arrays are powerful, they require careful memory management. Luckily, C++ provides safer alternatives like
std::vectorfor automatic memory management and resizing. -
HTML is like the backbone of web pages, providing the structure and content.
-
There are various HTML elements like
,,, each serving a unique purpose in creating web content.Understanding the
DOCTYPEdeclaration ensures browsers render HTML correctly, like a passport guiding them through the document.The
semanticHTML tags help the search engines and other user devices to determine the importance and context of web pages. The pages made with semantic elements are much easier to read.Examples of non-semantic elements:
