Hello World in Five Programming Languages: Python, C#, C++, JavaScript, and PHP

"Hello World" is undeniably the starting point of every programmer's journey, a rite of passage etched in the memory of every beginner. Reflecting on the first programming class, the teacher sketches the simplest program on a whiteboard, and students transcribe the sacred code into their notebooks, a moment that continues to inspire exploration across many languages.

Motivated by a thirst for knowledge, the author sets a modest goal: to master and showcase how to implement the "Hello World" greeting in five distinct programming languages, chosen subjectively based on their industry recognition and popularity.

The intention is not to rank languages but to share the joy and sense of achievement that comes from writing "Hello World" in diverse syntaxes, highlighting the richness and possibilities of the programming world.

Python "Hello World"

Python, a widely used high‑level language known for its readability, uses the print() function to output text. Placing the string "Hello World" inside print() displays the greeting on the screen with simple, powerful syntax.
