Like every learning journey in programming, it usually starts with a simple phrase: Hello World! But have you ever asked yourself—why this phrase? Where did it come from? Let’s dive in and explore its origin: The “Hello World” tradition began with the book The C Programming Language by Brian Kernighan and Dennis Ritchie, published in 1978. In one of the early examples, the authors used a simple program to print: # include <stdio.h> int main () { printf ( "Hello, world!\n" ); return 0 ; } It’s a small step for the computer, but a big one for new programmers. Since then, this phrase has become a universal first exercise when learning a new programming language. this is just a test to try and write my first blog post .
