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.
