Float Array Prints Hello World

luna:~$ bat -p hello.c #include <stdio.h> int main(){ float buf[]={ 1.14313921243758250594e+27, 6.657848692049645644e+28, 7.73929309656277981375e−19, 0.0f }; puts((char*)buf); } luna:~$ clang hello.c luna:~$ ./a.out Hello World! luna:~$

A terminal shows C code storing strange floating-point values in an array, then casting the array to a character pointer and printing it as “Hello World!”. The joke is that the numbers secretly encode the text in memory, making an absurdly indirect way to print a classic beginner-programming message. It is used as a reaction to clever, cursed, or unnecessarily complicated code.
