Hello, World! -

The complexity of "Hello, World!" varies significantly depending on the language's design: A modern 'Hello, World' program needs more than just code

The tradition is most famously traced back to , who used it in a 1978 internal memorandum at Bell Laboratories titled Programming in C: A Tutorial . However, earlier versions appeared in Kernighan's 1972 tutorial for the B programming language , where it was used to illustrate external variables by dividing the phrase into multiple four-character constants (e.g., a 'hell'; b 'o, w'; c 'orld' ). Some sources even trace the concept back to 1967 with the language BCPL . Significance in Programming Hello, world!

: It allows developers to compare the complexity of different languages. For instance, Python requires a single line, while C or Java requires multiple lines of "boilerplate" code. The complexity of "Hello, World
