Why all programmers try Hello world program in 1st time

Question

Just for knowledge

Answer 1

Because it is the easiest program to make and understand 😀

Answer 2

There is a Hindi word known as "parampara" ,in English it's "tradition" of programming to write "Hello, World" 😆

Answer 3

the first thing to learn (and to practice) in programming with a new language is to print/output something on screen (to be able to show/see effect of all other languages features)...

printing "hello world" is kind of design pattern of this first task/example: it may be any word/sentence else... that's the model commonly used from decades, and will probably continue until end of times ;P

however, you just started learned C course, where there was no practices nor end of module project added... but anyway, if you go through most of other courses here, you will see that the first task to do is always to print something, but that the sentence to output vary depending on languages ;)
