Sorry if this is over kill. My bad.
The “Hello World” is a simple first coding program ‘explanation’ for new programmers utilized in many different programming languages. In computer talk, the “Hello World” is a string literal; meaning - by using the double quotes you are telling the computer - this is a ’ string of characters’ ; the characters being - Hello World - which the user (you) typed in and are then read from left-to-right inside the programming languages run-time execution. During the computer run-time (execution) [when you hit the ENTER key] a builtin function named (already coded behind the scenes for you to use) the print() function; as in, print(“Hello World”), uses the single parameter - Hello World - inside the parentheses. Depending on the Computer language you are using C, C++, Java, Python, etc,., the print() function outputs the - Hello World - to your computers’ screen on a single line. Eureka ! Your first program has successfully run. It is a passing ritual for most newbies. I remember when I wrote mine.
