Jan 22, 2016 · Google can answer your question far better than I. From wiki:. The word foo originated as a nonsense word from the 1930s, the military term FUBAR emerged in the 1940s, and the use of foo in a programming context is generally credited to the Tech Model Railroad Club (TMRC) of MIT from circa 1960.[9]

foo is used as a place-holder name, usually in example code to signify that the object being named, or the choice of name, is not part of the crux of the example. foo is often followed by bar, baz, and even bundy, if more than one such name is needed. Wikipedia calls these names Metasyntactic Variables.

Foo and bar were also commonly used as file extensions. Since the text editors of the day operated on an input file and produced an output file, it was common to edit from a .foo file to a .bar file, and back again. It was also common to use foo to fill a buffer when editing with TECO.

Oct 7, 2019 · def function(foo): print(foo) As you can see, we're printing foo (called function parameter) instead of a string. This way, when we call the function, we can (and in this case, we must) replace the foo in the function call with any value, and that value will be set to foo. It's basically a local variable inside the function, which will be ...

Foo; Bar; Quux; Baz; The supposed origin of foo and bar is that "FUBAR" was WWII slang for F***ed Up Beyond All Recognition. FUBAR => FOOBAR => Foo and Bar. There isn't really a compelling reason to choose it besides the fact that no language reserves the word foo and that it's easy enough to type/read.

The term foo fighter was used by Allied aircraft pilots in World War II to describe various UFOs or mysterious aerial phenomena. The first known use of the terms in print in a programming context appears in a 1965 edition of MIT's Tech Engineering News.

Dec 6, 2013 · This probably comes from the FUBAR acronym, which stands for F***ed Up Beyond All Repair, and quickly got adapted into programming as foobar, and then foo, bar (and baz as an addition). That is programming folklore really.

It should create a function with the name foo, but not put foo in the enclosing scope, and then assign that function to the x variable (all of this happening when the expression is encountered in the step-by-step code). When I say it shouldn't put foo in the enclosing scope, I mean exactly that:

In this example, foo is a table alias. Here's how you'd use it: SELECT foo.* FROM ( SELECT RANK() OVER (ORDER BY ts.stud_mark DESC) AS ranking, ts.stud_id, ts.stud_name, ts.stud_mark FROM tbl_student ts) AS foo WHERE foo.ranking = 10

You are calling the function foo on a. That is the order since you are printing AFTER you are processing the rest of the number. Try moving the call to printf before the call to foo in foo and see if you get anything different. sum is changing because you are doing sum = sum + k and passing it to all the future calls.
