Hi, everyone.
Long time no see. How's everyone doing? I'm fine.
When "Foo" is used as a funtion's or procedure's name, it doesn't have too much meaning.
One of my college programming professors liked to use "foo" as a function's name when he gave the examples.
Such as
foo(x,y) {......;return}, foo1(x,y) {......return x}, foo2(x,y) {..... return x+y},
