The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...

Block comment in Ruby opens at =begin line and closes at =end line. S-Lang. The region of lines enclosed by the #<tag> and #</tag> delimiters are ignored by the interpreter. The tag name can be any sequence of alphanumeric characters that may be used to indicate how the enclosed block is to be deciphered.
if a then { if b then s1 } else s2 if a then { if b then s1 else s2 } The dangling-else problem dates back to ALGOL 60 , [ 1 ] and subsequent languages have resolved it in various ways. In LR parsers , the dangling else is the archetypal example of a shift-reduce conflict .

"subtract if possible, otherwise add" : a (0) = 0; for n > 0, a ( n ) = a ( n − 1) − n if that number is positive and not already in the sequence, otherwise a ( n ) = a ( n − 1) + n , whether or not that number is already in the sequence.
Oracle Forms version 4.5 was really a major release rather than a "point release" of 4.0 despite its ".5" version number. It was named 4.5 in order to meet contractual obligations to support Forms 4 for a period of time for certain clients so it could market 4.5 as being a patch to 4.0, even though a full install was required, rather than ...
A weak separation oracle for K is an oracle that, given a vector y in Q n and a rational number d>0, returns one of the following:: [1]: 51 Assert that y is d -near K ; Find a vector a in Q n , normalized such that its maximum element is 1, such that a ⋅ y + d ≥ a ⋅ x {\displaystyle a\cdot y+d\geq a\cdot x} for all x that are d -deep in K .
