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 ...
In all modern character sets, the null character has a code point value of zero. In most encodings, this is translated to a single code unit with a zero value. For instance, in UTF-8 it is a single zero byte. However, in Modified UTF-8 the null character is encoded as two bytes : 0xC0,0x80. This allows the byte with the value of zero, which is ...
0 (zero) is a number ... then one has 0 apples. In fact, ... For numeric fields it is not the value zero. For text fields this is not blank nor the empty string.
If is a set, then there exists precisely one function from to , the empty function. As a result, the empty set is the unique initial object of the category of sets and functions. The empty set can be turned into a topological space , called the empty space, in just one way: by defining the empty set to be open .
If-then-else flow diagram A nested if–then–else flow diagram. In computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are programming language constructs that perform different computations or actions or return different values depending on the value of a Boolean expression, called a condition.

An element that is a left or a right zero divisor is simply called a zero divisor. [2] An element a that is both a left and a right zero divisor is called a two-sided zero divisor (the nonzero x such that ax = 0 may be different from the nonzero y such that ya = 0). If the ring is commutative, then the left and right zero divisors are the same.
He said departments (including the Pentagon, he noted) "can't pass audits" because "the payments don't have a categorization code" and "you can't reconcile blank checks." For "many payments," he ...
